Recent northerly winds and widespread precipitation across Henan province have driven cooler, overcast conditions in Zhengzhou, limiting daytime heating on September 9. Official observations and short-range model guidance indicate a maximum temperature near 18°C amid persistent cloud cover and showers, well below seasonal norms of 26–28°C. This data underpins the market-implied near-certainty of 22°C or below, as aggregated trader positions align with verified measurements rather than longer-term averages. A sudden clearing of skies before sunset remains the primary scenario that could push readings marginally higher, though current atmospheric stability and timing make such shifts improbable.

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 9 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 northerly winds and widespread precipitation across Henan province have driven cooler, overcast conditions in Zhengzhou, limiting daytime heating on September 9.
