Conditions at Playa Dominical in August
August: Size and Humidity
August keeps the wet-season swell machine running hot. Average height is back up to 4.5ft (1.4m) with a 13.2s period, and the SSW/SW combo supplies virtually all the energy. Notably, over 26% of the waves reach 5-6.5ft (1.5-2m), and the 3-5ft (1-1.5m) range fills another 70%, making this one of the more powerful months of the year. The direction is beautifully aligned with Dominical's SSW-facing beach, so the long-period groundswell wraps in with real push.
As with June and July, the wind is the weak link. Ideal wind drops to 24%, one of the lowest of the year, and the SW/W/WNW flow that dominates the wind rose is mostly onshore or side-shore. Still, wind speeds remain light, and the window for clean surf opens up when the early-morning N/NNE land breeze kicks in. Expect heavy tropical rain (6.81mm/day), high humidity, air temps around 21.2°C (70°F), and water temps at 29.0°C (84°F). August is a groundswell banquet if you are willing to watch the weather like a hawk.
