The Lowdown
Right then, let's have a look at what's on offer for the next couple of weeks. I gotta be straight with you – this is a tough one. The outlook for the Octagon House area is pretty bleak for the entire 16-day window. We're looking at a long stretch of nothing special, with no real standouts to get excited about.
The water temp is a touch warmer than normal for this time of year, sitting at 87°F when it first registers, but that's about the only thing that's out of the ordinary.
For the whole period, we're dealing with tiny, weak swell. The combined energy of all swells directed here is barely registering, with values mostly in the teens and twenties – that's weak wave energy, plain and simple. Swell heights are hovering around 1ft to 3ft, and the periods are short, mostly 4 to 6 seconds, so it's just wind chop, not proper groundswell. The wind is almost always cross or cross-on, usually from the south, and often blowing at 12-16 mph, which is going to keep things choppy and messy.
There's a single morning on the 22nd of August where we get a light cross-offshore breeze from the WSW at 6 mph, and the wave comment is "clean". That's the best we see, but even then the swell is a tiny 2ft from the south with a 4-second period. It's a flicker of hope, but not enough to justify a paddle out.
The only other morning that looks clean is the 3rd of September, with a light north wind at 3 mph, but again, the swell is only 2ft with a 5-second period from the SSE. It's a long way off, and the energy is still weak at 20.
Honestly, given the persistent poor conditions, small swell, and choppy onshore winds, this setup looks more interesting for a kite surfer than a paddle surfer for the entire 16 days.
