Trader consensus on Polymarket favors a Shanghai high temperature of 18°C (28.5% implied probability) or 17°C (23.5%), reflecting the latest forecast model runs from ECMWF and GFS, which project daytime highs in the mid-to-upper teens Celsius amid moderating northerly winds following a recent cold front. Current upper-air patterns show a weakening trough over eastern China, allowing gradual warming under partly cloudy skies, though lingering moisture could cap peaks via increased cloud cover or shallow inversions. Historical March data for Shanghai indicates average highs near 16°C with a standard deviation of 3–4°C, amplifying uncertainty; differentials hinge on exact timing of diurnal heating and any late-afternoon sea breeze. China Meteorological Administration updates expected today could refine these odds ahead of the March 29 observation.
