Trader consensus on Polymarket heavily favors Shanghai's highest temperature on March 27 at 16°C (41.5%) or 17°C (36.0%), reflecting the latest forecast model ensembles from the China Meteorological Administration (CMA) and ECMWF, which project afternoon peaks in this narrow range amid mild spring conditions. Recent model runs show a tight spread of 1–2°C, differentiated primarily by varying predictions on diurnally driven warming under partly cloudy skies and light northerly winds capping intensity after a passing cold air mass earlier in the week. Historical March averages hover around 15°C, but an ongoing warming trend from East Asian high-pressure ridging has nudged expectations upward. Key uncertainty stems from precise timing of peak solar heating and any convective activity; watch CMA's evening update and initial observations for potential shifts before resolution based on official station data from Xujiahui Observatory.
