Trader consensus on Polymarket assigns 100% implied probability to a highest temperature of 34°C in Singapore on April 1, 2026, backed by real-time National Environment Agency (NEA) observations showing peaks around 33-34°C at key stations like Changi Meteorological Station—the likely resolution reference—amid persistent afternoon thundery showers under emerging inter-monsoon conditions. These light winds and cloud cover capped intensities below recent late-March highs of 35.4°C at Sembawang on March 30, aligning with NEA's fortnightly outlook forecasting daily maximums of 33-35°C during this wetter period. While climatological norms for equatorial Singapore support highs near 33°C in April, elevated baseline heat from recent ENSO-neutral transition reinforces warmth; a late-evening clear spell or measurement revision at Changi could challenge this, though probabilities for 35°C or higher remain negligible as the day progresses. Final NEA daily records expected soon.
