The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for Octagon House.
Honestly, this is a tough stretch to call. The whole 16-day window is pretty flat and messy. There’s a heap of days with tiny, weak swell and onshore winds, so the surf is going to be poor for the most part. The first real glimmer of anything rideable doesn’t show up until the very end of the run.
We’ve got a long, dry spell from the start. Tuesday the 1st through to the 16th is mostly a write-off. The swell stays tiny – under 3.3 ft – and the wind is almost always cross-onshore or onshore, keeping the surface choppy and messy. The combined energy is weak, mostly under 100 (e.g. 12 to 141), which tells you there’s just no punch.
The only standout in the whole period, and I mean the only one, is the very last session. On Wednesday morning, 16th September, things finally line up. Octagon House is a beginner-friendly spot, fairly consistent, and exposed to the southeast. The swell is a tiny 3.3 ft from the SSE with a period of 6 seconds. That’s not much, but the magic is the wind. We get glassy, offshore conditions from the northwest (3.1 mph), which is a huge positive. The combined energy is moderate at 63, and the water temperature is about average for the time of year. It’s only a 1/10 call, but for a spot that’s been flat for weeks, that clean, glassy morning will be the best shot you’ll get. It’s a long wait, but if you’re desperate, that’s the one.
The rest? Don’t bother. The wind is messy, the swell is tiny, and it’s mostly poor surf conditions. It’s a blank run, and for this area, that’s just how it goes sometimes.
