Conditions at Sealion Cove in August
August: Warmest Water, Shortest Periods
August remains firmly in the low season, but the ocean starts to stir just a little. Average heights tick up to 1.4m (4.6ft), yet the period drops to 9.8s - the shortest of the year. That means a lot of lumpy, short-period windswell from SW (30.2%) and WSW (30.5%), with W at 9.0%. There are still plenty of 1-1.5m wave heights in the mix, but the lack of period robs them of any real push.
Ideal offshore wind is at 34%, and the onshore WNW/NW component remains strong at nearly 23%. Water temperature peaks at 14.2°C, the warmest of the year, with air at 12.9°C and precipitation rising to 6.06mm/day. August is a month for the patient surfer who knows the cove can occasionally offer a clean summer waist-high session between sea-breeze bumps - but expectations should stay modest.
