Recent forecasts from multiple meteorological models indicate a highest temperature in Wuhan of 27°C on September 3, supported by persistent overcast skies, light rain, and northeasterly winds of 10–15 mph that limit daytime heating and evapotranspiration. These conditions align with early September climatology for the region, where average highs near 30°C are moderated by cloud cover reducing solar insolation. Trader consensus at 66% for 27°C reflects the tight clustering of official guidance around this threshold, with lower probabilities for 28°C or higher tied to any late-day clearing. Updated model runs and surface observations through midday will determine final resolution.

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.
