Short, thundery showers and warm weather expected in Singapore till end of May

SINGAPORE – Short, thundery showers are expected over parts of Singapore on most afternoons for the rest of May, said the weatherman on May 15.

These are expected to extend into the evening occasionally.

The second half of the month is also likely to be warm, with temperature highs forecast to be at least 33 deg C.

Sumatra squalls may also bring widespread thundery showers accompanied by gusty winds in the pre-dawn hours and morning on a few days, said the Meteorological Service Singapore.

Total rainfall for the last two weeks of May is forecast to be near the long-term average across most parts of the island.

The daily maximum temperature is expected to range between 33 deg C and 34 deg C on most days, with a high of about 35 deg C on a few days.

In its review of the weather in the first fortnight of May, the Met Service said inter-monsoon conditions prevailed over Singapore, with winds generally light and variable in direction.

Thundery showers fell over parts of Singapore on most days during this period.
