Warm weather and thundery showers expected in the first half of April 2022

Warm weather is expected to continue into the first two weeks of April, with thundery showers forecasted on some days, according to a National Environmental Agency (NEA) advisory released on Apr 1.

Short duration thundery showers are expected in the afternoons and evenings, while certain days might bring about a more intense wave of thunderstorms due to prevailing winds around Singapore, said the advisory. 

As April is one of the warmest months climatologically, there is a higher chance for lightning activity to occur. Moderate to heavy thundery showers are most likely to occur in the afternoon. 

Daily temperatures are forecast to fall between 24 to 34 degrees Celsius, with a daily maximum temperature of 35 degrees Celsius. 

The rainfall for the month of April is predicted to be near average over most parts of Singapore. However, gusty winds are to be expected, said the advisory.

A review done by NEA in March observed that thundery showers mainly occurred during the afternoon and evening, in the pre-dawn hours and the morning. The heaviest rainfall was over the southern and western parts of Singapore. 

The daily total rainfall reached its highest for the entire month on Mar 7 at Jurong West, measured at 134.2 mm. It was ranked the second wettest day in the past 10 years. 

“March 2022 was a warm month. Strong solar heating of land areas coupled with light wind conditions resulted in warm temperatures on most days,” said NEA in the review. 

There were seven days in March where the temperatures peaked at 35 degrees Celsius. 

The highest daily temperature recorded stood at 36.2 degrees Celsius. It was recorded on 19 Mar, at Ang Mo Kio. 

The lowest daily minimum temperature recorded was 21.8 degrees Celsius at Pulau Ubin on Mar 21 and Admiralty on Mar 31.
