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 3 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 forecasts for Guangzhou on September 3 point to a high near 29–32°C amid thunderstorms and persistent cloud cover, aligning with the closely matched market odds around 30–31°C. Northwest winds, high humidity near 70–80%, and widespread overcast conditions limit solar heating and promote evaporative cooling, keeping daytime maxima below the 32.8°C September climatological average. Model consensus shows variability in shower timing and breaks in cloud cover that could allow brief warming to 32°C or cap it at 29°C, creating the tight probability spread. Updated numerical guidance and official observations tomorrow morning will clarify resolution thresholds.
