Singapore's equatorial location and prevailing southwest monsoon conditions typically limit overnight radiative cooling, keeping minimum temperatures elevated amid high humidity. The Meteorological Service Singapore's mid-August advisory highlighted warm, humid nights across the second half of the month, with minima expected to remain above 27°C on most days amid drier regional patterns and occasional thundery showers. Recent observations show daily lows clustering near 26–27°C, while model guidance for August 25 points to overnight values around 26–28°C depending on cloud cover and wind. These factors concentrate trader-implied probability on 27–28°C outcomes, reflecting the consensus that sustained moisture and limited clear-sky cooling will prevent a deeper drop, though localized variations or unexpected showers could still shift the recorded low.
