The Lowdown
Alright, let’s break it down. Over these 16 days, Octagon House is in a deep, wave-less hole. Don’t expect to get much of a paddle in.
The first week, from Friday the 14th through to the 21st of August, is all small, weak junk. The swell energy is barely registering the meter, with values between 14 and 63. Swell heights are around 0.5 to 0.8 feet, with a short period of 4 to 6 seconds. That’s just messy windswell. The wind is mostly onshore out of the SSE or S, so it’s going to be choppy and poor. The only clean moments are on Sunday the 16th and Monday the 17th mornings when the wind goes glassy, but with a swell under 2 feet and no energy, there’s just nothing to surf.
The second week, starting the 22nd of August, the swell drops even more. We’re stuck with 0.4 to 0.6 feet of weak, short-period slop. The combined energy drops into the teens and low twenties. Winds stay mostly unfavorable, though a few mornings offer a light breeze. Even then, the swell is so tiny it’s not worth the drive.
This is a full-on drought. No standouts, no hope for a good wave. Unless you’re into flat-water paddling, leave the board at home. Sometimes it just isn’t happening.

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.
