The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the Octagon House area over the next couple of weeks. I gotta be straight with you right off the bat – this is a tough one. The whole 16-day window is a real struggle, with no good surf on offer at all. Every single day is marked as poor surf conditions, so we’re looking at a complete blank run from August 7th right through to August 22nd. That’s a solid two weeks of nothing to write home about.
The swell is tiny, absolutely tiny. We’re talking about a constant stream of weak, short-period windswell from the SSE and SE, with heights barely scraping 2 ft to 3 ft. The periods are stuck around 4 to 6 seconds, so there’s no real energy or shape to speak of. The combined energy of all swells here is weak, with values like 17, 14, and 10, just barely ticking over. The water temperature is about 86°F, which is about 2°F warmer than normal for this time of year, so the water’s warm, but that’s about the only positive.
And the wind? It’s a mess. For the first few days in early August, the wind is onshore or cross-onshore, and it just gets worse from there. By August 10th, we’re into moderate cross-onshore breezes and choppy conditions. It doesn’t let up. By August 22nd, we’ve got fresh cross-onshore winds at 19 mph making things lumpy. Even when the wind eases a little, like on August 15th, it’s still a light cross-onshore with wind ripples.
For a beginner spot like Octagon House, which is fairly consistent but exposed to the SE, this is a total washout. The swell direction is coming from the wrong side of the compass for it to work well, and the wind is just ruining any chance of a clean wave. With such small, weak, and choppy conditions, this setup actually looks more interesting for kite surfing than paddle surfing.
So, there you have it. A long, dry spell. This kind of blank run is more normal for the area when the trade winds lock in from the wrong direction, but it tends not to stay poor for long. Forecasts can change, so keep an eye on it, but for now, leave the board at home.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Octagon House may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
