Recent official forecasts from agencies including the Hong Kong Observatory and regional models project Shanghai's minimum temperature on August 24 holding at 27°C under cloudy to partly cloudy skies with high humidity and light easterly winds. This aligns with typical late-August subtropical patterns, where urban heat retention and elevated dew points limit overnight radiative cooling, keeping lows near seasonal averages of 25–27°C rather than dipping lower. The overwhelming market consensus at 27°C reflects traders incorporating these stable conditions and the day's proximity to resolution, which reduces forecast uncertainty. A realistic shift toward 26°C would require unexpected clear skies or stronger winds enhancing cooling, while 28°C could occur only if daytime heat lingers unusually late into the night.
