**Traders have converged on a 25°C daily maximum for Zhengzhou on September 17, 2026, reflecting real-time model consensus and station observations showing highs of 24–26°C under mostly cloudy to overcast skies with light southerly winds and minimal precipitation.** Official guidance from sources such as the China Meteorological Administration and global ensembles indicates stable atmospheric conditions that suppressed daytime heating, keeping the peak near the seasonal September average of roughly 26°C while remaining below the warmer spell earlier in the month. With the trading day nearly complete, only a significant late-afternoon surge or official measurement revision would shift the outcome.

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.
