Current forecasts from multiple meteorological models and real-time observations indicate Zhengzhou will reach a daily high of 32–33°C on September 15, 2026, under mostly clear, southerly flow with minimal cloud cover and low precipitation chances. This aligns with late-summer atmospheric patterns in the North China Plain, where residual heat from prior weeks supports elevated maxima above seasonal averages of 26–28°C. Trader consensus at 100% for 32°C or higher reflects this strong model agreement and ongoing conditions as resolution approaches. Minor forecast revisions or localized cooling from an unpredicted frontal passage remain possible but would require substantial shifts inconsistent with current data.

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 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.
