Trader consensus centers on an 18°C high for Cape Town on August 19 because short-range forecasts from the South African Weather Service indicate persistent cloud cover and light showers that limit daytime heating, keeping maxima near the August climatological average of 16–18°C. Atlantic Ocean moderation and the region's Mediterranean winter regime further constrain extremes, with model runs showing only modest variability from steering patterns or transient ridging. Recent cold-front passages have reinforced this range, while any clearing could briefly allow 19°C readings; probabilities for 20°C or higher remain low absent stronger subsidence or northerly flow. Updated model guidance over the next 48 hours will refine these implied odds ahead of 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 19 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.
