Official temperature observations from Singapore’s meteorological authorities have locked in a daily maximum of 33°C on September 29, aligning with model consensus from sources like NEA and Changi Airport data showing afternoon peaks near that threshold amid partly cloudy skies, easterly winds, and elevated haze. This matches typical late-September climatology for the region, where daily highs average 31–33°C, following a brief heat spike that produced a joint September record of 35.8°C at Woodlands on the 26th. The near-certain market outcome reflects verified station readings rather than forecasts; revisions to official maxima or station-specific anomalies remain the only realistic variables that could alter resolution.
