A monsoon surge in the South China Sea that is forecast to persist over the next few days saw the temperature dip across parts of Singapore yesterday to 22.8 deg C.
This is below an earlier estimated minimum temperature of 23 deg C.
And the weather is predicted to get even cooler in the next few days, with the temperature falling to as low as 22 deg C, according to a Facebook post by the National Environment Agency (NEA).
Yesterday, a temperature of 22.8 deg C was recorded between 6pm and 7pm in areas such as Changi, Newton and Ang Mo Kio by the Meteorological Service Singapore.
It estimates overcast and windy conditions with moderate to heavy rain over Singapore for the next few days. The daily temperature during this period is expected to range between 22 deg C and 28 deg C.
Intense rainfall on Monday morning saw flash floods in nine locations in eastern Singapore.
National water agency PUB said that the wet weather conditions, due to the prevailing north-east monsoon, were aggravated by the development of a Sumatra squall over the Strait of Malacca which moved eastwards, affecting Singapore.
