The Lowdown
Alright, Rusty here again. Let’s break it down for you in feet and Fahrenheit.
Honestly, straight up, it’s a grim stretch. We’ve got a solid sixteen-day window ahead, and there’s barely a bump worth paddling for. The first recommendation from the data doesn’t kick off until Thursday, September 3rd, but don’t get your hopes up – it’s all labelled as poor surf conditions right through. There’s a long, flat gap with nothing worth chasing. The whole run is pretty dry.
The only break we’ve got to talk about is Octagon House. It’s a fairly consistent beginner spot, exposed to the swell, and the optimum direction is from the southeast, which lines up with what little we’re seeing. But the numbers don’t lie: the swell is tiny for the whole 16 days, mostly between 0.3 ft and 2 ft, with short periods under 8 seconds. That’s windswell, not groundswell, so it’s going to be weak, choppy, and lacking any real push. The combined energy barely cracks double digits – for example, on September 9th it peaks at just 20 (weak energy). That’s lifeless.
On the positive side, the water temperature is sitting at 87°F with a 3°F anomaly, so a touch warmer than normal for the time of year. That’s the only bright spot.
Wind does offer a few fleeting moments of glass. On the morning of Friday the 4th and Saturday the 5th, we get glassy conditions with a SSW breeze at just 3 mph, but with the swell maxing out at 1 ft, it’s still unrideable. There’s a morning on Tuesday the 8th with glassy conditions again and 1.0 ft swell, but again, nothing to work with.
Sunday morning the 13th sees a slight bump to 2 ft but with a moderate cross-onshore wind up to 12 mph, it’s choppy and messy. Honestly, if you’re looking for something to do, the setup here looks more interesting for a kite than a surfboard on those windy afternoons.
There are no standouts. Nothing even comes close to a recommendation. It’s a rare flat spell that just won’t let up. Still, this spot is fairly consistent by nature, so it tends not to stay this poor for long. Forecasts can always change.
Stay hopeful, but for now, leave the board in the car.

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.
