**Persistent subtropical high pressure and post-sanfu heat continuation are anchoring trader expectations for a peak of 37–39°C in Wuhan on August 27.** Official Hubei meteorological forecasts and multiple international models (including WeatherBug, PredictWind, and Met Office guidance) project daytime highs of 36–38°C under mostly sunny to partly cloudy skies, with only low chances of scattered showers that are unlikely to suppress the maximum. Center-city readings are specifically flagged at 37–38°C, aligning closely with the market’s leading outcomes (38°C at 38.5%, 37°C at 26%, 39°C at 25%). Wuhan’s location in the Yangtze River valley amplifies temperatures through urban heat-island effects and elevated humidity, while light easterly or northerly winds limit mixing. This follows the fifth-hottest sanfu period on record (1961–2025 baseline), sustaining the warm anomaly into late August. Cooling is not expected until typhoon-related moisture arrives around August 30, keeping August 27 firmly in the current hot regime. Traders appear to price in modest forecast spread around the official station maximum, favoring the 37–39°C cluster while assigning low probability to extremes outside 36–40°C given model consensus and the short two-day lead time.

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 27 Aug '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 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.**Persistent subtropical high pressure and post-sanfu heat continuation are anchoring trader expectations for a peak of 37–39°C in Wuhan on August 27.** Official Hubei meteorological forecasts and multiple international models (including WeatherBug, PredictWind, and Met Office guidance) project daytime highs of 36–38°C under mostly sunny to partly cloudy skies, with only low chances of scattered showers that are unlikely to suppress the maximum.
