Conditions at Long Beach in August
August: Small and Seasonable
August follows July's lead with an average swell height of 3.9ft (1.2m) and periods of 11.3s, the lowest of the year. The dominant swell directions remain favorable - W (41.8%), WSW (29.9%), SW (14.1%) and WNW (9.8%) - so virtually all energy is aimed at the beach. The wind, though, is still the Achilles heel. WNW onshore flow rules at 33.2%, W adds 16.0%, and NW 9.8%, while offshore NE to ESE winds account for only 7% of the wind rose. Ideal surfing conditions tick up slightly to 18%, usually in the early mornings or during brief easterly outflow events. Water temp peaks at 14.2°C, air temp averages 14.9°C, and rain is scarce at 1.99mm/day. The south Pacific hurricane season is just starting to stir, and tropical remnants can occasionally add a pulse of long-period SW energy. Overall, August remains small and seasonable - not a month to ski, but workable with low expectations.
