The Lowdown
Alright crew, Rusty here again. Let's be real – the outlook for Octagon House is a bit of a bummer. We're looking at a long, drawn-out run of small, weak, and mostly messy surf.
The whole 16-day window is a tough one. The swell never gets going, topping out at a tiny 3ft at best, and that's later in the first week. The energy is laughable, with combined swell energy barely cracking 55 on the best day, and mostly sitting in the 20s and 30s. That's weak stuff. To make matters worse, the wind is stuck in that cross-onshore or onshore groove for the vast majority of the period, keeping things choppy and uninviting. For a beginner-friendly break, it's just not doing us any favours.
Let's run through the pain. From Monday August 10th through the end of the first week, we're looking at ankle to knee-high slop. The wind is a persistent problem – mostly SSE or S at 9 to 15 mph, blowing straight on or across the swell. It's a bunch of "poor surf conditions" days. The water temp is about average for the time of year, but that's small comfort.
There is a sliver of hope on Sunday August 16th morning. The wind goes glassy, dead calm, with a little 2ft southeast swell. It's tiny, but it'll be clean. That's the one morning you might get a fun little knee-high wave to yourself, if you're quick. But it's fleeting; the afternoon turns straight onshore again.
The second week is more of the same. We get a few more cracks at cleaner conditions on the 21st, 23rd, and 24th mornings with some light cross-offshore wind from the WSW, but the swell is still just 2ft to 2ft with a short period around 5 seconds. It's a flat spell that just won't quit. The 25th Tuesday morning is about as weak as it gets, with combined energy down to 10.
Honestly, there's nothing here that I'd call a standout. The only wave worth paddling for is that Sunday the 16th morning glass-off, but it's more of a "go for a paddle and a small wave" session than a surf. If you're desperate, that's your window. Otherwise, save your energy.
Rusty.
