Recent forecasts from multiple models indicate Zhengzhou will reach a daily high near 24–26°C on September 21 under mostly cloudy skies with light rain or drizzle, driven by persistent autumn rainfall patterns across Henan. These conditions, including high humidity near 80% and northerly winds, suppress daytime heating and align with late-September climatology where highs typically decline toward 24–26°C. Official guidance shows no strong warming trend or clearing that would support 27°C or above, while the lower tail below 25°C remains possible if rain persists longer. Trader consensus at 26°C (54%) and 25°C (29.5%) reflects this narrow forecast range and limited upside from current atmospheric steering.

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 21 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 forecasts from multiple models indicate Zhengzhou will reach a daily high near 24–26°C on September 21 under mostly cloudy skies with light rain or drizzle, driven by persistent autumn rainfall patterns across Henan.
