Official observations from Beijing Capital International Airport—the designated resolution source for this market—confirm today's highest temperature reached exactly 18°C, anchoring trader consensus at 100% implied probability for that outcome. This aligns with China Meteorological Administration guidance and ensemble forecast models like GFS and ECMWF, which projected peaks of 18–19°C amid persistent cloud cover, low-level moisture advection, and cooler northerly flows suppressing midday heating. April climatology typically sees Beijing highs near 20°C, but overcast conditions limited solar insolation today. Realistic challenges are minimal, limited to rare post hoc data revisions from official summaries, though initial hourly reports rarely shift final daily maxima.
