Recent forecasts from sources like the China Meteorological Administration indicate Shanghai will see mostly cloudy conditions with light rain or thunderstorms around August 12, limiting daytime heating and supporting the tight market clustering around 29–30°C. High humidity levels near 80% and easterly winds of 30–40 km/h are expected to moderate peak temperatures, while the urban heat island effect and residual warmth from recent highs near 35°C keep 31°C or higher as a plausible outlier if skies clear earlier. Model consensus on precipitation timing and intensity remains the key variable that could shift the daily maximum by 1–2°C.
