Trader consensus on Polymarket favors 16°C (38%) slightly over 17°C (30%) for Shanghai's highest temperature on March 27, driven by the latest ensemble forecasts from ECMWF and GFS models projecting mild spring conditions under neutral ENSO influences, with a weak high-pressure ridge over East Asia enabling highs in the mid-teens Celsius. Recent observational data from the China Meteorological Administration shows daytime peaks stabilizing around 14-15°C amid light southerly flows and moderate solar insolation, differentiating 16°C as the central tendency while 17°C accounts for potential warm anomalies from clearer skies or minor advection. Lower probabilities for 15°C (19.5%) reflect downside risks from cloud cover, with model spread highlighting uncertainty typical of 3-5 day outlooks. Key upcoming CMA bulletins and high-resolution runs could sharpen these market-implied odds.
