Recent forecasts for Shanghai indicate highs in the mid-30s Celsius on July 25, with model consensus reflecting the ongoing summer heatwave that produced readings above 38°C earlier in the month and above the 1991-2020 baseline. Monsoon-driven moisture and potential thunderstorm activity across East Asia through July 26 introduce variability that could limit further intensification via cloud cover or precipitation, keeping 34–36°C as the tightly clustered outcomes. Shanghai’s urban heat island effect and high humidity amplify daytime maxima, while resolution hinges on official station measurements. Updated numerical weather prediction runs from agencies like the China Meteorological Administration will provide the next key data points for refining these probabilities.
