Recent forecasts for Shanghai indicate minimum temperatures on July 1 centered around 23–26°C amid the transition out of the East Asian monsoon’s plum rain period, when increased cloud cover and humidity typically moderate nighttime radiative cooling. Model consensus from sources like AccuWeather and regional outlooks points to light rain or overcast conditions that limit temperature drops, while any clearer intervals or reduced moisture could allow lows near 22°C or below. This scientific uncertainty—driven by short-term variability in steering patterns, local urban effects, and precipitation timing—explains the tightly clustered market-implied probabilities across the 22–26°C range, with lower odds on extremes reflecting historical July baselines and limited deviation potential just 48 hours out.
