The Lowdown
Alright, let’s break it down. Over these 16 days, Octagon House is in a deep, wave-less hole. Don’t expect to get much of a paddle in.
The first week, from Friday the 14th through to the 21st of August, is all small, weak junk. The swell energy is barely registering the meter, with values between 14 and 63. Swell heights are around 0.5 to 0.8 feet, with a short period of 4 to 6 seconds. That’s just messy windswell. The wind is mostly onshore out of the SSE or S, so it’s going to be choppy and poor. The only clean moments are on Sunday the 16th and Monday the 17th mornings when the wind goes glassy, but with a swell under 2 feet and no energy, there’s just nothing to surf.
The second week, starting the 22nd of August, the swell drops even more. We’re stuck with 0.4 to 0.6 feet of weak, short-period slop. The combined energy drops into the teens and low twenties. Winds stay mostly unfavorable, though a few mornings offer a light breeze. Even then, the swell is so tiny it’s not worth the drive.
This is a full-on drought. No standouts, no hope for a good wave. Unless you’re into flat-water paddling, leave the board at home. Sometimes it just isn’t happening.
