Thundery Showers Expected To Continue For The Rest of February 2022

Singapore, 16 February 2022 – The generally wet weather experienced in the first fortnight of February 2022 is expected to continue into the second half of the month, with the prevailing winds blowing from the northwest or northeast.

2    During the second half of February 2022, the monsoon rain band is forecast to lie over the equatorial Southeast Asia region and continue to bring showers to Singapore and the surrounding vicinity. Short-duration thundery showers can be expected in the afternoon on most days, extending into the evening on some occasions. On one or two days, the presence of a mass of dry air over the surrounding South China Sea may bring stable atmospheric conditions and generally fair and warm weather to Singapore.

3    In the latter half of the fortnight, the prevailing winds from the northeast are forecast to strengthen. On some days during this period, large-scale convergence of winds over Singapore and the surrounding region may trigger widespread and heavy thundery showers over the island. Overall, the rainfall for February 2022 is forecast to be above-average over most parts of the island.

4    For the rest of February 2022, the daily temperature is forecast to range between 24°C and 33°C on most days. On days with less cloud cover, the maximum temperature may reach around 34°C.
