The Lowdown

Alright folks, Rusty here. Let’s have a good look at what’s coming our way for the next couple of weeks.

Right off the bat, we’ve got a flat spell. For the first few days, honestly, it’s a write-off. We’re looking at a stretch from Monday the 17th through to about Wednesday the 19th with nothing but weak, onshore-crumbled slop. The wind is blowing cross-on from the ESE at 15 to 25 km/h, and the swell is under 4 ft with shocking periods down to 5 seconds. There’s just no push to it. You’d be better off waxing your board and staying home.

We finally see a tiny glimmer on Thursday morning the 20th. Akabane Long Beach goes glassy, winds drop to zero. But look – it’s only 1 ft of swell. Period bumps up to 10 seconds, and the combined energy is only 75 – that’s barely a ripple. You could get a little knee-high slider if you’re desperate, but it’s not worth paddling out for. The water temp is sitting at 81°F, which is normal for this time of year.

Friday the 21st and Saturday the 22nd see a little more size come in – around 3 ft to 4 ft – but the wind stays a problem. It’s cross-on or onshore, and the conditions are just choppy and bumpy. The energy picks up to 320 on Saturday (moderate), but the quality isn’t there. It’s frustrating because you can see a bit of swell, but the wind ruins the party.

Now, the standout window. The morning of Tuesday the 25th of August is where it gets interesting. A solid 8 ft groundswell from the SSE, with a long period of 15 seconds, rolling in. The wind shifts light from the west, making it a clean, cross-off flow. Combine that with very high energy – 3465 – and you’ve got excellent, powerful waves. This spot is very consistent and exposed, and the optimum swell direction is SSE, so this is a direct hit. The difficulty is intermediate, so it’s not for beginners, but intermediate and up are in for a treat. Be aware, this is a beach break, and a long-period swell like this can make things a bit lined-up and straight, but the quality is undeniable. Crowds are often here, so expect company.

After that, from Wednesday the 26th onward, the swell stays chunky, but the wind turns messy again. We’re looking at 8 ft to 12 ft waves, but the cross-on winds make it choppy and hard to read. The energy is still strong, hitting over 3000 on Wednesday morning, but the onshore flow kills the chance for perfect waves. By the 27th and 28th, the size gets to 12 ft (only for experts), and then we see another massive spike coming.

Check out the end of the run: Monday the 1st of September morning. Glassy conditions again with light WSW wind, and a huge 20 ft SE groundswell with an 18-second period. The combined energy is astronomical at 20373. However, the file warns the swell is too big for this break. That’s massive, powerful, and dangerous – definitely only for the most experienced charger with a big-wave gun, and even then, you need to know what you’re doing. The Tuesday the 1st of September morning is also glassy with 15 ft, but again, it’s a warning. The size is beyond what this locale can handle comfortably.

Best bet on the whole forecast: Get on the Tuesday morning, the 25th of August at Akabane Long Beach. It’s the only day where the size, wind, and energy all line up for a proper session. After that, it’s a circus of big, messy, or oversized swell.

Stay tuned, and keep an eye on these long-range signals – they can shift.

Rusty.
