The Lowdown
Alright, I’ve taken a look at what’s on the cards for Octagon House, and I’ve got to level with you – it’s a rough stretch. The whole 16-day window is pretty much one long flat patch with nothing that’s going to get a surfer excited. We’re talking tiny waves and average wind conditions for the most part.
From Thursday the 20th of August all the way through to Friday the 4th of September, there’s not a single session that rates well. The swell is tiny – we’re looking at 1ft to 2ft from the south and southwest, with periods hanging around a short 4 to 6 seconds. That’s just windswell bump, no real power behind it. The combined swell energy is weak, sitting at numbers like 11, 15, or 22 – nothing with any punch.
The winds are mostly cross-onshore or onshore from the south, which leaves the water choppy and messy. There are a couple of moments where the wind goes light and clean, like the morning of Saturday the 22nd of August, with a light cross-offshore breeze from the west-southwest, and again on Wednesday the 2nd of September morning with a light westerly. But even then, the swell is just too small – 2ft at best – to make anything of it. The energy is barely there.
Octagon House is an exposed spot that likes swell from the southeast, and we just aren’t getting that direction or any size. For a beginner spot that’s fairly consistent, this is a real dry spell. It’s the kind of stretch where you’d be better off doing something else, because the ocean isn’t giving us anything. The forecast can always change, but right now, it’s a blank run.
