Temperatures in 2nd half of August forecasted to dip as low as 23 degrees Celsius

Temperatures in the second half of August could dip to 23 degrees Celsius on one or two days, said the Meteorological Service Singapore (MSS) in an advisory on Tuesday (Aug 16). 

The daily temperature on most days in the next two weeks is expected to range between 24 degrees Celsius and 33 degrees Celsius, although it could possibly reach daily highs of around 34 degrees Celsius on some days. 

Short-duration moderate to heavy thundery showers are expected on most late mornings and afternoons in the next fortnight. A handful of wet mornings with thundery showers and gusty winds are forecasted due to the Sumatra Squalls. 

Thundery showers may likely occur on several nights due to convergence of winds in the surrounding vicinity. This is a result of the prevailing Southwest Monsoon conditions that are forecasted to persist over Singapore and the surrounding region with low-level winds blowing from the Southeast or Southwest.

Overall, rainfall in the second half of August is expected to surpass that of the first half, and is likely to be above-average over most parts of the island.

The MSS also added that several warm and humid nights with minimum night-time temperatures of 28 degrees Celsius can be expected particularly in the eastern and southern coastal areas. 

This is due to prevailing winds blowing from the southeast which bring warm and humid air from surrounding areas.
