Recent short-range forecasts from multiple numerical weather prediction models, including GFS guidance, indicate mostly clear skies and light northeasterly winds over Zhengzhou on September 5, supporting maximum temperatures of 31–32 °C. These conditions stem from persistent high pressure and strong daytime insolation typical of early autumn in the North China Plain, where surface heating under minimal cloud cover drives afternoon peaks. Ensemble spread remains narrow, with limited model disagreement on timing of any thin cirrus or boundary-layer mixing that could shave 1 °C from the daily high. Historical September maxima in Zhengzhou average near 28 °C, making the current setup anomalously warm yet consistent with observed 2026 trends. Official China Meteorological Administration observations at 1400 local time will resolve the market.

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 5 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 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.Recent short-range forecasts from multiple numerical weather prediction models, including GFS guidance, indicate mostly clear skies and light northeasterly winds over Zhengzhou on September 5, supporting maximum temperatures of 31–32 °C.
