Recent cold front passage and associated rainfall through September 8 have introduced cooler, drier northerly air into Beijing, setting the stage for lower overnight minima on the 9th under mostly clear skies. Model consensus points to a daytime high near 25–28 °C followed by radiative cooling overnight, with the daily minimum likely occurring in the pre-dawn hours. Key variables separating the closely matched market outcomes (9 °C or below at 34.5 % versus 13–14 °C clusters near 25–27 %) include exact wind speed, residual moisture, and any late-model adjustments to boundary-layer mixing. Historical September 9 lows average 17.5 °C, so current guidance reflects a notable cool anomaly; traders will watch the next China Meteorological Administration forecast update and local station observations for resolution signals.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Beijing Capital International Airport Station in degrees Celsius on 9 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.Recent cold front passage and associated rainfall through September 8 have introduced cooler, drier northerly air into Beijing, setting the stage for lower overnight minima on the 9th under mostly clear skies.
