About this Market

Recent official forecasts from agencies and models project an afternoon high of 32–33°C for Singapore on September 4 under mostly sunny to partly cloudy skies with southeasterly winds and low rain chances. This aligns with prevailing southwest monsoon conditions that favor fair weather and typical equatorial humidity levels around 50–70%, keeping temperatures near seasonal norms rather than pushing into the mid-30s. Historical September maxima average near 31–32°C, and the absence of unusual atmospheric patterns or haze escalation supports the market’s strong emphasis on 33°C (64% implied probability) over cooler or hotter outcomes. Updated model runs closer to the date will refine exact peak readings.
