Forecast models and official guidance from China's Meteorological Administration point to a mostly cloudy day on September 20 with limited daytime heating, anchoring trader focus on a 26–28°C peak. Recent cooling from northerly flow and elevated cloud cover have suppressed temperatures relative to earlier seasonal norms, while light northeast-to-southwest winds and minimal precipitation risk reduce upside potential. Ensemble spreads and hourly guidance show modest variability tied to exact cloud breaks and boundary-layer mixing, keeping probabilities distributed across 26–29°C rather than converging on a single value. Final resolution will hinge on verified maximum readings from Beijing stations, with updates expected through the evening of the 19th and morning observations on the 20th.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Beijing Capital International Airport Station in degrees Celsius on 20 Sep '26.
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.Forecast models and official guidance from China's Meteorological Administration point to a mostly cloudy day on September 20 with limited daytime heating, anchoring trader focus on a 26–28°C peak.
