Recent forecast guidance from multiple models points to a moderating influence from northerly flow and increasing cloud cover over Wuhan on September 21, keeping the daily maximum near 25–27 °C rather than the 30 °C readings seen earlier in the week. Higher humidity, a 40–70 % chance of showers or thunderstorms, and reduced solar insolation are expected to limit surface heating, with ensemble spreads centered on 25–26 °C. Traders appear to weigh the balance between partial clearing that could allow brief warming toward 27 °C and more persistent overcast or rain that would favor 24 °C or lower. The next official updates from the China Meteorological Administration and fresh ECMWF or GFS runs will likely refine these thresholds ahead of market resolution.

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 21 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.
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 forecast guidance from multiple models points to a moderating influence from northerly flow and increasing cloud cover over Wuhan on September 21, keeping the daily maximum near 25–27 °C rather than the 30 °C readings seen earlier in the week.
