**Traders are pricing 38°C as the most likely peak for Chongqing on August 16, reflecting current numerical weather prediction guidance from Chinese meteorological sources showing daytime maxima of 38–39°C under partly cloudy skies.** Chongqing’s subtropical monsoon climate, combined with its basin topography and urban heat island effect, routinely produces mid-August highs of 34–38°C; recent model runs have held steady near the upper end of this range amid limited cloud cover and light southeasterly flow. Official forecasts from weather.com.cn list 38–39°C, while international guidance such as the UK Met Office is slightly cooler at 36°C, creating the observed market spread favoring 37–39°C. With resolution tied to the official daily maximum reported by the China Meteorological Administration, any last-minute changes in convective activity or insolation before the 16th could shift the outcome within the narrow 36–39°C band that now accounts for most probability.
