Recent forecasts from the Guangdong Meteorological Bureau and international models indicate overnight lows in Guangzhou on September 23 near 25–27°C, driven by weak cold air advection, widespread cloud cover, and thunderstorm activity that limits radiative cooling. Persistent rain and high humidity further moderate temperature drops, aligning with historical September patterns where average lows reach about 23.5°C but recent days have trended warmer. This setup creates tight market-implied odds between cooler outcomes below 22°C and warmer ones above 30°C, as small shifts in steering patterns or model consensus on convective timing could alter the exact minimum. Official CMA updates and final overnight readings will resolve the market.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Guangzhou Baiyun International Airport Station in degrees Celsius on 23 Sep '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=zggg
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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 forecasts from the Guangdong Meteorological Bureau and international models indicate overnight lows in Guangzhou on September 23 near 25–27°C, driven by weak cold air advection, widespread cloud cover, and thunderstorm activity that limits radiative cooling.
