Singapore, 16 July 2020 – More thundery showers can be expected in the second fortnight of July 2020. During this period, daily minimum temperatures of around 22°C can be expected on a few days. The daily maximum temperature is forecast to range between 32°C and 33°C on most days and a high of 34°C can be reached on one or two days.

2          In the coming fortnight, the prevailing Southwest Monsoon conditions are forecast to persist, with low-level winds blowing from the southeast or southwest. On a few days in the last week of July 2020, the winds are forecast to blow from the west.

3          The monsoon rain band is forecast to remain over the equatorial Southeast Asia region in the next two weeks. This is expected to bring short-duration moderate to heavy thundery showers between the late morning and afternoon on many days, and may extend into the evening on a few of these days. Thundery showers are also expected on a few nights due to the presence of large-scale wind convergence over Singapore and the surrounding vicinity. In addition, the passage of Sumatra squalls is expected to bring widespread thundery showers with gusty winds over the island in the morning on one or two days in the last week of the month. The second half of July 2020 is expected to see more rainfall than the past fortnight, and the overall rainfall for July 2020 is forecast to be above-average over most parts of Singapore.

4          During the fortnight, the daily temperature is forecast to range between 24°C and 33°C. Although showers are expected on many days during this period, the daily maximum temperature could still reach a high of around 34°C on one or two days. Lows of around 22°C can be expected on a few rainy days.

REVIEW (1 – 15 July 2020)

6          In the first fortnight of July 2020, Southwest Monsoon conditions prevailed over Singapore and the surrounding region. During the period, the low-level winds blew mostly from the southeast or southwest, and from the west on a few days.

7          In the first two weeks of July 2020, thundery showers fell over parts of the island mostly in the late morning and early afternoon due to strong solar heating of land areas. On a few days, the showers continued into the evening and night due to large-scale convergence of winds in the surrounding region. The highest daily total rainfall recorded in the first fortnight of July 2020 was 125.6mm at Buona Vista on 9 July 2020.

8          The second week of July was cooler compared to the first week due to more rainy weather. The lowest daily maximum temperature recorded was 25.9°C at Khatib on 13 July 2020 arising from overcast skies and widespread thundery showers that day. The highest daily maximum temperature in the first half of the month was 33.9°C recorded at Pulau Ubin on 5 July 2020.

9          About half of the island recorded above-normal rainfall in the first half of July 2020. The rainfall recorded at Jurong Pier was 90% above average while that recorded at Changi was 48% below average.

Singapore, 16 June 2020 – According to the Meteorological Service Singapore (MSS), the current wet weather is expected to continue in the second half of June 2020. During this period, thundery showers are expected on most days and this could bring a slight easing of the warm temperatures felt in recent weeks.

2        The prevailing Southwest Monsoon is forecast to persist for the rest of June 2020 and extend to end September 2020. For the rest of this month, the low-level winds over Singapore are forecast to blow from the southeast or south, and shifting to blow from the southwest or west on some days.

3        In the second fortnight of June 2020, the monsoon rain band is expected to remain close to the equatorial region. On many days in the fortnight, short-duration moderate to heavy thundery showers can be expected between the late morning and early afternoon, and extending into the late afternoon on a few days. The convergence of winds in the surrounding vicinity could also bring thundery showers on a few nights. Widespread thundery showers with gusty winds due to the passage of Sumatra squalls are forecast on two or three days between the predawn hours and morning. Overall, the rainfall for June 2020 is forecast to be above-average over most parts of the island.

4        The wetter weather expected in the second half of June 2020 will help to slightly ease the warm and humid conditions felt in recent weeks. The daily temperature on most days is forecast to range between 25°C and 33°C. There could still be a few warm days where the daily maximum temperature could reach a high of around 34°C.

REVIEW (1 – 15 June 2020)

6      In the first fortnight of June 2020, Southwest Monsoon conditions prevailed over Singapore and the surrounding region.  The prevailing winds blew from the southeast or south on most days, and from the southwest or west on a few days.

7       During the first two weeks of June 2020, most of the thundery showers occurred in the afternoon due to strong solar heating of land areas. There were a few nights where moderate to heavy thundery showers fell over the island due to convergence of winds in the region. On 13 June 2020, widespread moderate to heavy thundery showers fell over the island between the predawn hours and morning. This was due to the convergence of winds over the region under the indirect influence of Tropical Storm “Nuri” as it intensified over the South China Sea. The daily total rainfall of 84.0mm recorded at Jurong West that day was the highest daily total for the first half of June 2020.

8        The first half of June 2020 was less warm compared to the last two months due to more days of rain. The daily maximum temperature ranged between 31°C and 34°C on many days, and reached 35°C or more on a few days. The highest daily maximum temperature of 35.6°C was recorded at Admiralty on 2 June 2020. There were a few warm nights where the night-time minimum temperature was around 28°C over the eastern, southern and western parts of the island.

9         Almost all parts of the island received above average rainfall in the first fortnight of June 2020. The highest anomaly of 155% above average was recorded at Jurong West. The anomaly was lowest at Admiralty at 4% below average.

REVIEW (1 – 31 May 2020)

6      In the second half of May 2020, the light and variable winds over Singapore and the surrounding region gradually strengthened to blow from the southeast or southwest. This shift in winds signalled the end of the inter-monsoon period and the start of the Southwest Monsoon season in late-May 2020.

7        On most days in the month, moderate to heavy thundery showers fell over the island in the afternoon due to strong solar heating of land areas. On a few of these days, the showers extended into the evening.  On two occasions, Singapore experienced thundery showers in the night due to large-scale wind convergence in the surrounding region.  The wet weather in May 2020 was also due to the passage of Sumatra squalls over Singapore on some days. This brought widespread thundery showers and gusty winds between the early and predawn hours. On 22 May 2020, moderate to heavy thundery showers fell over the island in the afternoon and evening.  The daily total rainfall of 99.2mm recorded at Jurong that day was the highest daily total for May 2020.

8          May 2020 was also a warm month. The daily maximum temperature exceeded 34°C on most days. On 8 of these days, the daily maximum temperature reached 35°C or more. The highest daily maximum temperature of 35.8°C was recorded at Admiralty on 22 May 2020. There were a few warm nights where the night-time minimum temperature was around 28°C, over the southern and eastern parts of the island. At the Changi climate station, the mean monthly temperature for May 2020 was 28.9°C, which was 0.6°C higher than the month’s long-term average.

9          Most parts of the island received above-average rainfall in May 2020. The highest anomaly of 68% above average was recorded at Pasir Ris. The anomaly was lowest at Seletar at 35% below average.

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.

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.
