August: Solid SSW Swell with Fickle Winds
August is the last truly big month of the Southern Hemisphere swell season. Average height is back up to 1.4m (4.5ft) with a 13.2s period. The swell direction splits between SSW (83.5%) and SW (16.0%), and a solid 22% of waves push into the 1.5-2m (5-6.5ft) zone. The power is unmistakable, and the SW-facing beach is set up to handle it well.
However, the wind remains fickle. Ideal conditions hover at 23%, with the onshore flow and rain (7.86mm/day) making many sessions less than perfect. When the offshore NNE/NE/ENE mornings do align, expect clean, heavy, long-period walls. Water temperature is a steady 29.0°C, keeping the tropical vibe alive.
