Current meteorological guidance for Chongqing on August 15 centers on a subtropical high-pressure ridge sustaining daytime maxima near 35–36 °C, consistent with the market’s leading 42.5 % implied probability for 36 °C. The city’s enclosed Sichuan Basin topography limits ventilation while urban heat-island effects and humidity above 70 % amplify observed peaks, though scattered afternoon convection may cap readings at 35 °C or allow brief excursions to 37 °C. Ensemble forecasts through mid-August show no frontal passages or monsoon surges that would shift the distribution outside the 34–37 °C band, aligning trader sentiment with historical August climatology and the narrow uncertainty range reflected in the 22.5 % and 21.5 % allocations to 37 °C and 35 °C.
