June: Winter Proper Brings Size and Clean Air
June is when the Southern Ocean really turns on. Average swell height reaches 1.9m (6.2ft) and the period stays in the powerful 11.9s range. The wind statistics are the best of the entire year: ideal offshore conditions arrive 28% of the time, led by a strong 16.6% share of NNW winds and big chunks of NW and WNW flow. The onshore SE/SSE/S contribution shrinks to roughly 16%, meaning the bay regularly sees the kind of offshore-groomed swell it was made for.
The swell mix favours SW at 29%, SSW at 22% and WSW at 10%, with a growing westerly influence that can make local winds and currents tricky but the open-ocean groundswell substantial. Expect punchy long-period surf, often in the 6-7ft (1.8-2.1m) range, with bigger sets under squally fronts. Water temperature falls to 16.1°C, air averages 13.8°C, and precipitation peaks at 2.66mm/day - proper winter conditions, well worth the rubber.
