Trader consensus on Polymarket heavily favors a Shanghai high of 15°C at 35% implied probability, driven by the latest ECMWF and GFS ensemble forecasts converging on 14.5–15.5°C for March 23 amid partly cloudy skies and light southerly winds enhancing mild advection from the south. Differentiating factors include potential for 16°C (25.5%) if solar insolation exceeds model averages under reduced cloud cover, versus 14°C (22.5%) should an incoming low-pressure trough increase overcast conditions and suppress daytime heating. Historical March averages hover around 13–14°C, but recent urban heat island effects and a warming spring trend bolster the tighter cluster above norms, with uncertainty tied to 24-hour model updates from the Shanghai Meteorological Bureau.
