Trader consensus on Polymarket closely splits between 19°C (33.5%) and 20°C (29.5%) for Shanghai's highest temperature on April 18, reflecting tight uncertainty in recent forecast model runs from GFS, ECMWF, and China Meteorological Administration ensembles, which show a 1–2°C spread centered near 19.5°C at the resolving Shanghai Pudong International Airport station. Key differentiators include variable afternoon cloud cover reducing solar insolation for 19°C versus partial clearing and urban heat island effects pushing to 20°C, amid a mild post-frontal air mass typical of mid-April climatology with historical highs averaging 19°C. Sea breeze timing and light winds add volatility; hourly observations from official monitors will resolve tomorrow amid inherent short-range forecast divergence.
