Conditions at Long Beach in August
August: Tropical Fuse Begins to Light
August marks the first real chance of tropical swell at Long Beach. The average wave height is still modest at 3ft (1.0m), but the average period lengthens to 7.6s, hinting at more organized energy. SE and SSE dominate again at 21.2% and 23.0%, with S at 19.7% and ESE at 12.6%. The presence of E/ESE swell and a few bigger classes - 3-5ft (1-1.5m) through 6-8ft (2-2.5m) - often correlates with tropical storms or hurricanes tracking up the western Atlantic. Those systems can send clean, longer-period swell into the south-facing Long Beach sandbars.
Winds are still mostly from the south: SSW 12.4%, S 11.9%, SW 10.4%, so afternoons are bumpy. But the ideal-wind percentage climbs to 29%, and mornings can be glassy as overnight NW/NNW breezes set up. Water temperature is at its warmest, 22.2°C, with air temps averaging 23.4°C and precipitation 3.58 mm/day. August is inconsistent, but the tropical potential alone makes it more interesting than June or July.
