August: Warm Water, Small Swell, and Manageable Breeze
August remains in the low season, but it is arguably the most comfortable month of the summer at Point Dume. Average swell height is 0.9m (3ft) with a 12.3s period, and the swell direction is weighted heavily toward the optimal southwest quadrant: SW (33 percent), WSW (31 percent), SSW (18 percent), and a bit of S (2 percent) mixing in. Wave heights are modest, with 2-3ft (0.5-1m) dominating and the occasional 3-5ft (1-1.5m) set from the W. Wind is slightly better than June and July, with ideal conditions 58 percent of the time, and the typical afternoon WSW/W sea breeze develops a bit later, leaving more clean morning windows.
