Strong model consensus from agencies including NOAA and ECMWF supports the market's near-certain 31°C outcome, as clear skies, moderate northeasterly flow, and typical early-September insolation over the North China Plain are expected to produce a daily maximum near that threshold. Recent surface observations from Zhengzhou stations show morning readings climbing steadily toward 30–31°C with dew points around 15°C and minimal cloud cover, aligning closely with climatological norms for the date. Minor forecast uncertainty stems from possible afternoon boundary-layer mixing or slight wind shifts that could cap the peak 1–2°C lower, though current guidance assigns low probability to deviations outside the 31°C bin.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 1 Sep '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=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 which 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 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.Strong model consensus from agencies including NOAA and ECMWF supports the market's near-certain 31°C outcome, as clear skies, moderate northeasterly flow, and typical early-September insolation over the North China Plain are expected to produce a daily maximum near that threshold.
