Trader consensus on Polymarket assigns a 100% implied probability to 29°C as Singapore's highest temperature on May 15, 2026, driven by official National Environment Agency (NEA) observations at Changi Airport—the market's sole resolution station—peaking at 29°C amid widespread thundery showers and cloudy skies that sharply limited solar insolation and daytime convective heating. NEA reports confirm heavy rainfall totals exceeding 80 mm in areas like Pasir Ris, aligning with inter-monsoon conditions forecasted for May's first half, where frequent showers have moderated early-month highs from 35°C+ to mid-30s or below. Historical May daily maxima average 31–33°C, but today's persistent cloud cover suppressed potential intensification. A realistic challenge would require an upward data revision from late-evening clearance or measurement adjustment, though NEA's real-time station logs through evening make this improbable. Final historical records update expected by month-end.
