Trader consensus clusters around 35–37°C for Chongqing’s August 15 maximum because current numerical weather models indicate a subtropical high-pressure ridge will sustain daytime peaks near 36°C amid the city’s river-basin topography and urban heat-island amplification. High humidity above 70 percent and limited afternoon convection introduce the observed spread, with slight model differences in peak-hour timing or cloud timing able to shift the official station reading by 1–2°C. China Meteorological Administration guidance and ensemble updates through the next 48 hours remain the key variables that could move implied probabilities before resolution.
