Forecast consensus from the China Meteorological Administration and global models points to a daily maximum of 31–32°C in Shanghai on August 23, 2026, under persistent subtropical high pressure and southeasterly flow. Scattered light rain and cloud cover are expected to suppress solar heating and cap peak temperatures near late-August climatological norms of 30–31°C, with dew points around 25–27°C maintaining high humidity. These conditions align with official guidance listing a maximum near 31°C, explaining the market's overwhelming preference for that outcome while assigning modest probability to 32°C. Minor model spread and the potential for brief clearing introduce limited upside risk, but no significant heat advection or dry spell is projected to push readings higher.
