The Lowdown
Alright mates, Rusty here. Let’s have a look at what the ocean’s got in store for us over the next couple of weeks. It’s gonna be a tale of two weeks, so get ready to wait.
The first few days are looking pretty bleak. From Tuesday the 18th through Thursday the 20th, we're looking at tiny, short-period slop. Not much energy at all, with the swell energy reading in the 29 to 371 range. It's just not worth paddling out for. You're better off polishing your board.
We finally get a pulse of proper groundswell on Friday the 21st. The morning is the pick. We're looking at clean 5ft of west-northwest swell at Ilbaritz - Edouard VII, with a glassy easterly breeze. The swell energy jumps to 484, a moderate push, and the period is a solid 10 seconds. That should give the reef some nice shape. The afternoon gets a bit choppy with cross-shore winds, so get your session in before lunch.
After that little tease, the weekend and early next week drop right back off. Saturday and Sunday have some surfable but average waves. Not much to get excited about. But the stars align again around Sunday the 30th and Monday the 31st. This stretch is looking like the most consistent and cleanest run we’ll have. Light offshore and cross-offshore winds will keep a 4-4ft west-northwest swell clean and fun. It's not giant, but it'll be quality.
Now, here’s the big one. The standout of the entire forecast is on Wednesday morning, September 2nd. This is the one to mark on your calendar. The models are pointing to a proper pulse of long-period swell—7ft of west-northwest swell at 12 seconds. The wind is forecast to be glassy, which is exactly what we want. The energy reading is a massive 1381, signalling a strong, powerful swell. This is clean, powerful, and has some serious juice. For the experienced crew, this is the session to get keen for. It’s a couple weeks out, so we’ll keep an eye on it, but the early signs are looking extremely promising. For the beginners, this might be a little too much, but for the rest of us, it's going to be a proper day at the reef.
Alright, that's it from me. Stay patient.
Rusty.
