Trader consensus on Polymarket assigns a 58.5% implied probability to a 15°C high temperature in Shanghai on March 21, driven by the latest ensemble forecasts from ECMWF and GFS models converging on 14-16°C peaks amid recovering conditions post-recent cold front. Shanghai's March climatology features average highs of 13-15°C, with current surface observations showing daytime maxima rebounding from 10-12°C lows due to southerly winds and enhanced solar insolation. China Meteorological Administration updates confirm mild stability, low pressure gradients, and minimal convective activity, elevating 16°C (24%) as runner-up while relegating colder or warmer extremes below 10% amid low model spread.
