This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Guangzhou Baiyun International Airport Station in degrees Celsius on 19 Aug '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Guangzhou Baiyun International Airport Station, available here: https://www.wunderground.com/history/daily/cn/guangzhou/ZGGG. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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 forecasts for Guangzhou highlight uncertainty in peak temperatures on August 19 amid subtropical monsoon conditions, with model runs showing highs potentially reaching 34–37°C depending on cloud cover, thunderstorm timing, and steering flows. High humidity and urban heat island effects in the Pearl River Delta amplify daytime warming, while scattered showers or stronger convective activity could cap readings near 34–35°C. Historical August averages near 33°C provide context, but recent model spreads and short-term variability in the East Asian monsoon keep 36°C and 37°C closely matched in trader consensus, reflecting the narrow margin between typical peak conditions and modest intensification. Updated National Meteorological Center guidance and next model cycles will likely refine these probabilities ahead of resolution.
