Wet and slightly cooler weather expected till year end

Wet and cool weather is expected for the second half of December, said the Meteorological Service Singapore (MSS) in a press release on Friday (Dec 16).

As winds are forecast to blow from the northwest or northeast for the rest of December, the MSS expects the wet phase of the Northeast Monsoon to continue into January 2023, followed by the dry phase from February to mid-March.

Moderate to heavy thunder showers are expected over parts of the island in the afternoon on most days for the next fortnight, and might extend into the evenings.

A brief strengthening of the northern winds over Singapore can also be expected in the coming fortnight. This might cause windy conditions with occasional showers on two or three days.

Daily temperatures are forecasted to range between 24 degrees Celsius and 32 degrees Celsius for most days of the next fortnight. While the highest daily temperature may peak around 33 degrees Celsius, rainy days could cause the temperature to drop to as low as 23 degrees Celsius.

On most days of the first fortnight of December, Singapore experienced short-duration thundery showers which extended into the evening on a few occasions. 

MSS said that large-scale convergence of winds on Dec 11 led to the development of a Sumatra squall, bringing widespread thundery showers in the morning and early afternoon.

Overall, the total rainfall for December is forecast to be near average over most parts of Singapore.
