Traders assign the highest implied probability to a 34°C peak in Chongqing on August 5 because official forecasts from sources such as the China Meteorological Administration and BBC Weather converge on a daytime high near 33–34°C under partly cloudy to overcast conditions with light easterly winds. August climatology in this subtropical basin—surrounded by mountains that trap heat and moisture—typically produces average highs of 32–34°C, with humidity above 70% limiting nocturnal cooling but also moderating extreme daytime spikes absent strong subsidence. Recent model runs show no major heat advection or clear-sky intensification that would push readings to 35°C or above, while scattered showers and cloud cover keep the upper tail (36°C+) below 3% probability. Updated guidance expected later today could refine the exact maximum before resolution.
