Recent cold fronts tracking south of the country have kept Cape Town cooler than seasonal norms, with South African Weather Service guidance and GFS/ECMWF model runs favoring a daytime maximum near 18–20 °C for August 21 amid moderate southerly winds and variable cloud cover. These conditions limit surface heating while the Benguela Current maintains marine-layer influence. Trader consensus clusters tightly around 21–23 °C because small shifts in front timing or wind speed could add 1–3 °C of warming, and updated model runs over the next 48 hours will likely resolve the narrow spread before resolution. Historical August highs average 17–18 °C, underscoring the sensitivity of the outcome to this week’s synoptic pattern.

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.
