Persistent warm air and elevated humidity across Henan province kept overnight lows elevated in Zhengzhou on August 26, with official observations from the Xinzheng International Airport station recording a minimum of 25°C or higher under mostly cloudy conditions. Subtropical monsoon influences and the absence of a significant cold front or heavy precipitation prevented typical radiative cooling, aligning with historical late-August patterns where nighttime temperatures frequently remain above 24°C. Trader consensus at 100% for 25°C or higher reflects this verified data from national meteorological networks. Only an unexpected localized measurement revision or station-specific anomaly would realistically alter resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
