Trader consensus on Polymarket has locked in a 100% implied probability for Beijing's highest temperature on March 25 reaching exactly 25°C, driven by confirmed observational data from the China Meteorological Administration's official weather stations. Hourly records and final daily summaries report a peak of 25°C amid mild spring conditions, with clear skies and light southerly winds preventing further warming beyond this threshold. This aligns with seasonal climatology for late March in Beijing, where average highs hover around 12–15°C but occasional warm fronts can push readings into the mid-20s, as seen in recent ECMWF model outputs prior to the date. Realistic challenges would require post hoc data revisions from quality control processes or disputes over measurement site standards—scenarios deemed negligible given the uniformity across multiple stations and no reported anomalies. No further updates expected as the market nears resolution.
