Current forecasts from multiple models indicate Cape Town overnight lows on August 22 will likely settle between 9–13 °C, with 10–12 °C as the most probable range given partly cloudy skies, light variable winds, and moderating influence from the cool Benguela Current. Radiative cooling under limited cloud cover and weak northerly flow allows surface temperatures to drop further after sunset, while any increase in wind or thicker marine layer would limit the minimum. Historical August data show typical minima near 8–11 °C, with recent days recording 5–12 °C, supporting the tight clustering of market-implied probabilities around these central outcomes. New model runs or observed cloud trends tonight will be the key near-term drivers of shifts.

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 22 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.
