Recent post-frontal warming following a cold front's passage has driven South African Weather Service and ensemble model consensus toward a daytime maximum of 28°C in Cape Town on August 13, 2026, under mostly clear skies and light-to-moderate northerly winds that enhance boundary-layer mixing and insolation. This aligns with observed recovery from cooler conditions earlier in the week and matches the narrow range of official guidance, explaining the market's near-certain consensus on that precise threshold. Minor shifts in wind timing, cloud cover, or localized measurement at the primary station could still produce a 1°C deviation, though current data strongly constrain such outcomes.

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 13 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.
