The Lowdown
Alright, folks, let's get real here. Over the next couple of weeks, from August 12th to the 27th, Octagon House is doing a whole lot of nothing. It’s a flat, weak stretch and there’s no way around it. You’re better off finding a different hobby for a while.
The first few days through the 15th are just plain bad. We’re talking 2ft to 3ft of lumpy, short-period slop, with the energy meter barely moving between 21 and 48. The wind is mostly onshore from the southeast, chopping everything into a mess. It’s poor surf, no two ways about it.
Now, Sunday morning the 16th gives us a little glimmer. The wind dies off to nothing, going glassy, and the 2ft of swell from the SSE will at least be clean on the surface. But it’s still tiny and weak, with only 28 units of energy. It’s a good morning for a longboard if you’re just looking to get wet, but that’s about it.
After that, it just flat-lines. The swell drops to under 2ft, often way under, and the energy gets real scarce, dropping to single digits by the 26th and 27th. A couple of mornings have clean conditions, like the 22nd with a dead calm, but there’s simply no swell behind them. It’s flat, plain and simple.
So, my honest take is this: there’s nothing worth getting out of bed for. This is a total blank. Keep your boards in the garage and maybe check back later. Forecasts can change, but based on this, the surf is going to be a no-show.

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.
