Forecast models from sources like AccuWeather and timeanddate converge on afternoon highs of 32–34°C in Zhengzhou on August 26 under persistent subtropical high pressure, typical for late summer in Henan province. This positioning drives the 50% market-implied probability on 32°C or higher, with substantial support for 29–31°C brackets reflecting minor uncertainties in cloud cover, humidity levels near 70–80%, and localized wind patterns that could moderate peak readings by 1–2°C. Recent observations show no significant frontal systems or monsoon influences arriving in the next 24–48 hours, consistent with historical August averages of 31–33°C. Traders monitor updated numerical weather prediction runs for any late shifts 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=zhcc
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.
