Current forecast consensus from multiple models indicates a daily high near 28–29°C in Zhengzhou on September 22, driven by partly cloudy skies, light variable winds, and stable high pressure limiting daytime heating. This positions 29°C and 30°C as the market leaders, with differentiation hinging on subtle variations in cloud cover, boundary-layer moisture, and exact solar insolation under the influence of regional autumnal circulation patterns. Historical September averages around 25–26°C provide context, yet short-term model runs show modest warming from recent conditions. Official China Meteorological Administration observations will determine the precise maximum, with final model guidance expected before local sunrise. Trader sentiment reflects this tight range amid typical forecast uncertainty in maximum temperature 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.
