**Trader sentiment for Cape Town's August 13 maximum temperature centers on a narrow 26–28°C band because short-range numerical weather prediction models show a warming trend from recent cool conditions, yet diverge on peak values due to variable synoptic influences.** Recent forecasts indicate a shift toward clearer skies and lighter winds by mid-week, allowing greater daytime solar heating in this Mediterranean winter regime, where average August highs hover near 17–18°C. Key differentiators include the strength and timing of any approaching cold front or high-pressure ridge, potential berg wind (foehn) effects that adiabatically warm descending air from the interior, and boundary-layer moisture from the cold Benguela Current, which typically caps extremes. Official resolution at Cape Town International Airport will hinge on these factors, with model ensembles reflecting the inherent uncertainty in 48-hour temperature maxima amid transitional winter patterns.

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.
