Recent observations and official forecasts from Chinese meteorological services show Zhengzhou's overnight low stabilizing near 24°C amid cooling northerly flow and widespread cloud cover, with hourly readings and model consensus confirming this threshold rather than a deeper drop to 22–23°C. The market-implied 100% probability on 24°C reflects trader alignment with real-time surface data and regional guidance projecting minimal further cooling before sunrise on August 28. This positioning draws from established climatological patterns for late-August transitions in the North China Plain, where cold-air advection typically yields lows in the low-to-mid 20s°C. A modest revision in final verified minimums from the local station or an unforecasted clear-sky radiative cooling episode could still alter the recorded value.

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 27 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 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 observations and official forecasts from Chinese meteorological services show Zhengzhou's overnight low stabilizing near 24°C amid cooling northerly flow and widespread cloud cover, with hourly readings and model consensus confirming this threshold rather than a deeper drop to 22–23°C.
