Latest forecasts from meteorological agencies indicate a daily maximum temperature in Shanghai of 31–32°C on August 25, driven by typical late-summer subtropical conditions with moderate humidity around 60–75% and scattered cloud cover limiting peak solar heating. Regional models show easterly flow and possible sea-breeze effects moderating extremes, consistent with historical August averages near 31°C and no active heatwave or strong high-pressure system intensifying readings. Trader consensus aligns closely with these outputs, assigning over 90% combined implied probability to 31°C or 32°C while discounting 33°C or higher due to limited intensification potential ahead of the resolution window. Updated model runs overnight will refine the final observed high from official stations.
