Trader consensus on Polymarket overwhelmingly backs a highest temperature of 31°C in Singapore on May 9, 2026, reflecting real-time observations from the National Environment Agency (NEA) stations amid persistent afternoon thundery showers that capped solar heating and convective potential. The Meteorological Service Singapore's April 30 fortnightly outlook anticipated 33–35°C maxima during the inter-monsoon period, but widespread cloud cover and light rainfall—forecast for most days in early May—have aligned outcomes with May's climatological baseline of 31–32°C daily peaks at Changi, based on long-term records. This skin-in-the-game positioning leaves negligible room for higher readings, though an improbable late-evening clearing with gusty winds could enable a brief spike; official daily records update by May 10 will confirm resolution.
