Recent short-range forecasts from regional models indicate Singapore's minimum temperature on September 12 will most likely fall between 26–27°C under prevailing southwest monsoon conditions, with scattered showers and southeasterly winds limiting nocturnal radiative cooling. Persistent regional haze from Sumatran fires and elevated humidity near 75–85% further stabilize overnight lows near climatological norms, while any clearer intervals could allow modest drops toward 25°C. Trader sentiment remains split between the 22°C-or-below and 32°C-or-higher brackets because model runs continue to diverge on cloud cover and rainfall timing, both of which directly influence the daily minimum recorded at official stations such as Changi. With resolution imminent, the next 48-hour observational updates from Singapore’s Meteorological Service will determine whether the minimum aligns with the narrower 25–28°C cluster or deviates under unexpected convective activity.
