Singapore, 16 June 2020 – According to the Meteorological Service Singapore (MSS), the current wet weather is expected to continue in the second half of June 2020. During this period, thundery showers are expected on most days and this could bring a slight easing of the warm temperatures felt in recent weeks.

2          The prevailing Southwest Monsoon is forecast to persist for the rest of June 2020 and extend to end September 2020. For the rest of this month, the low-level winds over Singapore are forecast to blow from the southeast or south, and shifting to blow from the southwest or west on some days. 

3          In the second fortnight of June 2020, the monsoon rain band is expected to remain close to the equatorial region. On many days in the fortnight, short-duration moderate to heavy thundery showers can be expected between the late morning and early afternoon, and extending into the late afternoon on a few days. The convergence of winds in the surrounding vicinity could also bring thundery showers on a few nights. Widespread thundery showers with gusty winds due to the passage of Sumatra squalls are forecast on two or three days between the predawn hours and morning. Overall, the rainfall for June 2020 is forecast to be above-average over most parts of the island.

4          The wetter weather expected in the second half of June 2020 will help to slightly ease the warm and humid conditions felt in recent weeks. The daily temperature on most days is forecast to range between 25°C and 33°C. There could still be a few warm days where the daily maximum temperature could reach a high of around 34°C.

REVIEW (1 – 15 June 2020)

6          In the first fortnight of June 2020, Southwest Monsoon conditions prevailed over Singapore and the surrounding region.  The prevailing winds blew from the southeast or south on most days, and from the southwest or west on a few days.

7          During the first two weeks of June 2020, most of the thundery showers occurred in the afternoon due to strong solar heating of land areas. There were a few nights where moderate to heavy thundery showers fell over the island due to convergence of winds in the region. On 13 June 2020, widespread moderate to heavy thundery showers fell over the island between the predawn hours and morning. This was due to the convergence of winds over the region under the indirect influence of Tropical Storm “Nuri” as it intensified over the South China Sea. The daily total rainfall of 84.0mm recorded at Jurong West that day was the highest daily total for the first half of June 2020.

8          The first half of June 2020 was less warm compared to the last two months due to more days of rain. The daily maximum temperature ranged between 31°C and 34°C on many days and reached 35°C or more on a few days. The highest daily maximum temperature of 35.6°C was recorded at Admiralty on 2 June 2020. There were a few warm nights where the night-time minimum temperature was around 28°C over the eastern, southern and western parts of the island.

9          Almost all parts of the island received above average rainfall in the first fortnight of June 2020. The highest anomaly of 155 per cent above average was recorded at Jurong West. The anomaly was lowest at Admiralty at four per cent below average.
