The Lowdown
Alright folks, Rusty here. Let's be straight with you – this is a tough one to write. The whole 16-day window for Octagon House is looking pretty grim. I'm not gonna sugarcoat it.
We're looking at a long stretch of small, weak, and messy conditions. The first solid couple of weeks have next to nothing worth paddling out for. The swell is tiny, mostly coming in from the South and Southeast, with heights barely scraping 2 feet most days. The period is short too, mostly around 4 to 6 seconds, so you're getting wind chop, not real groundswell. The combined wave energy is weak, often sitting in the low double digits (23) or barely cracking 50 (50) on a rare afternoon. The wind is almost always a problem – constant cross-onshore, chopping everything up. There are a few clean windows on the Saturday 1st of August and Sunday 2nd of August mornings with cross-offshore winds, but the swell is just too weak to care about.
The only glimmer, and I mean a tiny glimmer, comes on Monday the 3rd of August. The morning shows a bit of a pulse with the swell hitting about 3 feet from the SSW, a period of 6 seconds, and clean conditions thanks to a cross-offshore breeze. The combined energy bumps up to a moderate 57. It's surfable, but it's ordinary. For a beginner, these tiny, clean conditions might be the most manageable, but it's still not great.
After that, it's back to the same old story – tiny, onshore slop all the way through to the 14th of August. There's a really weird spike on the 12th of August afternoon with a 10-second period from the SE and a combined energy of 52, but with a swell height of only 1 foot, it's just not going to do anything. This is a rare, extended period of poor conditions. For a spot that's "fairly consistent," this is a real bummer, but it happens. Forecasts can change.
Forget the big boards. Unless you're a dedicated beginner wanting to practice pop-ups in sloppy, knee-high mush, or a kite surfer looking for a strong cross-on breeze, there's nothing here. The water is sitting at a warm 87°, a touch warmer than usual for this time of year, but that's cold comfort.
Stick with it, something might turn up.
Rusty.
