Recent meteorological observations and model consensus from agencies tracking Beijing's conditions point to a daily maximum of 25°C on September 24, aligning closely with the 1991–2020 climatological average high of 24.6°C amid typical late-September cooling. This market-implied outcome reflects trader assessment of verified station data and short-range forecasts showing stable temperatures without significant diurnal spikes or frontal influences. Official resolution hinges on precise maximum readings from authoritative networks, with minimal deviation expected given current atmospheric stability. Unlikely challenges include last-minute measurement revisions from instrumentation or localized microclimate effects, though historical records show rare excursions beyond 28°C on this date.
