Trader consensus strongly favors an 8°C low for Cape Town on August 23, 2026, driven by official forecasts and recent observations aligning closely with that threshold. South African Weather Service data and multiple models show overnight temperatures falling to approximately 8–11°C under clear to mostly clear skies with light southerly winds, consistent with typical late-winter radiative cooling in the region. Historical August minima near 9–10°C and the absence of incoming cold fronts or significant cloud cover support this narrow range. The 98% implied probability reflects high model agreement and current surface observations around 10–13°C midday trending downward. Only a substantial shift in steering flow or unforecasted fog could realistically push the low outside 7–9°C.

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 23 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.
