Forecast models from sources including Weather Underground and MetaWeather consensus on a daily maximum of 33°C for Singapore on September 29, 2026, aligning with observed afternoon readings near 32–34°C under partly cloudy skies with easterly winds. This matches the typical September average high of 31–32°C and recent National Environment Agency guidance for warm conditions with highs at or above 33°C in the month's second half. Trader consensus at 100% implied probability for 33°C reflects these verified observations and limited model spread, though scattered showers or localized cooling could still cap the peak below that threshold if convective activity intensifies unexpectedly before official station reports finalize.
