Current meteorological forecasts from regional models indicate a maximum temperature for Chongqing on May 18 most likely between 23°C and 26°C, driven by the Sichuan Basin’s topography that traps moisture and limits daytime heating under moderate subtropical high pressure. This setup produces scattered cloud cover and light southerly flow, keeping surface temperatures close to the mid-May climatological average of roughly 24–27°C while preventing stronger warming. Ensemble guidance shows minor disagreements over afternoon mixing and boundary-layer humidity, which explains why market-implied probabilities remain tightly clustered around 24°C and 25°C rather than shifting decisively higher or lower. Final thermometer readings at official stations tomorrow will resolve the market, with any last-minute changes in cloud thickness or wind speed capable of tipping the outcome by one degree.
