Official observations from Singapore's Meteorological Service at the Changi Climate Station—the reference site for daily records—confirm a peak temperature of 33°C mid-afternoon on May 10, 2026, driving the market's 100% implied probability for this outcome. Inter-monsoon conditions with light winds and afternoon thundery showers triggered convective activity, capping solar heating before typical peak times (2-4 PM local), as shown in NEA real-time data and forecast models. Trader consensus aligns with this skin-in-the-game assessment, given historical May highs averaging 31-33°C and minimal diurnal range in Singapore's tropical climate. A challenge would require improbable late-evening clear skies and renewed insolation post-sunset (around 7:07 PM SGT), with final NEA records expected by month's end.
