August: Hurricane Season Hums in the Background
August remains in the low season but with a subtle upgrade. Average surf height is still only 0.8m (2.5ft), yet the average period lengthens to 7.2s as more tropical systems develop across the Atlantic. The swell window is even more favorable: E, ESE, SE and SSE directions combine for nearly 70% of the wave spectrum, with the SE/SSE sectors doing most of the heavy lifting.
Most days are still small and windswell-driven, but August is prime time for hurricane swell on the East Coast. A well-placed cyclone off the southeastern seaboard can deliver 3-5ft (0.9-1.5m) or better ESE/SE groundswell, often with clean conditions as the system pulls SW winds around it. Ideal wind percentages sit around 44%, with the standard afternoon sea breeze from the southwest. Water temp peaks at 23.4°C, making it the warmest month of the year. If you want small, playful summer surf with a chance of tropical magic, this is the month.
