Forecast models from agencies including the China Meteorological Administration indicate Chongqing's August 11 maximum will likely fall between 34°C and 37°C amid typical subtropical summer conditions of high humidity, light winds, and scattered afternoon convection. Recent runs show modest spread driven by variable cloud cover and thunderstorm timing, which can suppress peak readings by 1–2°C on any given day. Historical August climatology features mean highs near 34°C with occasional spikes above 37°C, but current guidance places the event near the upper end of average without extreme heatwave signals. Traders appear to weigh the narrow forecast envelope and resolution sensitivity to official station observations when assigning closely matched probabilities across the 35–37°C brackets. Updated model guidance over the next 48 hours will likely refine the exact peak.
