August: Big Swell, Fading Wind Windows
August is a transition toward spring. Average swell height actually climbs to 4.6ft (1.4m), with ENE (20.2%) and E (18.7%) becoming more dominant again, while S still contributes 12.7%. Period sits at a solid 9.2s, and there is plenty of size in the 1.5-2m range, especially from ENE (3.3%), E (3.4%), ESE (2.7%), SE (3.2%), SSE (3.3%) and S (5.8%). The ocean is full.
The problem is wind. Ideal offshore flow drops to 28%, while N (19.2%) and NNE (20.4%) pick up strength and frequency, adding chop to otherwise good surf. Still, SSW (17.0%) and SW (9.1%) remain in the mix, and with 17.6°C water and 15.9°C air, a good 4-7ft (1.2-2.1m) day is very possible after a cold front clears. Rain is minimal at 2.96 mm/day.
