Recent forecasts from sources like TimeandDate and AccuWeather indicate Shanghai's minimum temperature on August 19 will likely fall between 25–27°C, driven by persistent subtropical high pressure, elevated humidity near 70–80%, and limited overnight radiative cooling under partly cloudy skies. Model consensus shows highs near 32–34°C with scattered showers or thundershowers possible, which moderate temperature drops compared to clearer nights. These conditions align with typical mid-August climatology for the region, where daily lows average 25–26°C, keeping the 26–27°C outcomes dominant in trader positioning. Updated model runs and local meteorological briefings over the next 12–24 hours represent the primary near-term catalysts that could shift implied probabilities if cloud cover or precipitation deviates.
