Recent forecasts from meteorological agencies point to a daily maximum of 31–32°C in Shanghai on August 25, driven by typical late-summer subtropical conditions with high humidity, light winds, and partial cloud cover limiting further heating. Persistent warm air masses and regional sea surface temperatures support these levels, consistent with August climatology where average highs reach 31°C. Trader positioning around these outcomes reflects model consensus and recent observations of stable heat without strong frontal systems or typhoon influences expected to alter the peak. Official measurements from the primary Shanghai station will determine resolution, with minor revisions possible from updated runs.
