**Official forecasts from the Henan Meteorological Bureau and supporting models indicate a daytime high of 28–29°C in Zhengzhou on August 27, 2026, driven by recent cold-air advection that has lowered temperatures 5°C below prior levels.** Overcast skies and northeasterly winds have limited solar heating while keeping conditions stable near this threshold. Multiple sources, including international models and real-time observations, converge on a peak around 29°C, aligning with the market’s near-certain consensus. Only substantial forecast revisions from the National Meteorological Center or unexpected clear-sky intensification could shift the outcome, though current data show low likelihood of such changes before resolution.

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 27 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.**Official forecasts from the Henan Meteorological Bureau and supporting models indicate a daytime high of 28–29°C in Zhengzhou on August 27, 2026, driven by recent cold-air advection that has lowered temperatures 5°C below prior levels.** Overcast skies and northeasterly winds have limited solar heating while keeping conditions stable near this threshold.
