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 8 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 from sources including the GFS and regional analyses show Beijing under northwest flow on September 8, 2026, with widespread cloud cover and 70-95% rain probability that will limit daytime solar heating. This setup favors a daily maximum near 21-23°C, a notable drop from the 28-30°C highs of the prior days, as cooler air advection combines with evaporative cooling from precipitation. Official observations will determine the exact peak, but the tight clustering of market-implied odds on 22°C and 23°C reflects broad agreement among ensemble runs on these thresholds while leaving room for modest shifts if rain timing or wind speed varies.
