Current forecasts for Zhengzhou on September 23 point to an overnight low near 19–22°C, driven by mild southerly flow and increasing cloud cover that limits radiative cooling. Models show partly to mostly cloudy conditions with light winds and minimal precipitation early, keeping temperatures elevated compared to clearer autumn nights. Trader consensus splits between 25°C or higher and 15°C or below because small shifts in cloud timing or wind direction can alter the minimum by several degrees; official Chinese meteorological updates and ensemble model runs in the next 24 hours will refine the exact threshold. Historical September lows average near 17°C, providing context for the current mild setup.

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.
