Forecast models from sources including GFS and regional agencies indicate a high near 28–30°C for Beijing on September 18 under partly cloudy to overcast skies with light easterly winds and modest humidity. Seasonal late-summer patterns feature weakening high pressure allowing gradual moderation from recent warmer days, while scattered moisture could trigger brief afternoon showers that limit peak heating by 1–2°C. This produces the tight market clustering around 28–30°C, as small shifts in cloud timing or boundary-layer mixing determine whether the daily maximum registers at the lower or upper end of that range. Updated model runs through September 17 will refine the exact threshold.

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 18 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 GFS and regional agencies indicate a high near 28–30°C for Beijing on September 18 under partly cloudy to overcast skies with light easterly winds and modest humidity.
