Current ensemble forecasts from regional models place Cape Town’s August 21 maximum near 17–19 °C under mostly cloudy skies and moderate onshore flow, consistent with the seasonal average high of 18 °C at the airport station. Trader positioning favoring 21–23 °C (combined ~75 % implied probability) appears driven by uncertainty in frontal timing and boundary-layer mixing: a slightly delayed or weaker cold front could allow greater daytime heating, while reduced cloud cover would increase shortwave radiation. Key variables include 10 m wind direction, which modulates the marine layer, and any late-day clearing that could push the peak 1–2 °C above guidance. Updated SAWS and global model runs over the next 48 hours will narrow the range ahead of market 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.
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.Current ensemble forecasts from regional models place Cape Town’s August 21 maximum near 17–19 °C under mostly cloudy skies and moderate onshore flow, consistent with the seasonal average high of 18 °C at the airport station.
