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 15 Jun '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 consensus at 100% for a 17°C maximum in Cape Town on June 15 reflects strong alignment between mid-winter climatology and current conditions. June averages hover near 17–18°C as the subtropical high-pressure system and cooler westerly flow suppress daytime peaks, with official South African Weather Service guidance and ensemble models showing no significant warm-air advection or berg wind events. This outcome matches historical June maxima and recent observations of 15–16°C under clear to partly cloudy skies. A realistic shift would require an unexpected strengthening of offshore flow or model error in boundary-layer mixing that pushes readings above 18°C, though such deviations remain statistically rare this time of year.
