August: Late-Winter Swell With a Spring Smile
August is the tail end of the best season, and it still packs a punch. Average swell sits at 6ft (1.9m) with a 10.7s period. S (16.6%) and SSE (14.6%) remain the dominant swell directions, and the E sector starts to creep back in at 10.4%, a hint of the summer pattern to come. The 1.5-2m (5-6.6ft) and 2-2.5m (6.6-8.2ft) S bins are still well stocked, so quality groundswell waves are common. Winds are ideal 47% of the time, with NNW (12.6%), NW (12.2%) and WNW (12.4%) giving plenty of offshore opportunities; SW (11.0%) and SSW (8.9%) provide the usual frontal hiccups. Water temps bottom out at 13.5°C, air averages 9.6°C, and rainfall eases to 2.94mm/day. The surf is still excellent, but the weaker solar heating means lighter morning offshores - a great month for a hood and a step-up.
