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 23 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Market-implied odds center on 18–19°C as the most likely maximum temperature for Cape Town on August 23, 2026, reflecting forecasts of clear to mostly sunny conditions under a strong South Atlantic High. This high-pressure system promotes subsidence and reduced cloud cover, allowing daytime heating, yet moderate southerly winds and persistent morning mist or low stratus—common in the Cape’s winter Mediterranean climate—limit rapid warming and cap the peak. A cold front that crossed the extreme south on Saturday introduced cooler air and stronger winds, setting up the stable post-frontal regime expected today. Official guidance from the South African Weather Service and numerical models consistently point to a daily maximum near 18°C, with limited model spread supporting the tight clustering around 18–19°C. Historical August averages for Cape Town hover around 17°C, so the current setup represents near-normal to slightly above-normal conditions given the high-pressure dominance. Traders assign the highest probabilities to these outcomes because any deviation would require unexpected changes in wind strength, earlier dissipation of coastal mist, or rapid warming from anomalous insolation—scenarios viewed as low-probability on the day of resolution. Upcoming observations from local stations and updated model runs through the afternoon will provide the final confirmation for market resolution.
