Beijing's official meteorological stations, guided by China Meteorological Administration data and consistent with National Meteorological Center observations, recorded a daily maximum of 28°C on June 14 amid partly cloudy skies, moderate northeasterly winds, and humidity near 85% that limited further warming. This aligns with late-day measurements showing stabilization around that threshold after morning lows near 19–20°C, reflecting typical early-summer patterns where solar heating peaks but atmospheric mixing prevents exceedance. The market's 100% consensus on 28°C reflects this locked-in observational certainty late in the resolution window. Only an unprecedented revision from primary gauges or undisclosed station anomalies could alter it, both highly improbable given real-time verification protocols.
