Ensemble weather models from NOAA's GFS and ECMWF, alongside forecasts from AccuWeather and Weather.com, peg Shanghai's highest temperature on March 22 at 17-18°C, driving trader consensus with 45.5% implied probability for 17°C and 35.5% for 18°C. Recent mild southerly air flows have elevated early spring temperatures above the March historical average of 12-15°C, with no major cold fronts anticipated per China Meteorological Administration updates. Preliminary observations from March 21 show daytime highs near 16°C, aligning with model projections that factor in urban heat islands and sea-level pressure patterns, positioning 19°C (13.5%) as a plausible outlier amid low volatility in short-range forecasts.
