Official observations from Beijing meteorological stations, including hourly data from Beijing Capital International Airport, confirm a peak temperature of 19°C around 3:00 PM local time on April 1, 2026, driving Polymarket's 100% implied probability on this outcome. Amid partly cloudy skies and light southerly winds, temperatures rose steadily from overnight lows near 9°C, exceeding initial forecasts from the China Meteorological Administration and Hong Kong Observatory (which projected a 17°C high) due to greater-than-expected solar insolation during spring warming. With solar heating past its peak and evening temperatures declining to the mid-teens, a realistic challenge would require a rare late-day revision in the official daily maximum from the China Meteorological Administration, though current data trends make this improbable. Final resolution data expected within hours.
