Current forecasts for Singapore on September 26 indicate daily maximum temperatures of 31–33°C under prevailing southwest monsoon conditions, with localized afternoon thundery showers expected to influence peak readings. Model consensus from sources including the Meteorological Service Singapore points to partly cloudy skies and southeast winds, keeping values near the September climatological average of 31.6°C while allowing brief periods of stronger insolation that could push the official high to 33°C. The tight market split between 32°C and 33°C reflects uncertainty in shower timing and cloud cover, which can suppress or permit higher readings; probabilities drop sharply beyond 34°C given the low likelihood of clear, stable conditions needed for greater warming. Official NEA observations tomorrow will resolve the market based on the highest recorded temperature across stations.
