Recent forecasts from meteorological agencies point to a daily maximum of 31–32°C in Shanghai on August 24 under partly cloudy skies, light southeast winds, and modest humidity typical of late-August subtropical conditions. Persistent easterly flow and scattered showers have limited daytime heating in recent days, aligning with climatological averages near 31°C and keeping stronger warming unlikely. Model consensus favors this range over 33°C or higher, though minor variations in cloud timing or wind speed could shift the peak by 1°C and explain the tight market split between the leading outcomes. Traders appear to weigh official guidance and historical analogs heavily as resolution nears.
