The second half of July 2019 is going to be wetter.

The Meteorological Service Singapore said on Tuesday, July 16 that more rain with thundery showers can be expected.

Why?

This is due to large scale wind convergence over Singapore and the region on two to three days.

Localised thundery showers for short periods of time in the late morning and early afternoon could also take place.

Daily maximum temperature

The daily maximum temperature can range between 31.1°C and 34.5°C.

The highest daily maximum temperature recorded at Pulau Ubin on July 6 was 34.5°C.

A few warm 28°C nights have already been experienced, especially over the south-eastern part of the island.

Nights will be warm

The daily temperature for the rest of July is forecast to range between 25°C and 33°C.

The daily maximum temperature could hit 34°C on some days.

Some nights will be warm and humid with temperatures of around 28°C.

South-east winds are likely to bring warm and humid air from the sea.

Rainfall still below average

But despite the burst of wet weather, July's rainfall is likely to be slightly lower than usual.

Below-average rainfall was recorded throughout the island in the first half of the month.

Most of the rain fell in the first week of July.

Thundery showers occurred for short periods of time in the late morning and early afternoon.

This was due to strong solar heating of land areas and large-scale convergence of winds in the surrounding vicinity.

July 8 recorded a daily total rainfall of 51.6mm at Mandai -- the highest recorded in July so far.

Dry and occasional windy conditions

The south-west monsoon conditions are forecast to continue for the rest of July, and persist until October.

Generally dry and occasional windy conditions will be brought to Singapore and the surrounding region in the next week.

Warm and humid air is blown in from the sea by the prevailing south-easterly winds.
