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.
