The cold weather in Singapore is expected to continue for the next few nights because of the wetter weather and the monsoon conditions in the first 2 weeks of this month.
Associate Professor Koh Tieh Yong from SUSS, a weather and climate scientist, said that the current cold conditions are influenced by La Nina, which is a natural climate phenomenon which brings about wetter weather and enhances the north east monsoon winds in Singapore.
The Meteorological Service Singapore (MSS) said on 31 January that more thundery showers were to be expected in the first fortnight of February, as compared to the last fortnight of the month.
Professor Koh said that the cool temperature is likely to remain for one or more nights whether the rain persists or not, due to the arriving air having been pre-chilled over the South China Sea, by the evaporating rain.
