The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at the next couple of weeks, it’s a bit of a flat spell for the Octagon House area. The water is running a touch warmer than normal at 87°, which is nice for a paddle but doesn’t help the waves.
Right from the get-go on Sunday the 13th, we’ve got tiny, weak swell. We’re looking at ankle-snappers around 2 ft from the SSE, but the wind is on it or cross-onshore, and the energy reading is a measly 21 (weak). The whole first week is pretty grim – day after day of poor surf conditions. There’s a little bump Thursday the 17th, with swell jumping to 4 ft from the ESE and energy climbing to 113 (moderate), but it’s still cross-onshore at 16 mph, so it’ll be a choppy, messy mess. Not worth the drive.
We do see a brief window of clean conditions on Saturday the 19th morning. A light offshore WNW breeze at 6 mph will make the surface glassy, but the swell is only 2 ft with a weak energy reading of 30. It’s a tiny, clean wave for a beginner on a foamie, but nothing to get excited about.
Then it’s back to a long stretch of tiny surf and onshore junk. There are gaps of several days here with nothing to recommend. The swell stays below 3 ft for almost the entire second week, with short periods of 4 to 6 seconds. The energy rarely cracks double digits. It’s not until Wednesday the 23rd morning that we see another clean window with a light NNE cross-offshore breeze, but again, it’s just 2 ft of weak SE swell.
Honestly, there’s no standout session here. It’s a lean period. Keep the board in the car just in case, but don’t hold your breath. This is one of those times where the ocean just needs a few days to wake up.

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.
