More showers are expected in the second half of this month, with wet and warm conditions forecast, the Meteorological Service Singapore said yesterday.
Moderate to heavy short thundery showers are forecast between the late morning and afternoon on six to eight days. In the last week of the month, there could be widespread thundery showers accompanied by occasional gusty winds between the pre-dawn hours and early morning on two or three days, due to the eastward passage of Sumatra squalls.
May is one of the warmest months of the year, and warm conditions are expected to continue into the second half of the month. Daily maximum temperatures on a few afternoons could reach a high of around 35 deg C. On a few nights, the minimum temperature could drop to around 27 deg C.
On most days, however, daily temperatures are expected to be between 25 deg C and 34 deg C.
About half of Singapore received above-normal rainfall during the first fortnight of this month. Rainfall was highest around Choa Chu Kang, where 229mm (108 per cent above average) was recorded.
The daily maximum temperature for the first two weeks of May ranged from 30.8 deg C to 35.2 deg C.
The warm night-time temperatures are attributed to light winds blowing from the south-east, which bring warm and humid air from the sea over to land.
