August: Big South Swells and a Southeast Trade Component
August is another prime month for south swell at Boca Damas. The average height remains 1.4m (4.6ft), with a 13.2s period, and the SSW/SW combo delivers 97.1% of all wave energy. Around 70% of waves are clean, rippable 3-5ft (1-1.5m), and a hefty 26% are 5-6.5ft (1.5-2m), with roughly 1% reaching 6.5-8ft (2-2.5m). The swell is powerful and consistent, thanks to the active South Pacific storm track. Wind is the usual wet-season story: ideal offshore flow occurs 20% of the time, while S/SSW/SW/WSW dominates at about 49%, almost always under 10kph. One difference in August is a stronger SE/SSE component in the wind rose, which can create a more cross-shore texture at the SSW-facing beach. Rain is heavy at 7.86 mm/day, water is 29.0°C and air 25.8°C. Early N/NNW offshore windows are worth chasing.
