Market-implied odds reflect near-certainty that Cape Town’s maximum temperature on August 11 will reach 20°C, driven by South African Weather Service forecasts and model consensus projecting a daytime peak of exactly 20°C after morning cloud clears under moderate south-easterly winds. A recent cold front has established cool, stable conditions consistent with August climatology, where average highs hover near 18°C; the current setup favors a modest rebound to the forecast threshold without exceeding it. Realistic challenges include persistent low cloud or a shift in wind direction that caps readings below 20°C or allows brief warming above it before 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 11 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.
