The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Octagon House area. I gotta be straight with you – this is a grim outlook. We're looking at a 16-day window, and the first surfable day that's even worth a mention isn't until Wednesday, September 16th. That's a solid two-week gap of nothing but poor conditions. The swell is tiny, the wind is mostly onshore, and we've got a lot of risk of thunderstorms early on. It's a real dry spell.
For the first two weeks, don't bother. The combined swell energy is in the single digits and low double digits – weak, pathetic stuff. Wednesday, September 2nd through the 15th is a write-off. We're talking ankle-snappers at best with constant cross and onshore breezes making a mess of things. You'd be better off doing literally anything else.
Now, come Wednesday, September 16th, we finally get a glimmer. The morning shows a 2ft swell from the SE with a period of 5 seconds. The wind goes light from the North, giving us a clean, cross-offshore breeze. The combined energy is still only moderate at 51, but for the first time in weeks, it's clean. It's not going to be epic, but it's surfable without the chop. The water temperature is 87°, which is a touch warmer than normal for this time of year.
The day after, Thursday, September 17th, the morning is similar. A 2ft swell from the SE, period of 6 seconds, and another clean window with a light NNW cross-offshore breeze. The energy drops a bit to 32, but it's still clean. The swell is small, so it's perfect for a beginner. The break is fairly consistent, so there should be a few waves to go around, but remember, it can get crowded here sometimes.
The only real standout in this whole period is the morning of Wednesday, September 16th. It's the cleanest conditions we'll see by a long shot. The swell is small, but the light offshore wind means it'll be glassy. If you're a beginner or just want to get a wet, clean surf in, that's your window. The Thursday morning is a decent backup, but the Wednesday is the pick of a very poor bunch. For anyone else, this is a time to work on the board or go for a swim.
Rusty, signing off.
