Recent forecasts from sources including the Met Office and timeanddate indicate Shanghai daytime highs of 30–33°C on August 21, with possible thundershowers or broken cloud cover that could limit peak temperatures through reduced solar heating and evaporative cooling. Trader consensus clustering around 30–31°C reflects typical late-summer conditions in the region, where high humidity (often 70–90%) and residual moisture from earlier Typhoon Dolphin activity favor scattered convection over intense clear-sky heating. Key variables include steering patterns that may sustain onshore flow or trigger additional showers, versus any brief clearing that could push readings toward 32°C. Historical August averages near 32°C provide context, but model consensus on precipitation timing will determine whether the daily maximum settles at the lower or upper end of the narrow range.
