About this Market

Recent model consensus and Singapore's Meteorological Service outlook point to southwest monsoon conditions bringing localized thundery showers on September 20, which typically cap daily maxima through afternoon cloud cover and rainfall. Official guidance indicates temperatures most likely between 33–34°C on typical days in the period, though showers often moderate peaks below that threshold. Historical September averages hover near 31°C, with recent early-month readings reaching 35.3°C only under clearer skies. These factors align with trader emphasis on 32–33°C outcomes while leaving limited room for brief spikes to 34°C or higher if convection remains suppressed. Updated short-range forecasts and real-time observations will refine the final reading before market resolution.
