Trader consensus on Polymarket has converged to a near-certain 100% implied probability for a 21°C high temperature at Beijing Capital International Airport on April 16, backed by real-time observational data from the China Meteorological Administration (CMA) and airport METAR reports showing a midday peak of 21°C under persistent light rain and overcast skies. Numerical weather prediction models, including short-range ECMWF and GFS ensembles updated within the last 24 hours, align on limited daytime heating due to cloud cover, northerly winds, and frontal passage, consistent with mid-April climatology where Beijing averages 18–22°C highs. As evening approaches with falling temperatures, further warming is improbable; realistic challenges would require an abrupt clearing and solar insolation spike before sunset, though current infrared satellite imagery indicates sustained cloudiness precluding this scenario. Final CMA daily summary expected post-midnight UTC.
