Latest ensemble forecasts from the China Meteorological Administration, GFS, and ECMWF models indicate Beijing will see a daytime high in the mid-20s Celsius on May 18, following the passage of a weak northerly cold front that introduced cooler, cloudier conditions and limited solar heating. This setup keeps peak temperatures below seasonal climatological averages near 28°C while introducing uncertainty in exact maximum readings tied to variable wind speeds, residual moisture, and afternoon clearing. Market-implied odds cluster tightly around 25–27°C because small differences in model runs for frontal timing and boundary-layer mixing produce comparable probabilities for each threshold, with no strong signal yet for either a sharp rebound or further suppression.
