35°C temperatures on a few days
Several nights in the next two weeks are expected to be warm and humid, with temperatures staying above 29°C, MSS said.
During the day, maximum temperatures should be around 34°C on most days.
On a few days, though, the temperature may hit 35°C.
Thundery showers on some days
Thundery showers will still fall over parts of the island on some days, MSS said.
But these are likely to be localised and of short duration, occurring in the late morning and afternoon.

On a few days, widespread thundery showers and gusty winds will take place in the pre-dawn hours and morning.
They will be brought about by Sumatra squalls — a weather phenomenon caused by the difference in temperature between land and sea.
For this period, the total rainfall should be “near average” over most parts of the island.
Southwest Monsoon coming in early June
The drier weather is attributed to the Southwest Monsoon, which will set in over the surrounding region in early June.
The Southwest Monsoon is generally drier than other times of the year, and typically lasts till September.
As it arrives, winds are forecast to strengthen and blow over Singapore from the southeast or southwest.
Below-average rainfall in 2nd half of May
Over the second half of May, localised short-duration thundery showers fell over parts of the island on several days, but most parts of Singapore experienced below-average rainfall.

However, widespread thundery showers fell over Singapore in the late morning and early afternoon on 18 May, due to the passage of a Sumatra squall.
On that day, a daily total rainfall of 78.6mm was registered at Sembawang — the highest rainfall recorded for the two-week period.
Above-35°C temperatures on several days
As expected, the fortnight was “warm”, MSS said.
On several days, daily maximum temperatures of above 35°C were experienced.
In Paya Lebar, the mercury even went up to 36.2°C on 24 May.
This was the highest daily maximum temperature for the two weeks.
