This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Guangzhou Baiyun International Airport Station in degrees Celsius on 7 Sep '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=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 official and model forecasts for Guangzhou on September 7 point to a daily high near 33–35°C under partly cloudy skies with scattered thunderstorm risk, aligning with market-implied odds favoring 34–35°C. Subtropical monsoon conditions, elevated humidity near 70%, and light variable winds support afternoon peaks in this range, while cloud cover and precipitation potential could cap readings below the historical September 7 record of 35.2°C. Recent days with highs of 30–32°C and rain have transitioned to drier patterns, allowing modest warming. Numerical weather models show limited spread, though late-day convection remains a key uncertainty that could shift the observed maximum by 1–2°C.
