Conditions at Cape Town in June
June: Heavy Southern Ocean Groundswell
June is the heart of Cape Town's winter. Average swell height climbs to 9-10ft (2.7-3.0m) with a 12.4s period, and the distribution tilts toward serious size: SW 19.2%, WSW 10.9%, SSW 8.3% and W 2.9%, plus an increased percentage above 2.5m (8ft+). This is powerful, heavy, expert-level surf. The cost is weather: NNW winds reach 25.4%, NW 8.8% and N 5.2%, so onshore frontal conditions are common. Yet the offshore quadrant remains active - SSE 11.1%, SE 11.9%, S 4.3% - and ideal windows hold at 36%, usually in the post-frontal clearing phase. Rain peaks at 2.77mm/day, air temp drops to 15.1°C and water temperature is 14.6°C. If you want to see Cape Town wild, this is the month.
