Trader consensus on Polymarket closely splits between 17°C (43.5%) and 16°C (41.5%) for Shanghai's highest temperature on March 26, reflecting tight uncertainty in the latest forecast ensembles from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS), which project afternoon maxima in this narrow range amid mild southerly flows. Recent model runs over the past 24 hours show minor divergences due to varying predictions of low-level cloud cover and boundary layer mixing, potentially capping peaks at 16°C or allowing slight additional heating to 17°C under clearer skies. Shanghai's late-March climatology averages highs near 14°C, but current upper-air patterns favor above-normal warmth; traders await China Meteorological Administration updates and real-time observations from Pudong station for resolution as the date unfolds.
