Trader consensus on Polymarket has locked in at virtually 100% implied probability for a highest temperature of exactly 30°C in Shenzhen on May 12, 2026, driven by official observations from Shenzhen Bao'an International Airport—the designated resolution station—recording this peak via standard whole-degree Celsius measurements. Cloudy skies and light rain throughout the day significantly reduced solar insolation, capping heating despite pre-event forecasts from models like AccuWeather projecting 31–33°C amid typical May humidity and southerly flows. This aligns with Shenzhen's climatological May average highs near 29°C, per historical data from the China Meteorological Administration. Realistic challenges would require rare post-observation revisions from authoritative sources, though none are anticipated as the market has resolved accordingly.
