**Forecast model consensus points to a September 1 high in Zhengzhou near 29–31 °C under sunny skies and moderate northeasterly flow.** Multiple sources project 29–31 °C, reflecting subtle differences in boundary-layer mixing, exact insolation, and low-level advection as summer monsoon influence wanes and autumn cooling begins. Clear conditions favor strong daytime heating, yet NE winds of 10–20 km/h limit extreme maxima compared with late-August peaks near 32–33 °C. Historical early-September averages hover around 28–30 °C, placing the market’s tight clustering at 30 °C (42 %) and 31 °C (36.5 %) in line with model spread and the narrow margin between those thresholds. Resolution will depend on official station observations once the day concludes.

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.**Forecast model consensus points to a September 1 high in Zhengzhou near 29–31 °C under sunny skies and moderate northeasterly flow.** Multiple sources project 29–31 °C, reflecting subtle differences in boundary-layer mixing, exact insolation, and low-level advection as summer monsoon influence wanes and autumn cooling begins.
