Recent cold air advection across Henan province has lowered maximum temperatures in Zhengzhou, with official forecasts from the Henan Meteorological Observatory and multiple numerical models indicating a peak of 26–28 °C on August 28 under mostly cloudy skies and persistent northeast winds of 2–4 m/s. Reduced insolation from cloud cover and modest boundary-layer mixing limit daytime heating relative to prior days, while dew points near 18–20 °C support the observed cooling trend. Model consensus clusters tightly in the mid-to-upper 20s °C, producing closely matched market-implied odds around 24–28 °C because small differences in timing of any clearing or wind shift could alter the daily maximum by 1–2 °C.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 28 Aug '26.
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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Recent cold air advection across Henan province has lowered maximum temperatures in Zhengzhou, with official forecasts from the Henan Meteorological Observatory and multiple numerical models indicating a peak of 26–28 °C on August 28 under mostly cloudy skies and persistent northeast winds of 2–4 m/s.
