The Lowdown
Alright, Rusty here again, same outlook but in feet and miles for you. Let’s go through it.
The next two weeks are going to be dead flat for Octagon House. From now through the 8th of September, every day is showing poor surf conditions. No real standouts at all.
Starting Monday, the 24th of August, there’s a tiny 0.3ft swell from the southeast with a period of 9 seconds, and combined energy is only 7 (weak). Wind is cross-shore, making the surface a bit messy. Water temp is 87°, which is a touch warmer than normal for this time of year, but that doesn’t help when there’s nothing to surf.
All through the week, swell heights stay below about 2ft to 2ft, came from the south or southeast, with short periods of 4 to 5 seconds. Combined energy never gets above 26, so there’s no power. Winds are mostly cross or onshore, so it’s choppy.
There are a couple of glassy mornings – Saturday the 29th and Wednesday the 2nd of September – but the swell is still tiny, around 1ft to 2ft. Clean surface but not enough to surf.
The 28th of August morning and the 3rd of September morning have clean cross-off winds, but again, tiny, weak swell.
This setup looks more interesting for kiteboarding than paddle surfing, given the onshore winds on some days. For surfers, it’s a long, boring gap.
This kind of flat spell is normal here. Forecasts can change, but for now, don’t bother waxing up. Rusty out.

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.
