Traders see the lowest temperature in Guangzhou on August 21, 2026, clustering around 26–27°C because official station data and model consensus point to limited overnight radiative cooling under persistent cloud cover and high humidity typical of the subtropical monsoon pattern. Recent forecasts from sources including AccuWeather and the UK Met Office indicate nighttime lows near 26–27°C, with some runs showing brief clearing that could allow a dip toward 24–25°C. Key differentiators include wind speed, urban heat retention, and any late-day showers that trap heat near the surface. Market-implied odds reflect this narrow uncertainty band, with traders weighing the final official minimum against historical August averages around 26°C.

This market will resolve based on the lowest 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 lowest temperature recorded at the Guangzhou Baiyun International Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
