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 18 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 model consensus from sources including AccuWeather and regional outlooks points to a daytime high of 34–35°C in Guangzhou on August 18 under typical subtropical monsoon conditions, with scattered thunderstorms and moderate rain expected to limit peak heating through increased cloud cover and evaporative cooling. High humidity near 80% and light easterly winds will further moderate surface temperatures while maintaining elevated heat indices. Historical mid-August climatology shows average highs near 33°C, and the current setup aligns closely with that baseline absent any strong high-pressure ridge. Traders appear to weigh the balance between brief clearing periods that could allow a 36°C spike and more persistent convective activity favoring 34°C, with resolution hinging on the next 48-hour forecast updates from official agencies.
