Meteorological Service Singapore (MSS) forecasts a daily maximum temperature of 34°C for April 1, 2026, driven by persistent high humidity, moderate winds, and thundery showers expected over southern, western, and central areas in the late afternoon and evening, capping further heating after early peaks reached 34–35°C at stations like Sembawang and MSS. This aligns with model consensus showing limited solar insolation under increasing cloud cover, consistent with Singapore's tropical climatology where April highs typically range 31–34°C amid the inter-monsoon period. Trader sentiment at 99.7% implied probability for 34°C reflects this authoritative guidance and observed conditions as of late afternoon. A realistic upset would require delayed showers and prolonged clear skies enabling radiative warming to 35°C+, though ensemble forecasts deem this unlikely before evening cooldown. Final MSS daily records will resolve the market.
