August: Same Small-Swell Pattern, Slightly More Pulse
August mirrors July but with a faint pulse of renewed energy. Average swell height ticks up to 3.5ft (1.1m) and period sits at 8.5 seconds. W again dominates at 48%, with WNW at 20% and WSW at 13%, yet the majority of waves still fall in the 2-4ft (0.5-1.2m) range. There are a few more 5-6ft (1.5-2m) days than July, usually from distant North Atlantic storms or decaying tropical remnants that throw long-period energy toward Europe.
Ideal winds are 20%, and the battle between the offshore SW/WSW quadrant and onshore NW/NNW flow remains close. Water temperature peaks at 17.5°C - the warmest of the year - and air temps average 16.7°C. August is a fun, sociable surf month for summer boards, especially on the lower tides when sandbars show up and small west pulses wrap into the bay.
