Trader consensus favors a 29–30°C peak for Shanghai on August 13, as ensemble forecasts from global models indicate persistent subtropical high pressure with modest humidity and limited convective cloud cover moderating daytime heating. August climatology for the region typically produces mean daily maxima near 31°C under East Asian monsoon influence and urban heat-island amplification, yet recent runs show small spreads tied to sea-breeze timing and possible weak frontal moisture. These factors create the tight 29–30°C bracket, with lower probabilities assigned to 31°C or higher only if clearer skies and stronger insolation develop. China Meteorological Administration updates over the next 48 hours will narrow the range ahead of the daily maximum observation window.
