Persistent rain, overcast skies, and northerly flow have kept Zhengzhou temperatures suppressed on September 9, 2026, with official forecasts and station data showing a daytime high near 18°C amid light to moderate precipitation and high humidity. This aligns with the market's 95% implied probability on 22°C or below, as the cool air mass and cloud cover have prevented typical September afternoon warming. Historical September highs average near 29°C, making the current anomaly notable. Updated model runs or earlier clearing of clouds could allow modest warming toward the upper end of the low-probability outcomes, though observations through midday reinforce the cooler trajectory.

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.
