Forecast models from agencies like the China Meteorological Administration point to a Shanghai high near 30–31°C on June 19, 2026, amid the East Asian monsoon’s mei-yu (plum rain) regime, which sustains cloud cover, high humidity, and scattered thunderstorms that cap daytime heating. Early June warmth across the Yangtze River Delta has lifted baselines above the 27–30°C climatological average, yet persistent moisture and variable steering patterns create tight uncertainty between these two outcomes. Recent model runs show minor spread in boundary-layer moisture and timing of convective cells, directly supporting the closely matched market-implied odds at 29% and 25.5% while keeping 28°C and 32°C viable depending on exact rainfall timing.
