Recent forecasts from multiple models indicate Beijing's overnight low on September 9 will likely settle near 15°C under clearing skies and light northerly winds following Tuesday's rain-cooled conditions. Radiative cooling under reduced cloud cover and drier air (dew points in the mid-teens Celsius) favors this range, with model consensus pointing to 14–16°C as the most probable outcomes. Historical averages for the date hover near 17.5°C, but the current pattern reflects a cooler post-frontal air mass. Traders weigh subtle differences in wind speed, humidity, and exact cloud timing that could shift the minimum by 1–2°C, keeping the top probabilities tightly clustered. Updated model runs overnight will refine the final range before resolution.

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.
