August: The Midwinter Grind
August remains in the grip of the winter pattern. The average swell is still a meaty 6.2ft (1.9m), with a 13.8s period, and 89% of the energy comes from the SSW; 24% of the swell is in the 6.5-8ft (2-2.5m) range and 53% in the 5-6.5ft (1.5-2m) range. There is no shortage of heavy water. What is in short supply is clean wind. Ideal surfing wind is just 21%, the lowest of the year, as S winds blow 45% of the time and SSW 36%, with a big chunk at 20-30kph. These strong S/SSW trades keep the ocean textured and often turn otherwise epic groundswell into a bumpy free-for-all. Water temperature bottoms out at 19.4°C, air at 20.8°C, and precipitation is almost non-existent at 0.02 mm/day. Keep your expectations flexible and your wetsuit warm.
