The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the Octagon House area.
So, straight up, we've got a pretty grim run ahead. The whole 16-day window is looking flat, with barely a ripple to get excited about. The swell is tiny, the period is short, and the wind is mostly cross or onshore. It's a real bummer.
We start on Sunday, August 23rd, with a tiny 1ft SSE swell, but it's got a short period of 4 seconds and the wind is cross. The combined energy is a measly 5 (weak), and the conditions are described as poor. That's the story for the next few days. Monday, Tuesday, Wednesday… all the same. Tiny, weak swells, poor surf. The water temperature is sitting at 87°, which is a touch warmer than normal for this time of year, but that’s about the only thing that’s not a letdown.
The entire first week, right through to the end of August, is dominated by tiny swells under 2ft, all from the SSE or S, with periods of 4 to 5 seconds. The wind is almost always a cross or cross-onshore breeze, making for choppy, unappealing conditions. The combined energy never gets above 25 (weak). There is just nothing to recommend here.
We get a little flash of something on Friday, September 4th, in the morning. A tiny 1ft SE swell, but the wind goes light and cross-offshore from the NNE, and the water goes clean. The energy is still only 10 (weak), so it's more of a "maybe if you're desperate" kind of session. But it's a glimmer.
Then on Saturday, September 5th, the morning looks even better. The wind turns glassy from the west, with a 2ft SSE swell. The conditions are described as "glassy," which is a major positive. The combined energy is only 16 (weak), so the waves will be tiny, but for a beginner or someone with a longboard, it might be the only window of the whole forecast.
After that, it's back to the same old story for the final week. Small, weak swells, onshore winds, and poor conditions right through to Monday, September 7th. It's a long, dry spell.
The only real standout, if you can call it that, is the Saturday morning, September 5th. With glassy conditions, even a tiny 2ft SSE swell will be rideable for those on the right gear. But don't expect any power; it's a weak energy (16) affair.
Stay patient, folks. The ocean will come back to life eventually.
Rusty.
