Wettest August day on record by a large margin in Singapore
August 24 2021:
The Singaporean station of Mandai saw some 247.2 mm of rain on Tuesday, the highest daily rainfall at any station in Singapore in August on record by a large margin breaking the previous record of 181.8 mm at Changi Station on August 22 1983 with daily rainfall records in the city state extending back to 1929.
However, the intense rainfall was relatively localised, for example the rest of Singapore saw much less rainfall and Singapore is a very small country, so it is like one suburb seeing mm of rain and other suburbs seeing less than 20 mm of rain.
Flash floods occurred in areas of heavy rainfall and rainwater even flooded some shopping malls.
Temperatures even dipped to 21.3°C at Newton at 11:13 AM at due to the heavy rain.
"Singapore experienced a few spells of widespread moderate to heavy thundery showers from around 4.30am today (24 Aug 2021). The showers were due to prevailing winds from the south and southwest, converging around the vicinity of Singapore.
The rainfall was heaviest over the northern and western parts of the island. The highest daily total rainfall recorded as of 12 noon today was 239.8mm and 226.2mm at Mandai and Bukit Panjang respectively. This is the highest daily total rainfall for Aug 2021 to date, and has surpassed the record highest daily total rainfall of 181.8mm (at Changi on 22 Aug 1983) for Aug. The highest rainfall intensity over 60 minutes was 84.8mm recorded at Mandai (as of 12 noon today). For comparison, the highest 60-minute rainfall intensity during the heavy rain last Fri (20 Aug) was 95.8mm, recorded at Choa Chu Kang.
The lowest temperature as at 12 noon today was 21.3 deg C recorded at Newton.
The rainy weather in the past few days was due to strong convergence of winds over Singapore and the surrounding vicinity. The equatorial Pacific Ocean is currently in a neutral state with no developing El Nino or La Nina. The Indian Ocean Dipole is currently in a negative state which typically brings more rainfall to the region, and could be a contributing factor to the recent weather we have been experiencing." the National Environment Agency said in a statement posted on Facebook at 3:58 PM.
