The Lowdown
Alright folks, it’s Rusty here. Let’s get straight into it for our spot, Quatro-Once (411). This is a consistent point break that’s a good starter for beginners, and it’s exposed to a SSW swell. The water temp here is running about average for this time of year, nothing wild to report.
The forecast starts off quiet but with some real diamond potential building through next week. The energy is weak at first - that combined swell energy is sitting around 257 (moderate) - but the quality is high early on.
Tuesday morning, the 25th of August, we’ve got a glassy 2ft SSW groundswell rolling in with a very long 16-second period. That long period means better shaped waves and longer lulls between sets, making it easier to paddle out. It’s clean as a whistle with glassy conditions. This is a solid little session for the learner crew. The afternoon turns onshore though and gets messy.
Wednesday morning the 26th keeps that same glassy feel with 2ft SSW swell and a 15-second period. Nice and clean again. Thursday the 27th stays in the same vein – glassy both morning and afternoon with 1-2ft SW swell and a long 18-second period. Clean and easy, but small.
Now Friday the 28th, we see the combined energy jump to 475 (moderate) with a 2ft SW swell and 19-second period. That’s a very long period groundswell. While it’s clean in the morning with a cross-off breeze, this kind of period can make a point break like this really shine, with proper lines. Afternoon gets a bit cross-on.
Saturday the 29th is where it starts to get interesting. Morning is glassy with 4ft SW swell at 16 seconds, and the energy leaps to 932 (strong). That’s some proper push. This is a standout morning for anyone who wants clean, fun waves. The afternoon gets a bit onshore and messier.
Sunday the 30th is the big one. Morning brings 5ft SW swell with a 14-second period. The combined energy hits 1150 (strong). That’s excellent surf for experienced surfers, but 5ft is pushing into the intermediate zone – it might be a little heavy for total beginners. Glassy conditions again. This is the best session of the entire period, hands down. The afternoon turns onshore again though.
Monday the 31st sees the swell drop back to 4ft with shorter 13-second period and cross-on winds. It’s still surfable but not a standout.
The first week of September looks promising. Tuesday the 1st has a calm, glassy morning with 3ft SW swell at 12 seconds – clean but a little short period. Wednesday the 2nd is a belter: glassy both morning and afternoon, with a morning of 3ft SSW at 13 seconds and an afternoon of 2ft SW with a very long 17-second period. That afternoon session is going to be lined up and clean.
Friday the 4th is another huge standout. Morning delivers 4ft SW swell with an 18-second period, glassy, and the energy is 1156 (strong). That’s expert-grade conditions. The next morning, Saturday the 5th, keeps the party going with 5ft SW swell at 16 seconds and clean cross-off winds, energy at 1318 (strong). These two mornings are for the experienced crew only – that’s big, powerful groundswell with plenty of push.
After that, Sunday the 6th through Tuesday the 8th hold steady at 4-4ft with 13-14 second periods. The mornings are mostly glassy or clean, offering very good conditions for the intermediate crowd. Crowds are possible here sometimes, but on these quality days, you’ll want to get there early.
Overall, the period has a slow start but ramps up beautifully. The absolute standouts are Sunday the 30th of August and Friday the 4th of September mornings. If you can only paddle out once, make it one of those. But honestly, from the 29th onward, there’s plenty to keep you smiling. Keep an eye on that afternoon onshore wind though – it’s the morning star that shines brightest here.
Later, Rusty.

Information about the Quatro-Once (411) Surf forecast
The above surf forecast table for Quatro-Once (411) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Quatro-Once (411) can be found by selecting the local surf guide option on the grey menu. Our Quatro-Once (411) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Quatro-Once (411) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
