Warm temperatures and thundery showers to continue in May
Daily temperatures are forecasted to rise to as high as 35 degrees Celsius.
Thundery showers and warm temperatures from the last fortnight of April are to continue in May, according to a National Environmental Agency (NEA) advisory released on Apr 29.
With the prevailing inter-monsoon conditions, short-duration moderate to heavy thundery showers with lightning are expected between the afternoon and evenings on certain parts of the island on some days.
In the first fortnight of May, the presence of low-pressure systems over the South China Sea may induce widespread thundery showers with gusty winds over Singapore during the pre-dawn hours and morning.
The warm conditions from April are expected to continue with daily temperatures to range between 24 to 34 degrees Celsius on most days, and could reach 35 degrees Celsius on some days.
On rainy days, the daily minimum temperature may drop to a low of around 23 degrees Celsius.
Overall, the rainfall for May is expected to be near-normal over most parts of Singapore, said the advisory.
Half of Singapore had above average rainfall in April
A review done by NEA in April observed that there were more showers in the second half of April in comparison to the first half, due to strong daytime heating of land areas which caused thundery showers to fall in the afternoon over most parts of the island.
About half of the island recorded above-normal rainfall, 78 per cent above average. The rainfall at Jurong West was 57 per cent below average.
On Apr 17, a large-scale convergence of winds brought about a spell of thundery showers during the night and pre-dawn hours.
The daily total rainfall of 91.1mm recorded at Sengkang that day was the highest recorded rainfall for April 2022.
“It was generally warm in April 2022. The daily maximum temperature was above 34 degrees Celsius on 13 days. On seven of these days, the daily maximum temperature was at least 35 degrees Celsius,” said NEA.
The highest temperature of 36.8 degrees Celsius was recorded at Admiralty on Apr 1 while the lowest minimum temperature of 22.2 degrees Celsius was recorded at Sembawang on Apr 9.
