REVIEW OF THE PAST TWO WEEKS (1 – 15 JANUARY 2025)

5      Northeast Monsoon conditions prevailed over Singapore and the surrounding region in the first fortnight of January 2025. During the period, the low-level winds blew mainly from the north or northeast.

6     A strengthening of the high-pressure system over northern continental Asia brought a surge of moderate to strong northeast monsoon winds over the South China Sea on several days of January 2025. The surge brought cool and wet weather over Singapore between 10 and 13 January 2025. The daily total rainfall of 241.8 mm recorded at Pulau Tekong on 10 January 2025 was the highest daily total rainfall ever recorded in January, exceeding the previous record of 238.2mm on 30 January 2011.

The highest daily maximum temperature of 34.3 degrees Celsius was recorded on 5 January 2025 at Jurong.  During the monsoon surge event between 10 and 13 January 2025, there were three days where the highest daily maximum temperature was below 28 degrees Celsius. On 11 January 2025, the highest daily maximum temperature was 25.7 degrees Celsius recorded at East Coast Parkway and the daily minimum temperature at Newton dipped to 21.6 degrees Celsius, the lowest temperature for the first fortnight of January 2025.
