Trader consensus on Polymarket has converged to a 100% implied probability for a 22°C high temperature in Wuhan on May 8, backed by real-time hourly observations from the official Wuhan Tianhe International Airport station (ZHHH via Wunderground and China Meteorological Administration data), which recorded a midday peak of 22°C amid persistent overcast skies and light northeast winds following rain showers the prior day. Reduced solar insolation from thick cloud cover—evident in 61% relative humidity and dew points around 14°C—has capped surface heating well below May climatological averages of 26–28°C. While inherent measurement uncertainties exist, a challenge to this positioning would require improbable late-afternoon clearing and rapid convective warming before sunset, with final daily maximum confirmation expected from CMA archives within 24 hours.
