Conditions at Sosua in August
August: Tropical Swell Season Begins
August remains small on average - 3.6ft (1.1m) at 7.4s - but the character of the Atlantic is changing. While E (56%) and ENE (39%) swell still dominate, the increasing number of tropical waves and early hurricane systems means the forecast models look alive more often than the averages suggest. Ideal wind windows are high at 47%, and ESE/SE trades are present but often light enough to leave the ocean flat and clean in the morning. Air temps peak at 27.8°C, water temp warms to 28.3°C, and precipitation climbs to 2.1mm/day. If a low-pressure system forms in the tropical Atlantic and tracks west or north of the island, this is one of the few summer months when a 4-6ft (1.2-1.8m) swell can appear. Otherwise, expect small, fun trade-wind waves.
