Latest GFS and ECMWF ensemble forecasts project Shanghai's highest temperature at Pudong International Airport on April 4 around 20-22°C, aligning with trader consensus favoring 21°C at 41% implied probability, followed by 22°C at 22.5%. This positioning reflects a rebound from today's cooler, rainy conditions—highs near 16°C under a passing frontal system—with models anticipating clearing skies, light southerly winds, and ample solar heating in the subtropical monsoon climate. Early April climatology averages 17-19°C highs, but neutral ENSO patterns support mild above-normal warmth. Ensemble spread of 2-3°C underscores uncertainty from cloud timing or gusts; watch afternoon 12Z model runs and China Meteorological Administration updates for refinements ahead of resolution.
