The Lowdown
Alright, folks, Rusty here. Let’s get into it.
The first real action on offer is at Quatro-Once (411), a point break that’s a classic beginner-friendly setup. Things kick off on Thursday the 20th of August, but don’t expect much then. The water’s sitting at a balmy 85°, which is a touch warmer than normal for this time of year, so you'll be comfortable in boardies.
The first standout window is Friday the 21st of August. We’ve got a clean 4ft SSW groundswell rolling in with a period of 11 seconds, and the wind is absolutely glassy – dead calm in the morning and glassy in the afternoon. This will be clean as a whistle. The combined swell energy is solid at 474, meaning plenty of push for a longboard or a funboard. Crowds can show up here sometimes, so get in early.
Saturday the 22nd still has that clean, glassy feel in the morning, but the swell drops to 3ft. It’s still rideable, just smaller. The rest of the first week is a bit of a mix – small waves and a few dodgy afternoon breezes. It’s not a write-off, but nothing to get truly excited about.
Now, Saturday the 29th of August is where it gets interesting. The morning session sees a solid 5ft SSW groundswell, period 16 seconds, with glassy conditions. The combined energy hits 1113 – that’s a strong pulse of energy. This is described as excellent for experienced surfers, but at 5ft it’s very manageable for an advancing intermediate too. The direction is bang on for this point.
The momentum carries into Sunday the 30th and Monday the 31st, with consistent 5-5ft swells and glassy mornings. But the absolute standout in the whole forecast is Friday the 4th of September. We’re looking at a 6-6ft SW groundswell, a very long 18-second period, and a clean, cross-offshore breeze in the morning. The combined energy is a whopping 2034. That’s a lot of power. The period is so long that the sets will be widely spaced, but the wave shape on this point break will be lined up and beautiful. It’s a bit heavy for beginners, but experts and confident intermediates will be in for a treat.
There is a noticeable gap in quality surf for the few days before that, but the build-up is worth the wait.
Stay stoked, and I’ll see you in the water.
