Forecast models from multiple sources indicate a stable high-pressure system over Beijing on September 14, supporting clear skies and daytime heating that favor a maximum temperature near 26–28°C. Subtle differences between 27°C and 28°C outcomes hinge on projected peak insolation, boundary-layer mixing, and light southerly winds that could enhance or limit surface warming by a degree or two. Low precipitation probability and minimal cloud cover reduce uncertainty, while historical September climatology places typical highs in this range. Updated global model runs in the next 24–48 hours will likely refine the exact peak, with traders monitoring any shifts in steering patterns or thermal advection.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zbaa
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
