It’s Going to be Wet & Humid for the First Half of May

April saw wet and humid weather, which many of us complained about.

Unfortunately, the weather is expected to continue into the first half of May 2023.

Groan.

Wet and Humid Weather Expected

According to the Meteorological Service Singapore (MSS), you can expect short thundery showers over parts of Singapore in the afternoon on most days. 

The showers could extend into the evening on a few days. 

This phenomenon is due to the strong daytime heating of land areas.

The daily maximum temperature is expected to reach 34 degrees Celsius on most afternoons, so wear lighter clothes and bring an umbrella.

Since the weather can’t make up its mind, it’s better to be prepared for anything.

A few days will see the temperature reaching 35 degrees Celsius.

Overview of April’s Weather

On 20 April 2023, some parts of Singapore saw heavy thundery showers and strong winds in the morning.

The heavy thundery showers resulted from a Sumatra squall, a line of thunderstorms originating over Sumatra or the Strait of Malacca.

Westerly winds cause Sumatra squalls to move towards Singapore.

If you remember sweating buckets, it’s probably because the daily maximum temperature was above 34 degrees Celsius on most days.

The highest daily maximum temperature recorded in April 2023 was 36.1 degrees Celsius.

It was Woodlands that experienced this high temperature on 14 April 2023.

Why is May so Wet and Humid?

In general, May is one of the warmest months of the year.

This is primarily due to inter-monsoon conditions, which usually prevail from late March to May and October to November.

While Singapore is humid all year round, it feels especially bad in May.

During inter-monsoon periods, Singapore experiences light and variable winds that interact with land and sea breezes.

Unfortunately, the winds aren’t strong enough to ease the humidity, causing it to feel hotter than it actually is.

Will Singapore Hit 40 Degrees Celsius?

The adverse effects of climate change aren’t helping to beat the heat.

The mean surface air temperature has risen by an average of 0.35 degree Celsius between 1948 and 2023.

This begs the question: Will Singapore hit 40 degrees Celsius anytime soon?

According to the National Environment Agency (NEA), it’s “unlikely” that Singapore will hit 40 degrees Celsius in the coming weeks. 

This comment came as a response to a text message that has been circulating, warning Singaporeans of an incoming heatwave between 40 and 50 degrees Celsius.

In a Facebook post, NEA wrote, “Although we have been experiencing warmer days in recent weeks, the temperatures were not record-breaking.”

Singapore’s highest temperature recorded thus far is 37 degrees Celsius on 17 April 1983.

However, this doesn’t mean we’re completely off the hook.

In 2019, TODAY reported that according to scientists, Singaporeans could face temperatures of 40 degrees Celsius on some days by 2045.

In an interview with TODAY, Dr Muhammad Eeqmal Hassim, a senior research scientist at the Centre for Climate Research Singapore, said, “It won’t be a one-off event. There’ll be some days starting from as early as 2045.”
