Recent forecasts from multiple models indicate cloudy skies and widespread rain across Zhengzhou on September 20, limiting daytime solar heating and capping maximum temperatures near 23–25°C. This aligns with the market's heaviest implied probability on 22°C or below, as persistent cloud cover and northerly flow suppress the usual September highs. Historical September averages hover around 25–26°C, but the current pattern—marked by elevated humidity, light winds, and precipitation—favors the cooler side of the distribution. Updated model runs and official monitoring over the next 24 hours will refine exact peak values ahead of market resolution.

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.
