Recent forecasts from multiple models indicate Shanghai's overnight minimum on August 31 will likely fall between 26–27°C under partly cloudy skies with light southeasterly winds and a modest chance of showers. High humidity and limited nocturnal radiative cooling in the late-summer subtropical regime keep temperatures from dropping further, while the absence of a strong cold front or typhoon influence maintains this range. Market-implied odds align closely with this consensus, with 27°C leading at 42% and 26°C at 30.5%, reflecting traders' assessment of model agreement and typical August climatology where daily lows average near 25–26°C. Updated runs from agencies such as the China Meteorological Administration or ECMWF over the next 48 hours could shift probabilities if cloud cover or wind patterns change.
