Traders overwhelmingly back 17°C (43.5%) and 18°C (32.5%) for Shanghai's highest temperature on March 22, driven by consensus from leading global models like ECMWF and GFS, which project daytime highs of 16–19°C amid mild southerly flows and residual winter chill. Recent observations from Shanghai Pudong station show overnight lows near 10°C on March 21, supporting peak afternoon readings in this range under partly cloudy skies with light winds, per China Meteorological Administration updates. Spring climatology favors these outcomes, with March 22 historical averages around 15°C but a warming trend boosting upper probabilities; model ensembles indicate low risk of extremes beyond 20°C due to frontal boundaries limiting heat advection.
