**Official forecasts from the China Meteorological Administration and supporting numerical weather models indicate a daily maximum near 31°C in Beijing on September 23, 2026, under partly cloudy skies with light southerly flow and minimal precipitation.** This aligns with recent model consensus showing afternoon temperatures peaking in the low 30s Celsius, consistent with late-September climatology where Beijing’s average high is about 25°C but recent days have trended warmer. Real-time surface observations and satellite-derived data during daylight hours have reinforced this trajectory without significant deviations. While the market-implied 100% consensus on exactly 31°C reflects strong trader confidence in the forecast envelope, realistic challenges include localized cloud increases suppressing the peak by 1–2°C or a brief clearing episode allowing a slightly higher reading before official verification closes the period.
