The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Octagon House. I gotta level with you straight up – it’s pretty grim out there, and we’re looking at a long stretch of very small, weak, and messy conditions. There’s not a single standout surf window in the whole 16-day forecast. The swell energy is just pitiful, staying in the low double and single digits for most of the period. We’re talking combined energy readings barely hitting 27 (units) on the better afternoons, but mostly stuck below 20. That’s just no good for a paddler.
We start off the forecast on Wednesday the 2nd of September, and honestly, it’s a write-off from the get-go. We’ve got a tiny 3ft swell out of the SSW with a short, weak period of 4 seconds, and a cross-onshore wind at 12 mph. It’s choppy and ugly. This limp pattern just drags on for days. We’re looking at a flat, blown-out run right through the first week and into the second. The water temperature is about average for this time of year, so no surprises there.
We get a little tease of glass on Sunday the 6th of September with a tiny 0.7ft swell and light winds, but it’s basically a lake. Then a bit of a clean-up on the morning of Monday the 7th with a light cross-offshore breeze from the WSW, but again, the swell is only 1.0ft. That’s not surfable. The energy stays weak and the period never gets beyond 6 seconds – it’s all windswell, no substance.
As we push into the second week, starting around Friday the 11th of September, the swell bumps up to 2ft, and the energy starts to climb into the 30s and 40s (units). By the weekend of the 12th and 13th, we see the biggest waves of the forecast at 3ft to 4ft from the SSE with a period of 6 seconds. The combined energy hits 83 (units) on the morning of the 13th, which is the most we’ll see, but it’s still moderate at best and the wind is cross-onshore. It’s gonna be choppy and won’t hold much shape.
Look, this break is exposed to the SE and the optimum wind is offshore from the NW, which we get a whisper of on the morning of the 16th of September. On that Wednesday the 16th, we have a cross-offshore breeze from the NNW at just 3 mph and a 2ft swell from the SE with a 6-second period. It’ll be clean, but the swell is tiny. Then on the final morning, Thursday the 17th, we get a light cross-offshore from the north with 2ft of SSE swell. Still too small to get excited about.
Honestly, for a beginner-friendly spot that’s fairly consistent, this is a rough run. But around here, with this kind of setup, a blank spell like this is pretty normal. There’s just nothing doing. Maybe check back in a few days, but for now, it’s a full two weeks of no surf for Octagon House.
Rusty.

Information about the Octagon House Surf forecast
The above surf forecast table for Octagon House provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Octagon House can be found by selecting the local surf guide option on the grey menu. Our Octagon House surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Octagon House) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
