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 25 Jul '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.**Trader sentiment for Cape Town’s July 25 maximum temperature reflects tight clustering around 19–21 °C, driven by short-range model consensus for mostly fine, partly sunny conditions following an approaching cold front.** South African Weather Service guidance for 24–25 July indicates clearing skies and temperatures that are cool to locally warm, while several operational forecasts explicitly project an afternoon high near 20 °C under light winds and minimal cloud cover. Cape Town’s winter maxima are strongly modulated by the cold Benguela Current along the west coast, which caps daytime warming, and by the strength and direction of the southeasterly “Cape Doctor” winds that enhance mixing and limit thermal buildup. With the front expected to clear by the 25th, reduced cloud cover and subsidence should allow modest radiational warming; however, small differences in predicted wind speed, residual moisture, or the precise timing of high pressure building can shift the peak by 1–2 °C. Historical July averages hover near 17–18 °C, so the current market-implied range already incorporates a mild positive anomaly consistent with recent broader winter patterns. Model runs (GFS/ECMWF) and SAWS updates over the next 24–48 hours will be the key catalysts, as even minor revisions to cloud or wind fields can reallocate probability among the closely bunched 19–21 °C outcomes.
