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 6 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.
Forecast models from sources including NOAA-aligned data and regional meteorological services indicate Beijing's overnight low on September 6 will likely settle near 20–21°C under partly cloudy skies, light southerly winds, and moderate humidity around 50–70%. This positioning favors the 20°C outcome in trader consensus, as stable high pressure and limited cold-air advection maintain temperatures above the 18.2°C historical average low for the date. A modest cooling trend begins September 7 with incoming rain and northerly flow, but current observations and model runs show no sharp drop today. Uncertainty remains low given the late-summer pattern, though minor revisions in boundary-layer mixing could shift the exact minimum within the 19–21°C range.
