The Lowdown
Alright folks, Rusty here. Let’s have a look at the charts for the next couple of weeks.
Honestly, I’ve gotta be straight with you – it’s a tough run ahead. There’s a whole lot of nothing happening. The swell is tiny, the period is short, and most of the time the wind is just messing things up. We’re looking at a solid 16-day stretch with no good surf on offer at all. It’s a rare blank run for the area, but it happens. The forecast is pretty locked in for this kind of quiet, so don’t hold your breath.
The only spot in the game is Octagon House, a beginner-friendly break that’s fairly consistent but exposed to the south-east. The water temp is sitting at 87°F, which is a touch warmer than normal for this time of year. The swell is a sad little 1ft to 2ft from the south or south-southeast, with a period of only 4 to 5 seconds – that’s pure windswell, no energy behind it. The combined energy of all swells directed here is weak, barely cracking into the double digits (9 to 32). Nothing to get excited about.
For the first week, from Saturday the 22nd of August right through to the end of the month, it’s all poor surf conditions. Mostly cross-onshore winds from the south doing the damage, with a few mornings offering a light cross-off or cross-shore breeze, but the swell is just too small and weak to make anything of it. The waves are tiny, choppy, and lack any real push.
The second week, from the 1st of September onwards, is more of the same. The swell stays small, the period stays short, and the wind stays on it. A couple of mornings on the 2nd and 6th of September have a light breeze with clean conditions, but again, with only 2ft to 2ft of short-period swell, it’s a flat, glassy lake. Not a single stand-out day in the lot.
There is simply no good surf to chase in this 16-day window. The whole setup is more interesting for a kite surfer than a paddle surfer if the wind picks up, but for a wave, you’re better off staying home.
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.
