Recent cold fronts tracking across South Africa's western and southern coasts have lowered minimum temperatures in Cape Town below seasonal norms, with forecast models from sources like AccuWeather and local meteorological updates indicating overnight lows potentially dipping to 8–12°C amid clear skies and moderate south-easterly winds. This aligns with trader emphasis on outcomes at or below 5°C (leading at 43.5% implied probability) and clustered around 6–12°C, as August's climatological average minimum near 9–11°C can shift several degrees cooler under such synoptic patterns. Steep temperature gradients from the Benguela Current and reduced cloud cover overnight further support elevated odds for the lowest readings, with final resolution depending on official station data at Cape Town International.

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 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 lowest 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.
