Will the highest temperature in Shanghai be 18°C on April 3?

Analysis

Ensemble forecasts from ECMWF, GFS, and CMA consistently project Shanghai's highest temperature on April 3, 2026, to be between 15-17°C. This aligns with trader consensus, where outcomes for 16°C and 17°C collectively hold over 70% implied probability. The 18°C outcome currently stands at a low 14.0%. A lingering cool northerly air mass, persistent cloud cover, and 40-50% chance of moderate rain are expected to limit solar insolation and daytime heating, thereby suppressing temperatures below the early April climatological average of 18°C. While the climatological average is 18°C, current conditions heavily bias against reaching this temperature. Given the strong convergence of weather models, current conditions, and market probabilities against 18°C, a 'NO' prediction is strongly supported as the market closes very soon.
