The Lowdown

Alright folks, Rusty here. Let’s get straight into it. I’ve been staring at this run for Octagon House and, well, it’s a tough one. We’re looking at a pretty flat spell to kick things off, with a real stretch of small, weak, and messy conditions. The first half of the 16-day window is a write-off for any decent paddle session. There’s a gap of several days with nothing worth recommending.

Now, the only real flicker of hope comes right at the back end. On Monday, 21st September, we might get a little something. The morning is showing a bit of life with a 3 ft swell from the SSE, period around 8 seconds, and the combined energy is a moderate 74 – a noticeable step up from the rest of the run. The wind is a clean cross-offshore from the NNE at 13 mph, which is a key positive for this exposed spot. It should keep the surface glassy and tidy. The water temp is 87°F, a touch warmer than normal for this time of year, so you’ll be in the water in boardies.

This is a beginner-friendly spot, fairly consistent when it gets a pulse, but it can get crowded sometimes. For the size we’re talking about, it’s a perfect little wave for a learner or someone just wanting a fun, clean glide. The swell direction from the SSE is at least angled into the SE exposure of the break. It’s not a bomb, but it’s the only game in town. The afternoon on the 21st gets a bit more onshore and choppy, so the morning window is your only shot.

Honestly, for the rest of the 16 days, it’s a real struggle. The energy is mostly weak, the wind is often messy, and the wave heights barely get above knee-high. This is a tough forecast for Octagon House. If you’re desperate, keep an eye on that Monday morning, 21st September. Otherwise, it might be time to check the kite gear, because the wind is stronger than the surf most days.

Rusty.

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.
