Weather models from China's Meteorological Administration and international ensembles point to a strengthening subtropical high over the Yangtze River basin, promoting clear skies, light winds, and intense solar heating that favor a peak temperature near 37°C in Wuhan on August 28. Late-August climatology shows typical maxima of 32–34°C, yet recent heat episodes and urban heat-island effects have routinely pushed readings 2–4°C higher. Ensemble spreads highlight modest uncertainty from possible late-day convection, keeping 36°C and 38°C as viable alternatives. Fresh model runs and observational updates over the next 48 hours will further shape trader assessments of these thresholds.

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.
