This will continue to bring dry and warm weather on most days over the next two weeks. Some brief respite can be expected towards the second week of March 2019 with a weakening of the low level winds over the region. This could bring about four to five days of short-duration thundery showers in the afternoon. Overall, the rainfall for the first fortnight of March 2019 likely to be below-normal.

REVIEW (1 – 28 February 2019)

5         In February 2019, generally dry and warm conditions prevailed over Singapore and the surrounding region, and the low level winds were blowing from the north or northeast.

6         During the month, Singapore experienced dry, warm and occasionally windy weather on most days. For a brief period in the second half of February 2019, a weakening of the northeasterly winds, with a temporary northward shift of the monsoon rain band to the equatorial region coupled with strong solar heating of land areas brought short-duration thundery showers in the afternoon on a few days. The thundery showers that fell over many areas in the afternoon of 19 February 2019 recorded a daily total rainfall of 69.3 mm at Woodlands. This is the highest daily total rainfall recorded for February 2019.

7         February 2019 was a significantly warm month. The daily maximum temperature during the month ranged between 33.0°C and 35.5°C. The highest daily maximum temperature of 35.5°C was recorded at Choa Chu Kang on 9 February 2019. On most days in the month, the daily minimum temperature was between 23°C and 26.1°C. The lowest daily minimum temperature in February 2019 was 21.4°C, recorded on 18 February 2019 at Admiralty.  This low temperature was due to the passage of a Sumatra squall that brought showers over the island in the predawn and early morning, and some respite to the warm conditions that were felt in the days before.

8         At the climate station in Changi, the mean monthly temperature for February 2019 was 28.2°C, 1.10C warmer than the long-term average for February. This makes February 2019 the third warmest February since temperature records began in 1929, after February 1998 and 2010 (28.9°C) and February 2005 (28.5°C).

9        Singapore received significantly below-normal rainfall in February 2019. The highest rainfall of 114.2mm (18% below average) was recorded at Admiralty. Rainfall was lowest at Queenstown where 20.2mm (85% below average) was recorded.
