SINGAPORE: More thundery showers are expected in the second half of August than the first half, said the Meteorological Service Singapore on Tuesday (Aug 16). 

In its fortnightly outlook, the Met Service said that short moderate to heavy thundery showers can be expected between the late morning and afternoon on most days. There may also be thundery showers over Singapore on a few nights.

"In addition, Sumatra squalls may bring widespread thundery showers with occasional gusty winds in the pre-dawn and morning on a few days," said the Met Service.

Overall, more rainfall is expected in the second half of August compared to the first half of the month. The overall rainfall for August will likely be above-average over most parts of the country, said the Met Service.

However, there could still be a few warm days in the coming fortnight despite the expected showers.

On most days, the daily temperature is forecast to range between 24 degrees Celsius and 33 degrees Celsius, with some days reaching daily highs of about 34 degrees Celsius. 

On a few rainy days, the daily minimum temperature may dip to below 23 degrees Celsius.

Warm and humid conditions with minimum temperatures of up to 28 degrees Celsius can be expected on a few nights, particularly in the eastern and southern coastal areas of the country. 


The first half of August saw less wet weather, with several days with short, localised thundery showers over parts of the country mainly in the late morning and afternoon.

On the afternoon of Aug 2, large-scale convergence of winds over Singapore and the surrounding region resulted in moderate to heavy thundery showers over many areas of the country. Some showers were particularly intense over the western and northern parts of Singapore.

The total rainfall of 78.6 mm recorded at Kranji was the highest daily total rainfall recorded for the first half of the month, said the Met Service. 

The daily maximum temperature ranged from 29.5 degrees Celsius to 35.1 degrees Celsius in the first half of August, with the highest daily maximum temperature recorded at Marina Barrage on Aug 11. 

On a few nights, the daily minimum temperatures over the southern, eastern and western coastal areas of the country were above 28 degrees Celsius.

In the first two weeks of August, the western half of Singapore received above-average rainfall, while the eastern half of the country received below-average rainfall, said the Met Service.

The rainfall recorded at Jurong was 105 per cent above average while that recorded at Tanjong Katong was 83 per cent below average.
