Trader consensus on 36–37°C for Shanghai’s August 1 maximum reflects current forecast guidance under the influence of the western Pacific subtropical high, which sustains hot, humid conditions across the Yangtze River Delta. Model consensus from agencies such as the China Meteorological Administration points to afternoon peaks near 36–37°C, moderated slightly by coastal breezes yet amplified by the urban heat island effect in the densely built city center. Differentiation between 36°C and 37°C hinges on minor variations in insolation, boundary-layer mixing, and any late-day convective cooling, with historical early-August climatology showing similar mid-30s maxima roughly 40–50% of the time. No major frontal systems or typhoon influences are indicated for the 24-hour window.
