Hot and humid weather continues for the rest of April, with frequent showers and lightning most days


Thundery showers expected in the afternoon, but below-average rainfall for April

While the weather this month has been generally warm for Singapore, the April showers have also fallen heavily.

This means that having an umbrella is essential, even if we dress lightly for the hot weather.

The hot and humid weather is now expected to continue for the remainder of April.

Thundery showers will come with frequent lightning on most days.

Inter-monsoon conditions to stay until May

In a weather advisory on Thursday April 14, the Meteorological Service of Singapore (MSS) said the current inter-monsoon conditions will go nowhere for the rest of this month.

They will be tested in Singapore and the surrounding region until at least May.

So, as usual in these conditions, short-lived moderate to heavy thundershowers are likely to occur in the afternoon.

Most days they will be accompanied by frequent lightning, they added.

Sumatra squalls can bring morning showers

As is also typical during the inter-monsoon period, prevailing winds will be light and variable in direction.

Over the next two weeks they will occasionally blow from the southwest or west.

The convergence of prevailing winds from these directions could lead to the development of Sumatran squalls over the Strait of Malacca early in the next fortnight, the MSS said.

These squalls will move east towards the South China Sea, meaning they could bring widespread thundery showers and gusty winds before dawn and into the morning.

This should happen in a few days.

Evening showers too

If this is not enough, showers will also occur in the evening for a few days.

This will happen when the afternoon thundershowers become intense.

This will cause them to continue until early evening, according to the MSS.

However, despite the possibility of rain in the afternoon, morning and evening, rainfall in April is expected to be below average for most parts of Singapore.

Maximum temperature around 34°C

The hot conditions encountered in the first half of April will follow us again in the second half.

Most days, daily highs should be around 34°C.

However, the daily minimum temperature can drop to around 23°C when it rains for 1 or 2 days.

Below average rainfall in April

While rainfall in March was above average, rainfall in April has so far been well below average.

While the wettest area was Punggol, the rainfall recorded was only 22% above average. It did, however, experience the highest daily rainfall totals over the two weeks – 70.2mm on 6 April.

The rest of Singapore saw below average rainfall, with the driest area being Jurong West, where it was 87% below average.

When it rained, it mostly fell in the late morning and afternoon, although on some days Sumatran squalls brought downpours and high winds in the early morning hours on some days.

A sequel to a lethal combination

The humid but warm weather expected in the rest of April is simply a continuation of the situation of the past 2 weeks.

So, Singaporeans should have no problem getting used to the deadly suit and dressing appropriately.

If you have a good camera, you can also hope to take a good picture of the lightning bolts which will surely be seen daily.
