Recent forecasts from meteorological services indicate Shanghai's overnight low on August 13 will likely settle near 25–26°C amid typical subtropical summer conditions, with variable cloud cover, light rain, and minimal wind. Model consensus highlights modest cooling from daytime highs around 31–34°C due to high humidity and urban heat retention, aligning with climatological baselines for mid-August where average lows range 24–27°C. Minor forecast revisions from agencies like the China Meteorological Administration and international ensembles have reinforced trader focus on the 26°C outcome, though short-range model spread leaves room for 1°C shifts depending on exact timing of showers or clearer skies. No significant synoptic features, such as typhoon influences, appear imminent to alter the outlook.
