Official observations from Singapore's meteorological service recorded a daily maximum air temperature of 33°C on September 6, aligning with the market's near-certain consensus. Persistent southwest monsoon conditions, fair and occasionally windy weather, and below-average rainfall supported typical seasonal warmth, with model guidance and historical September baselines showing frequent peaks near this threshold. Feels-like temperatures exceeded 33°C due to humidity, but resolution hinges on official dry-bulb readings. Minor upward revisions from additional station data or localized variability could theoretically alter outcomes, though current verified measurements leave little room for deviation.
