Trader consensus on Polymarket assigns near-certainty (100%) to a highest temperature of 34°C at Singapore's Changi Airport station on April 30, 2026, reflecting real-time observational data from the Meteorological Service Singapore showing peak readings capped at that level amid persistent afternoon thundery showers under inter-monsoon conditions. These showers and associated cloud cover limited solar heating, aligning with the agency's fortnightly outlook forecasting daily maxima of 33–34°C for late April, with 35°C possible only on isolated days—none realized here. Historical April climatology supports this, as urban heat islands rarely push beyond 35°C without prolonged clear skies. Final official daily records, typically published shortly after midnight, could confirm; a rare late-afternoon clearing might prompt minor revisions, though model ensembles indicate low likelihood.
