Recent official forecasts from Chinese meteorological services and international models converge on a highest temperature of 31–32°C for Shanghai on August 28, driven by increasing cloud cover, scattered showers, and easterly winds that limit daytime heating relative to the clearer conditions of the prior week. Late-August subtropical monsoon patterns typically produce highs near 31–32°C with high humidity, and current runs show modest cooling from precipitation compared with recent 33°C peaks. Trader consensus reflected in the market prices aligns closely with these model outputs, while uncertainty remains around exact rainfall timing and any late adjustments in steering flow or local urban heat effects. Updated guidance from the China Meteorological Administration ahead of the date will provide the next key data points for resolution.
