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.
