**Forecast models and real-time observations point to clear skies and light northerly winds promoting radiational cooling overnight in Zhengzhou, driving the lowest temperature toward 19–20 °C.** Recent days show a cooling trend, with minima falling from the mid-20s earlier in the week to 20.5 °C on August 29 amid stable high pressure and minimal cloud cover. Official guidance consistently projects a low of 21–24 °C, yet trader consensus favors the lower end of that range given the potential for stronger nocturnal cooling under dry, calm conditions typical of late-summer high-pressure setups. Upcoming evening observations and any model revisions will refine resolution around these thresholds.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Zhengzhou Xinzheng International Airport Station in degrees Celsius on 31 Aug '26.
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 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.
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.**Forecast models and real-time observations point to clear skies and light northerly winds promoting radiational cooling overnight in Zhengzhou, driving the lowest temperature toward 19–20 °C.** Recent days show a cooling trend, with minima falling from the mid-20s earlier in the week to 20.5 °C on August 29 amid stable high pressure and minimal cloud cover.
