Current numerical weather prediction ensembles place Wuhan's September 1 maximum temperature most likely between 28–30 °C, reflecting the market's clustered probabilities around those thresholds. Subtropical high pressure, regional humidity from the Yangtze basin, and variable cloud cover are the dominant controls on daytime highs, with model spreads arising mainly from differences in simulated boundary-layer moisture and weak steering winds. Historical September means for the city fall near 29 °C, supplying a climatological anchor, while the latest China Meteorological Administration and global model runs continue to show modest day-to-day adjustments. Updated forecasts issued in the final 48 hours before the period will determine whether the distribution narrows or shifts.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Wuhan Tianhe International Airport Station in degrees Celsius on 1 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=zhhh
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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Current numerical weather prediction ensembles place Wuhan's September 1 maximum temperature most likely between 28–30 °C, reflecting the market's clustered probabilities around those thresholds.
