August: Plenty of Swell, But the Wind Rarely Lets Go
August is the height of the rainy season in southern Costa Rica, and the ocean reflects that. The average swell remains 3-4ft (1.1m) with a respectable 13.3s period, and SSW dominates again at 96.5%. The bulk of the surf is in the 3-5ft (1-1.5m) bracket (58.3%), with 34.6% in the 2-3ft (0.5-1m) range and 3.5% at 5-6ft (1.5-2m). But the ideal wind score plummets to 10%, among the lowest of the year, as W/WNW/WSW winds add texture to the lineup. Rainfall peaks at 8.85mm/day, air temperature sits at 25.5°C, and water temperature is 28.9°C. The afternoon onshore pulse is nearly a daily guarantee, so dawn patrol is your only real chance for clean, long-period Punta Banco waves in August.
