August: Late-Winter Groundswell and Westerly Gifts
August continues the winter run, with an average swell of 10ft (3.1m) and a 12.2s period. The south-west remains the dominant direction at 12.8%, followed by SSW (8.0%) and S (4.2%), while WSW adds another 1.7%. The E-ESE-SE-SSE window stays small at around 6 percent, but the consistency of solid, long-period groundswell keeps the waves on the beach almost every day.
Wind quality remains good. W (23.0%), WNW (6.2%), NW (3.7%) and NNW (5.9%) combine for roughly 39 percent of the time, and ideal surf wind is 31 percent. The E/ESE onshore flow starts to rebuild (E 6.0%, ENE 10.1%), but the winter westerlies still dominate the better part of the week. Air temp averages 15.0°C and water temp is 16.5°C, the coolest of the year. As the month progresses, keep an eye out for late winter swells that begin to swing more toward SSE/SE - those are the sessions that light up Seal Point.
