Recent forecast models from regional meteorological centers indicate a daily maximum temperature in Chongqing on May 18 most likely between 25°C and 27°C, driven by light southerly flow and variable low-level moisture that moderates afternoon heating under partly cloudy conditions. Ensemble guidance shows modest spread from boundary-layer mixing and timing of any light rain, keeping outcomes clustered around the mid-May climatological average of 26–27°C. These small differences in cloud cover and humidity profiles explain why trader-implied probabilities remain closely matched across 25–27°C bins, with limited upside potential for 28°C or higher absent stronger subsidence and clearer skies. Updated model runs expected within the next 24 hours will further refine the precise peak.
