Current forecasts from meteorological agencies and models indicate an overnight low near 27°C in Shanghai on August 10, 2026, driven by persistent subtropical summer conditions, high humidity, and urban heat-island effects that limit nocturnal radiative cooling. Overcast skies and scattered thunderstorms expected through the period further moderate temperature drops by trapping heat and adding moisture, aligning with climatological August baselines of 25–28°C minima. Recent model runs show tight consensus around 26–28°C with minimal deviation from ongoing warm, moist air masses and no incoming cold fronts. Trader-implied probabilities heavily favor 27°C as the mode because these atmospheric patterns have produced similar stabilized lows in prior days, though minor forecast revisions from additional precipitation could still shift the exact minimum within the narrow range.
