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 4 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.
Recent forecasts from the China Meteorological Administration and international models converge on a September 4 high of 32–33°C in Beijing under mostly sunny skies and light winds. Stable high pressure, low humidity near 30–40% during peak heating hours, and minimal cloud cover support efficient solar warming, while typical early-September climatology shows averages near 26–28°C. Trader consensus clusters on these outcomes because small differences in model timing for peak insolation or boundary-layer mixing could shift the exact maximum by 1°C, with 34°C remaining possible only if afternoon clearing is stronger than currently projected. Updated runs ahead of the daily maximum will refine resolution criteria.
