Recent model consensus and updated forecasts for Beijing on September 21 highlight clear skies with southerly flow, supporting daily highs near 30–31°C through enhanced solar heating and reduced cloud cover compared to prior days. Official China Meteorological Administration guidance lists 29°C, yet several numerical models project 30–31°C amid low precipitation risk and moderate humidity levels around 40–50% that favor greater daytime warming. Traders have clustered on the 30–31°C outcomes because subtle differences in boundary-layer mixing and wind timing could shift the peak by 1°C, with resolution hinging on afternoon observations from the Beijing station. Historical September maxima near 28–30°C provide context, but current conditions favor the upper end of typical ranges absent unexpected frontal passage.

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.
