Singapore, 15 May 2020 – The current warm and humid weather is forecast to continue into the second fortnight of May 2020. Towards the end of the month, more warm nights can be expected with the onset of the Southwest Monsoon. During this period, daily maximum temperatures ranging between 34.0°C and 35.0°C are expected on most days. With the presence of the monsoon rain band over the equatorial Southeast Asia region, the coming fortnight is also expected to be as wet as the first half of this month.

2        In the second fortnight of May 2020, the prevailing low-level winds which are light and variable in direction are forecast to gradually strengthen and blow from the southeast or southwest towards the end of the month. This signals the cessation of the inter-monsoon period and the start of the Southwest Monsoon season. The Southwest Monsoon season typically extends into September and is a generally drier season compared to other times of the year.

3        On most days in the second half of May 2020, short-duration moderate to heavy thundery showers can be expected between the late morning and afternoon, with showers extending into the evening on a few days. Widespread thundery showers with gusty winds due to Sumatra squalls are expected between the predawn hours and morning on two or three days. Overall, the rainfall for May 2020 is forecast to be above-average for most parts of Singapore.

4        For the rest of the month, the daily temperature on most days is expected to range between 26°C and 34°C. and reach a high of around 35°C on a few days. Towards the end of the month, the weather during the night can be warm and humid as well when prevailing winds blow from the southeast, bringing warm and humid air from the sea over the land. Temperatures of around 28°C can be expected on some nights.

REVIEW (1 – 14 May 2020)

6       Inter-monsoon conditions prevailed over the region in the first fortnight of May 2020, and the low-level winds were generally light and variable in direction. On some days, the prevailing winds blew from the southwest or west due to the influence of low-pressure systems over the South China Sea and Indian Ocean.

7        On most days in the first half of May 2020, there were moderate to heavy thundery showers in the afternoon due to strong solar heating of land areas coupled with convergence of winds over Singapore and the surrounding vicinity. On a few dayswidespread thundery showers and gusty winds to Singapore between the pre-dawn hours and morning. On 8 May 2020, heavy thundery showers from a Sumatra squall fell over many parts of Singapore in the early and predawn hours. The daily total rainfall of 67.0mm recorded at Pasir Ris that day was the highest daily total for the first half of May 2020.

8          The warm weather in April 2020 continued into the first half of May 2020. During this period, the daily maximum temperature exceeded 34°C on several days. The highest temperature of 35.3°C was recorded at Newton on 5 May 2020. There were also a few warm nights where the night-time temperature remained around 28°C at various stations, mostly in the southern and eastern parts of the island.

9          In the first fortnight of May 2020, the eastern half of Singapore received above-average rainfall, while the western half of the island received below-average rainfall. The rainfall recorded at Admiralty was 67% below-average while that recorded at Changi was 133% above-average.

Singapore, 30 April 2020 – The warm weather in April 2020 is expected to continue into the first half of May 2020. More showers are also forecast in the next two weeks with the presence of the monsoon rain band over the equatorial Southeast Asia region. During this period, daily maximum temperatures of around 34°C are expected on most days and could reach highs of around 35°C on a few days.

2        The prevailing inter-monsoon conditions are expected to persist into May 2020. In the first half of May 2020, the low-level winds are forecast to be light and variable in direction and may blow from the southeast or southwest on some days.

3        On most days in the first fortnight of May 2020, short-duration thundery showers with frequent lightning are expected between the late morning and afternoon. This is due to strong daytime heating of land areas and convergence of winds over Singapore and the surrounding vicinity. The showers could extend into the evening on one or two of these days. In addition, the presence of low-pressure systems developing over the western Pacific Ocean and the South China Sea are expected to bring a temporary shift in the winds to blow from the southwest or west over Singapore and the surrounding vicinity. This could bring a few days of widespread thundery showers with occasional gusty winds between the predawn and morning, arising from the passage of Sumatra squalls over the island. Overall, the rainfall for Singapore in the first fortnight of May 2020 is forecast to be above-normal over most parts of the island.

4        May is normally one of the warmest months of the year. The first half of May 2020 is forecast to be warm with the daily temperature on most days ranging between 25°C and 34°C. On a few days, the daily maximum temperature could rise to around 35°C. On some nights, warm and humid conditions with night-time temperatures of around 28°C are expected when prevailing winds blowing from the southeast bring warm and humid air from the sea.

REVIEW (1 – 29 April 2020)

6         The Northeast Monsoon that prevailed over Singapore since December 2019 has ended with the onset of inter-monsoon conditions in end April 2020. The low-level winds in the region weakened in late April 2020 and have become light and variable in direction.

7          April 2020 was wetter compared to the first three months of 2020. On most days in April 2020, thundery showers fell over the island in the afternoon due to strong solar heating of land areas. On 7 April 2020, a Sumatra squall brought widespread heavy showers to many parts of Singapore in the early and predawn hours. The daily total rainfall of 115.0mm recorded at Tuas that day was the highest daily total for April 2020.

8          April 2020 was also warm and humid. At the Changi climate station, the mean monthly temperature for April 2020 of 28.9°C (as of 29 April 2020) was 0.9°C higher than the month’s long-term average. Higher than usual temperatures were experienced over many parts of the island during the month. On most days, the daily maximum temperature reached 34°C, and exceeded 35°C on 15 days. The highest daily maximum temperature of 35.8°C was recorded at Clementi on 10 April 2020.  There were also a few warm nights where the night-time temperature hovered around 28°C, mainly in the southern and eastern parts of the island.

9          About half of the island recorded above-normal rainfall in April 2020. The rainfall recorded at Jurong was 37% above average while that recorded at MacRitchie was 42% below average.

Singapore, 15 April 2020 – According to the Meteorological Service Singapore, more thundery showers can be expected over Singapore in the second fortnight of April 2020. This is due to the onset of inter-monsoon conditions and the presence of the monsoon rain band over the equatorial Southeast Asia region during the period. The current warm weather is also expected to continue for the rest of the month.

2          In the second fortnight of April 2020, the low-level winds blowing from the northwest or northeast are forecast to gradually weaken and become light and variable in direction. This signals the cessation of the Northeast Monsoon season and the start of the inter-monsoon period, which is forecast to extend into May 2020.

3          April is typically a month with high lightning activity, and also one of the warmest months of the year. In the early part of the coming fortnight, a brief intrusion of a dry air mass extending from the South China Sea to the equatorial Southeast Asia region is expected to bring dry and warm weather to Singapore. On most days in the fortnight, short-duration thundery showers with frequent lightning are expected between the late morning and afternoon. On one or two of these days, the thundery showers could extend into the evening. The thundery showers are due to strong daytime heating of land areas coupled with convergence of winds over Singapore. Overall, the rainfall for April 2020 is expected to be above-normal over most parts of the island.

4          While more showers are forecast in the coming fortnight, warm conditions can still be expected on some days. The daily temperatures are expected to range between 24°C and 34°C on most days. On a few days during the fortnight, the daily maximum temperature could reach a high of around 35°C.

REVIEW (1 – 14 April 2020)

6          In the first fortnight of April 2020, weak Northeast Monsoon conditions prevailed and the low-level winds over Singapore and the surrounding region blew from northwest or northeast.

7          Warm weather continued to prevail in the first two weeks of April 2020. During this period, the daily maximum temperature exceeded 34.0°C on most days. On six of these days, the daily maximum temperature was at least 35.0°C, with the highest temperature of 35.8°C recorded at Clementi on 10 April 2020.

8          More rain fell over Singapore in the first fortnight of April 2020 compared to the last fortnight of March 2020. Most of the thundery showers occurred in the afternoon due to strong solar heating of land areas. On 7 April 2020, large-scale wind convergence over the surrounding region triggered a Sumatra squall which brought widespread heavy showers to many parts of Singapore in the early and predawn hours. The daily total rainfall recorded that day was 115mm at Tuas, which is the highest recorded for the first fortnight of April 2020.

9          Most parts of the island recorded above-average rainfall in April 2020. The rainfall recorded at Kranji was 91% above-average while that recorded at MacRitchie was 36% below-average.

Singapore, 1 April 2020 – In the first fortnight of April 2020, Singapore and the surrounding region can expect more showers with the proximity of the monsoon rain band close to the Equator. The current warm conditions are forecast to continue in the first two weeks of April 2020 with daily maximum temperatures reaching a high of around 35°C on a few days.

2          Climatologically, April is one of the warmest months of the year, with high lightning activity. During this fortnight, short-duration thundery showers are expected in the afternoon on most days due to strong daytime heating of land areas coupled with convergence of winds over Singapore. On one or two of these days, the thundery showers could extend into the evening. On a few days, a brief intrusion of a dry air mass extending from South China Sea over the region could bring dry and warm weather over Singapore. Overall, rainfall for the first fortnight of April 2020 is expected to be near-normal over most parts of Singapore.

3          While more rain days are expected in the first half of April 2020 compared to the previous fortnight, warm conditions can still be expected on some days. The daily temperatures are expected to range between 25°C and 34°C on most days. The daily maximum temperature could reach a high of around 35°C, in particular on days when there are few clouds in the sky.

4          The prevailing Northeast Monsoon conditions with low-level winds blowing from the northeast or east are expected to persist in the first fortnight of April 2020. Around the end of the fortnight, a gradual weakening of the low-level winds can be expected, signalling the transition to inter-monsoon conditions. The later than usual onset of the inter-monsoon this year, normally by end March, could be attributed to more frequent high-pressure systems over the Western Pacific Ocean which brought persistent easterly winds to the surrounding region.

REVIEW (1 – 31 March 2020)

6         Northeast Monsoon conditions prevailed in March 2020. During the period, the low-level winds over Singapore and the surrounding region blew mainly from the northwest or northeast. Most of Southeast Asia including Singapore experienced dry and warm conditions in March 2020.

7         In Singapore, it was warm on most days in March 2020. There were 27 days with daily maximum temperatures exceeding 34.0°C, and 10 days when the daily maximum temperature was more than 35.0°C. The month’s highest daily maximum temperature of 36.3°C was recorded at Paya Lebar on 13 March 2020, the highest recorded so far this year.

8          At the Changi climate station, the mean monthly temperature for March 2020 of 28.6°C was 1.1°C higher than the month’s long-term average. The monthly mean minimum temperature for March 2020 was 25.9°C. This was 1.3°C higher than the March long-term average and is the third highest mean minimum temperature recorded for March since 1929, after March 2016 (26.6°C) and March 1998 (26.3°C).

9          During the month, the occasional intrusion of a dry air mass from the southern South China Sea over Singapore and the surrounding vicinity brought little or no rainfall over a two-week period. In the last week of March 2020, it was generally wet over most parts of the island. This was due to the passage of the Madden-Julian Oscillation (MJO)[1] which enhanced the development of thunderstorm clouds over Singapore and the surrounding region. Most of the thundery showers in March 2020 fell in the afternoon due to large-scale wind convergence over the surrounding vicinity. Thundery showers fell over many areas of the island on 23 March 2020. The daily total rainfall recorded that day was 87.8mm at Pulau Ubin, which is the highest recorded for March 2020.

10        Singapore received below normal rainfall in March 2020. The highest anomaly of 67% below average was recorded at Seletar. The lowest anomaly of 14% below average was recorded at Sentosa.

[1] The MJO is characterised by an eastward propagation of clouds and rainfall over the tropical regions from the Indian Ocean to the western Pacific Ocean, with a period of between 30 and 60 days on average. The MJO consists of two phases – an enhanced rainfall (convection) phase and a suppressed rainfall phase.

Singapore, 16 March 2020 – The warm weather experienced in the first fortnight of March 2020 is expected to persist for the rest of the month. The daily maximum temperature on most days in the coming fortnight is forecast to be around 34°C and could reach a high of around 36°C on a few days.

2          Despite the warm conditions, short-duration moderate to heavy thundery showers can still be expected over parts of Singapore in the afternoon on some days. The thundery showers are due to strong solar heating of land areas and convergence of winds in the surrounding vicinity. On one or two days, the thundery showers could extend into the evening. Overall, the rainfall for March 2020 is forecast to be below normal over most parts of Singapore.

3          In the coming fortnight, the prevailing Northeast Monsoon conditions with low-level winds blowing from the northeast or east are expected to persist. However, a gradual weakening of the low-level winds to become light and variable in direction can be expected around the end of the month.

REVIEW (1 – 27 February 2020)

5          The Northeast Monsoon conditions prevailed over Singapore and the surrounding region in February 2020.

6          During the month, it was windy on most days with winds blowing from the north or northeast. The monsoon rain band remained south of the Equator, and little or no rain fell over the island in the first week of February 2020. On most days for the rest of the month, occasional brief showers fell over parts of the island. On a few days in February 2020, strong daytime heating of land areas coupled with converging winds over the island brought moderate to heavy thundery showers over many areas between the afternoon and evening. The highest daily total rainfall of 108.8mm for February 2020 (as at 27 February 2020) was recorded at Tuas on 10 February 2020 following a heavy downpour in the late afternoon and evening.

7          Singapore’s daily maximum temperature in February 2020 (as at 27 February 2020) ranged from 31.0°C to 35.5°C.  The highest daily maximum temperature of 35.5°C was recorded on 16 February 2020 at Admiralty. The lowest daily maximum temperature of 31.0°C was recorded on 11 February 2020 when widespread thundery showers fell over the island from the late morning to the early hours of 12 February 2020. The daily minimum temperature was between 22.8°C and 25.2°C.

8          At the Changi climate station, the mean monthly temperature for February 2020 (as at 27 February 2020) was 27.8°C. This is 0.7°C higher than February’s long-term average temperature.  In addition, the average daily wind speed recorded at the station in February 2020 was 13.0 km/hr (as at 27 February 2020). This could make February 2020, together with February 1987 and 2010, the second windiest February on record since continuous wind records commenced in 1984. The windiest February on record occurred in 2014, with an average daily wind speed of 13.7 km/h.

9          Most parts of the island recorded below-normal rainfall in February 2020. The highest anomaly of 68% below-average was recorded at Choa Chu Kang. The rainfall recorded over Paya Lebar was 14% above-average.

WEATHER OUTLOOK (31 January – 15 February 2020)

1          For the first fortnight of February 2020, the Meteorological Service Singapore (MSS) forecasts warm and occasionally windy conditions on most days. Afternoon thundery showers are also expected later in the fortnight. The prevailing Northeast Monsoon season will continue, with low-level winds blowing from the northwest or northeast.

2          In the first half of the fortnight, the monsoon rain band is forecast to be located south of the Equator, and rain cloud formation over Singapore and the surrounding vicinity is likely to be suppressed. This is expected to bring warm and occasionally windy conditions on most days during the period. With the migration of the monsoon rain band closer to the Equator in the latter half of the fortnight, enhanced thunderstorm cloud development can be expected over Singapore. This is forecast to bring short-duration moderate to heavy thundery showers mostly in the afternoon on some days. The showers on most of these days are expected over parts of the island, and could be widespread on one or two days. Overall, rainfall for the first fortnight of February 2020 is forecast to be below normal over most parts of Singapore.

3         With warm conditions forecast in the first fortnight of February 2020, the daily temperature on most days is expected to range between 24°C and 34°C.

REVIEW (1 – 30 January 2020)

5          Northeast Monsoon conditions prevailed over Singapore and the surrounding region in January 2020. On most days during the month, the low-level winds blew from the north or northeast.

6          It was relatively windy on most days in January 2020, particularly during the first two weeks of the month. In the second half of January 2020, a weakening of the prevailing winds and the migration of the monsoon rain band closer to the equatorial Southeast Asia region brought more rainfall to Singapore and the surrounding vicinity. On some days in the second half of the month, strong daytime heating of land areas coupled with convergence of winds in the surrounding vicinity brought moderate to heavy thundery showers to Singapore in the afternoon. The intense thundery showers on 29 January 2020 recorded a daily total rainfall of 185.2mm at Jurong Island. This was the highest daily total rainfall recorded for January 2020 (as at 30 January 2020).

7          The second fortnight of January 2020 was generally warmer compared to the first fortnight of the month. The daily maximum temperature was between 31.6°C and 33.5°C in the first half of January 2020, and ranged between 32.0°C and 35.4°C on all days in the second half of the month except on 21 January 2020. On 21 January, the daily maximum temperature only reached 28.6°C due to several spells of widespread thundery showers that fell over the island between midnight and 3pm. The highest daily maximum temperature of 35.4°C was recorded at Newton on 26 January 2020. At the climate station in Changi, the mean monthly temperature for January 2020 of 27.7°C (as of 30 January 2020) was 1.2°C higher than the long-term average. January 2020 is on track to be the fourth warmest January since temperature records began in 1929.

8          Most parts of the island recorded below-average rainfall in January 2020. The highest anomaly of 61% below average was recorded at Changi. The rainfall recorded over the southwestern part of Singapore around Jurong was 16% above-average.

WEATHER OUTLOOK (31 December 2019 – 15 January 2020)

Singapore, 31 December 2019 – The prevailing wet phase of the Northeast Monsoon season in the region is forecast to continue into January 2020. The low-level winds during the first two weeks of the year are expected to blow from the northwest or northeast.

2        From the eve of the New Year, the northeasterly winds over the South China Sea, including Singapore are forecast to strengthen and persist before weakening around the end of the week. This is expected to bring windy conditions throughout the week, including on New Year’s Day. Toward the end of the week, periods of light to moderate showers are expected on a few days. In the second week of January 2020, convergence of winds coupled with strong daytime heating of land areas is likely to bring short-duration moderate to heavy thundery showers, mostly in the afternoon on 3 to 4 days. In addition, the presence of a low-pressure system over the South China Sea could bring widespread thundery showers accompanied by gusty winds to Singapore between the predawn and morning on one or two days. Overall, the rainfall for the first two weeks of January 2020 is likely to be below-normal over most parts of Singapore.

3         In the first fortnight of January 2020, the daily temperatures on most days are forecast to range between 24°C and 33°C, and could dip to a low of around 23°C on a few nights. The daily maximum temperature could still reach a high of around 34°C on a few days.

REVIEW (1 – 30 December 2019)

5        Northeast Monsoon conditions persisted over Singapore in December 2019, with low-level winds blowing mainly from the north or northeast.

6         December 2019 was a relatively wet month. Strong solar heating of land areas coupled with convergence of winds in the surrounding region brought moderate to heavy thundery showers in the afternoon on the first few days of the month. The intense thundery showers on 2 December 2019 recorded a daily total rainfall of 102.8mm at Bukit Panjang. This was the highest daily total rainfall recorded for December 2019 (as of 30 December 2019).

7          A surge of northeast monsoon winds prevailed over the equatorial South China Sea region in the first half of the month. Between 5 and 15 December 2019, the surge brought cloudy and windy conditions to Singapore. During the period from 9 to 11 December 2019, periods of moderate to occasionally heavy rain showers fell over the island, and over the last three days (13 to 15 December 2019) of the fortnight, the rain showers were widespread and fell continuously before dissipating in the evening of 15 December 2019. The highest daily total rainfall recorded throughout this monsoon surge event was 100.4 mm on 9 December 2019 at Pulau Ubin. In the second half of December 2019, the thundery showers were of short-duration and fell mostly in the afternoon. The heaviest rainfall recorded during the period was 63.3 mm at Queenstown on 18 Dec 2019 (as of 30 Dec 2019).

8          The monsoon surge and the accompanying rainy weather in the first half of the month brought several cool days. From 8 to 15 December 2019, the daily maximum temperature ranged between 25.2°C and 29.9°C on all days except 12 December 2019.
