August: Warmest Water and Hurricane Season Promises
August shows the first signs of autumn. Average swell edges up to 0.9m (3ft), and the period lengthens to 7.5s, the highest since the shoulder-spring months. SSE (25.7%) and SE (23.2%) remain dominant, with S (16.7%), ESE (13.3%) and E (9.4%) rounding out a summer-plus swell mix. Wind is still tricky: SSW (12.4%), S (11.9%), SW (10.4%) and WSW (7.4%) are common, but NNW (7.7%) and NW (5.1%) offer more morning offshore windows than mid-summer. Ideal conditions reach 30%. This is also prime Atlantic hurricane season, so long-period E/SE/SSE swells can arrive with only 20-30 hours' notice. Water temp is the warmest of the year at 22.5°C (72°F), with air near 23.4°C.
