Recent forecasts from multiple models indicate a minimum temperature in Zhengzhou of 17–21°C on September 15, driven by clear to partly cloudy skies overnight with light southerly winds and dew points near 15–18°C. This range reflects typical early-autumn radiative cooling under stable high pressure, with limited cloud cover allowing temperatures to drop close to climatological September lows around 17°C. Model consensus supports the market's leading 17°C outcome at 55% implied probability, while slight discrepancies in boundary-layer moisture and wind forecasts sustain 45% odds on 15°C or below or exactly 16°C. Updated runs from agencies like the China Meteorological Administration will clarify any last adjustments before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 15 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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 a minimum temperature in Zhengzhou of 17–21°C on September 15, driven by clear to partly cloudy skies overnight with light southerly winds and dew points near 15–18°C.
