Trader consensus on Polymarket heavily favors a Shanghai low temperature of 11°C (42% implied probability) on May 1, reflecting China Meteorological Administration (CMA) forecasts and global models like ECMWF and GFS, which project 11-12°C amid a persistent cool air mass from recent northerly winds. Late-April observations recorded lows near 12-13°C under clear skies promoting radiative cooling over the Yangtze Delta, anchoring these leading outcomes while pricing 10°C at 28.5% on potential deeper nocturnal cooling. Model divergence persists on increasing cloud cover from an approaching frontal system tied to Labor Day holiday weather, introducing upside risk toward 13°C. This setup deviates from early-May climatological lows around 15-16°C; watch CMA evening updates on April 30 for refinements.
