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 8 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 updates from meteorological models position 33–35°C as the most likely range for Wuhan's highest temperature on September 8, 2026, aligning with market-implied probabilities led by 34°C at 40.5%. Clear to partly cloudy skies, light easterly winds, and stable high-pressure conditions are expected to support daytime heating without significant cloud cover or precipitation to moderate temperatures. Multiple guidance sources converge on afternoon peaks near 33–35°C, reflecting typical early-September patterns in the Yangtze River basin where seasonal warmth persists amid transitioning monsoon influences. Model spread introduces modest uncertainty around exact maxima, particularly from local urban effects or minor wind shifts, while official monitoring by Chinese meteorological agencies will provide the definitive observation for market resolution.
