Latest ensemble forecasts from global and regional models, including the UK Met Office and WMO guidance, point to a 37–39°C daily maximum in Wuhan on August 27 under subtropical monsoon conditions with clear to partly cloudy skies, light easterly winds, and high humidity that limits nocturnal cooling while supporting strong daytime insolation. These align with late-August climatology of 33–38°C peaks and recent observations near 35–36°C. Tight market clustering around 37–39°C reflects genuine uncertainty in boundary-layer details such as exact cloud timing and advection strength, with new model runs and official China Meteorological Administration updates expected within 24–48 hours to refine the outcome before 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
