**Trader consensus has converged on 22°C as the day's maximum temperature in Cape Town due to consistent numerical weather model outputs and surface observations aligning on that peak under partly cloudy conditions with light southerly winds.** South African meteorological guidance and international ensembles such as those from the South African Weather Service indicate mild winter conditions typical for late August, with daytime highs supported by limited cloud cover and no significant cold-front influence until evening. Official station data from Cape Town International Airport and nearby sites have recorded afternoon readings approaching but not exceeding this threshold, reinforcing the market-implied outcome. A realistic challenge would require an unforecasted warm-air advection event or post-sunset measurement revision exceeding 22°C, though current model agreement and observational timing make such shifts improbable before resolution.

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 Cape Town International Airport Station in degrees Celsius on 21 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 Cape Town International Airport Station, available here: https://www.wunderground.com/history/daily/za/matroosfontein/FACT.
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.
