The Lowdown
Alright, this is Rusty. Let’s talk about what’s happening at Octagon House.
Honestly, mate, if you’re looking to paddle out here over the next sixteen days, you’re gonna be waiting a long time. The whole run is a flat spell—nothing but tiny, weak waves and poor conditions. From September 9th right through to September 24th, every single session is rated as poor surf. The swell energy barely gets a pulse going, with combined energy figures hanging around mostly between 4 and 71, which is seriously weak stuff. There’s no stand-out swell to speak of, so you’re looking at ankle-biters at best.
The first few days, from Wednesday the 9th through Friday the 11th, it’s dire. We’ve got swell heights of just 0.3ft to 2ft, with short-period windswell around 4 seconds. The wind is cross-onshore or onshore, making it choppy and messy. Thursday the 10th morning sees a little bump to 1.0ft with a light cross-onshore, but it’s still nothing to get wet for.
We do see a slight uptick in size around Saturday the 12th and Sunday the 13th, pushing 2ft to 3ft, but the swell period stays short at 5 seconds, and the onshore winds ruin any chance of a clean wave. By Monday the 14th and Tuesday the 15th, it’s the same story: 3ft to 3ft of SSE swell, but still onshore, with combined energy only up to 66.
Now, the only real glimmer comes mid-week. Wednesday morning the 16th has a 2ft swell but it’s cross-onshore, so no dice. Friday morning the 18th and Saturday morning the 19th, we get a proper offshore wind (NNW and NW respectively) blowing clean. On the 18th, it’s 3ft from the SE at 6 seconds, combined energy 46. On the 19th morning, it’s 3ft from the SE at 6 seconds, energy 44. The wind is offshore, so the surface will be clean, but the swell is still tiny and weak. That’s the best of a bad bunch, but it’s not gonna get you barreled.
After the 20th, the swell just fades away again, dropping to 1ft by the 23rd. Even with some clean offshore wind on the 23rd morning and 24th morning, there’s no power.
Bottom line: this is a flat run for Octagon House. The water temp anomaly isn’t given, so no word on that. Crowds are sometimes a factor here, but honestly, you won’t be fighting for waves because there aren’t any. Wait for a better forecast.
