Recent model consensus from agencies like the China Meteorological Administration points to widespread cloud cover and scattered showers across Chongqing on June 26, driven by strengthening East Asian monsoon flow and a passing mid-level trough, which limits daytime solar heating and caps maximum temperatures near 24–25°C. High relative humidity (often exceeding 80%) reduces the diurnal temperature range through enhanced latent heat release and evaporative cooling from precipitation, while light northerly winds prevent strong downslope warming from surrounding terrain. These conditions contrast with typical late-June climatology of 29–32°C under clearer subtropical high influence, creating tight clustering around lower outcomes as traders weigh forecast uncertainty in convective timing and intensity.
