Trader consensus on Polymarket assigns a near-certain 100% implied probability to a 25°C high temperature in Beijing on April 27, driven by China Meteorological Administration (CMA) observations at Beijing Capital International Airport—the official resolution source—confirming a midday peak of exactly 25°C under hazy sunshine, light northerly winds (16-24 km/h), and a subsiding high-pressure ridge fostering efficient boundary-layer heating from overnight lows near 9°C. This aligns with updated ECMWF and GFS model runs, building on yesterday's 24°C actual high amid spring warming trends exceeding late-April climatological averages of 22°C. With the sun setting and temperatures declining, realistic challenges are minimal but could involve post-peak measurement revisions from CMA's final hourly bulletins or rare urban heat island effects pushing marginally higher, though low probability persists ahead of midnight UTC airport data lock.
