The Lowdown
Alright folks, Rusty here. I’ll level with you straight up: this 16-day window for Octagon House is a real tough one to swallow. There isn’t a single session in the whole run that’s worth paddling out for. The swell is tiny, the period is short, and the wind is a problem most of the time. We’re looking at a long stretch of nothing, so don’t hold your breath.
The pattern starts with light, weak swell from the SSE. On Tuesday the 11th, we’ve got a meagre 2 ft on a 4-second period, all chopped up by a cross-onshore breeze. The combined energy is a pathetic 22 – that’s flat-out weak. Wednesday and Thursday don’t get any better, with the same tiny, short-period slop and moderate winds keeping it bumpy. There’s a brief moment of glass on Sunday morning the 16th, with a light westerly breeze making the surface clean, but it’s still only 2 ft of weak, short-period energy. You’d be bobbing around on a lake.
The next glimmer of hope comes on Friday the 21st with another glassy morning, but the swell is still only 2-3 ft from the south with a 5-second period. The energy is just 32. It’s clean, but there’s no push. The last few days of the window see the swell trying to push a little higher, hitting 4 ft on Sunday the 23rd, but that’s accompanied by a fresh cross-onshore breeze and a risk of thunderstorms. The period is still a short 6 seconds, so it’s just messy, blown-out slop.
In short, the whole 16 days is a write-off. The water temperature is about average for the time of year, so that’s no comfort. For a beach break setting like this, the setup is honestly more interesting for kite surfing than paddle surfing when the wind picks up. There’s just nothing to work with. Keep the board in the car and wait for the next change.

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.
