Official hourly observations from Beijing weather stations, including data up to late afternoon, confirm the highest temperature peaked at 21°C (70°F) around 2:00 p.m. under mostly sunny skies with gusty winds up to 29 mph, driving trader consensus to 100% on this outcome as the market nears resolution. This exceeds initial China Meteorological Administration and ensemble model forecasts of 19°C, likely due to stronger-than-expected solar heating and low humidity (dropping to 7-10%). April climatology supports such highs near 20°C on clear days, with minimal cloud interference today. Final verification from Beijing Capital International Airport (ZBAA) records via Weather Underground could challenge this if a late-evening reading tops 22°C or if measurement revisions occur, though diurnal cooling patterns reduce that risk.
