June: Heavy Winter Swell and a Fight With the Wind
June is peak Southern Ocean season in energy terms. The average swell height reaches its annual maximum at 6ft (1.8m), the period stays strong at 9.4s, and W/SW-directed swell now makes up around 14.3 percent of the mix. S and SSE swells remain prominent with 16.2 and 15.6 percent respectively, so there is no shortage of power. The problem is wind. The ideal-wind score collapses to 16 percent, and the onshore SW-W quadrant accounts for a massive 44 percent of the wind rose, with W alone blowing 15.9 percent of the time. This is a raw, heavy winter month: expect stormy conditions, occasional 8ft (2.5m) plus swells, and a real sense of untamed energy. The rare clean day after a front passes is worth the wait.
