Singapore weather forecast: Showers, warm nights in June first half

The total rainfall for the first fortnight of June is forecast to be below average over most parts of the island.

The daily maximum temperatures during this period are likely to range from 33 deg C to 34 deg C. On some days, the daily maximum temperature may reach around 35 deg C when there is less cloud coverage.

Nights are likely to be warm and humid, with temperatures remaining above 28 deg C on several nights, said the Met Service.

In a review of the past fortnight, the Met Service said thundery showers fell over parts of the island in the afternoon on most days. The Sumatra squall also brought thundery showers and gusty winds over Singapore in the pre-dawn and morning hours on a few days.

The last two weeks of May saw inter-monsoon conditions prevailing over the island and the surrounding region, with winds generally light and variable in direction, added the weatherman. On some days, the winds shifted to blow from the south-east or south-west, it said.

May 16 saw the highest rainfall recorded in the second fortnight of the month, with 102.4mm of rainfall recorded in Tuas South. That morning saw heavy thundery showers over many areas, brought about by the regional convergence of winds, said the Met Service.

The second half of May was warm, with daily maximum temperatures during that period above 33 deg C on most days. The highest daily maximum temperature of 35.7 deg C was recorded in Ang Mo Kio on May 20.

During this period, the eastern, southern and south-western parts of Singapore recorded above-average rainfall, while the other parts recorded mostly below-average rainfall, said the Met Service.

The area around Sentosa registered 94 per cent above average rainfall, while the area around Jurong West registered rainfall levels 34 per cent below average.
