The Lowdown
Alright, Rusty here, and I’ve gotta be straight with you – the next couple of weeks are a tough watch for surf at Octagon House. We’re looking at a long, flat stretch with nothing worth paddling out for.
The problem? Tiny, weak swell – we’re talking wave energy barely cracking 7 to 34 (that’s weak to barely moderate) the whole 16 days. The swell is coming from the SSE or S, which isn’t the optimum SE direction this break wants. Periods are a short 4 to 5 seconds, so it’s all wind slop with no push. Winds are mostly onshore or cross-onshore from the SSE, just trashing what little bump there is.
The first real chance to even get interested, and it’s a long shot, is right at the very end: Monday, September 7th. Even then, we’ve got swell heights up to 3ft from the SSE with a 5-second period – that’s too short to form a proper wave. The wind is a moderate cross-onshore chopping it up, and the wave energy is still only 27 (weak). For a beginner spot like Octagon House, it's not offering a thing.
Honestly, there are long gaps here – this isn’t a spot that can manufacture a wave with this setup. For the whole 16-day window, there’s zero quality on offer. I’ve seen these blank runs before; it’s not unusual for this area to go quiet for a stretch. Keep an eye on the charts, but for now, save the petrol.
Rusty.
