Trader consensus on Polymarket reflects tight uncertainty in short-range forecasts for Shanghai's highest temperature on April 6, with China Meteorological Administration models favoring 22°C under persistent cloud cover and light southerly winds limiting solar heating. Leading implied probabilities cluster around 22–24°C as ensemble guidance from ECMWF and GFS shows a spread driven by the exact position of an approaching frontal boundary—slight northward shifts could boost highs to 24°C via warmer advection, while stronger overcast or northerly gusts might cap at 21°C. Early April climatology averages 19°C, but recent mild patterns have elevated expectations; daily CMA updates through April 5 will refine resolution amid typical spring variability.
