The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
Right off the bat, I gotta be straight with you – this stretch is looking pretty flat. We’re talking about a long, quiet period with basically nothing rideable for the foreseeable future. The first proper bit of energy we see is tiny, and it’s all downhill from there for a while.
Looking at Octagon House (beginner spot, fairly consistent but exposed to the SE), the whole first week is a write-off. From Saturday the 29th of August right through to Friday the 4th of September, we’re seeing swell heights barely reaching 2 ft, with periods that are short and weak. The combined energy is a paltry 3 to 13 (weak energy). Winds are mostly onshore or cross-onshore, so the surface is going to be messy. The water temp is sitting at 87°, which is a touch warmer than normal for this time of year, but that’s about the only highlight.
The pattern doesn’t improve much into the second week. From Saturday the 5th of September through to Sunday the 13th, it’s the same story: tiny swell, mostly under 2 ft, with short periods. The combined energy does bump up a little, hitting 34 on the morning of Tuesday the 8th of September, but that’s still weak energy. Winds are still a problem – mostly onshore or cross-onshore, making for choppy conditions.
There is one glimmer. On Thursday the 10th of September, we get a morning of glassy conditions with a light NNW wind. The swell is still only 2 ft from the SSE, period a short 4 seconds, but with that glassy surface, it’s the cleanest the water will be all forecast. It’s still tiny, but for a beginner spot, that could be a little window for a fun, small-wave session. The combined energy is only 20, so don’t expect any power.
All in all, there’s no standout swell here. The best you can hope for is that tiny, clean morning on the 10th of September. For the rest of it, you’re better off finding another hobby until we get a proper pulse of energy.

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.
