Trader consensus on Polymarket closely splits between 26°C (30%) and 27°C (30.5%) for Wuhan's highest temperature on April 17, driven by ensemble forecasts from the China Meteorological Administration (CMA), ECMWF, and GFS models converging on a daytime high near 27°C at Wuhan Tianhe International Airport—the official resolution station. Recent persistent rain showers through April 16 suppressed highs to around 22°C, but high-pressure ridging and reduced cloud cover in latest runs signal stronger solar insolation and potential afternoon peaks in the mid-to-upper 20s. Differing cloud timing and boundary layer mixing create the razor-thin uncertainty differentiating 26°C from 27°C, with overnight model updates and hourly airport observations poised to sharpen probabilities before resolution. Historical mid-April averages hover at 22–24°C, underscoring this forecast's warmer tilt.
