The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for Quatro-Once (411). This is a point break that's exposed to SSW swell, and it’s a consistent spot that’s good for beginners. It’ll be a bit of a mixed bag over the next couple of weeks, but there are some real gems to look out for.
The water’s sitting at a toasty 85° right now, which is a touch warmer than normal for this time of year—nothing crazy, but you’ll feel it.
The run kicks off Monday afternoon, the 17th of August. We’ve got a clean 4ft SSW swell with a 14-second period, and glassy wind conditions. The combined energy is solid at 680—moderate energy, but with that long period, it’ll be nice and lined up. Expect very good surf.
Tuesday morning the 18th keeps things rolling with more 4ft SSW swell, 14-second period, and a light cross-off breeze out of the ENE. It’s clean and surfable. Tuesday afternoon drops a touch to 3ft, still clean, still good.
Wednesday the 19th morning is another glassy one: 3ft SSW, 14 seconds, glassy wind. The afternoon gets a bit iffy with onshore wind and only 3ft, so morning is the call.
Thursday the 20th morning has 3ft but the swell direction shifts slightly more southerly at 13 seconds—still clean with a cross-off breeze. Thursday afternoon bumps back to 4ft but the period drops to 10 seconds, so it’ll be a bit lumpier.
Friday the 21st morning is the standout of this first week: 4ft SSW swell with an 11-second period and glassy conditions. That’s a proper little session. The afternoon goes onshore and messy, so get out early.
Saturday the 22nd is mostly marginal—small 3ft with onshore winds, and the swell drops further through the day.
Sunday the 23rd and Monday the 24th start dropping into the 2ft to 2ft range. The period is still long (20 seconds on Sunday morning), but it’s tiny. Monday is glassy though, so you could get a fun little longboard wave if you’re keen.
Tuesday the 25th morning is still small at 2ft with a 16-second period and glassy conditions. Worth a paddle if you’re desperate, but it’s dropping.
Now, here’s where it gets interesting. Friday the 28th afternoon shows a pulse: 3ft SW swell with a whopping 19-second period and combined energy at 876—that’s moderate-to-strong. The wind is cross-shore though, so it’s not perfect.
But the real highlight of the whole run is Saturday the 29th morning. The swell jumps to 5ft SW with an 18-second period and combined energy at 1519—that’s strong energy. Wind is light cross-shore, which is okay, but it’s a lot of power. This size is getting into the expert-only zone, especially with that very long period. It’ll be breaking straight at a beach setup, so this is really a reef or point wave day. For Quatro-Once (411), being a point, that long period will actually work in your favour—nice, rideable walls. But if you’re a beginner, sit this one out.
Sunday the 30th morning stays solid: 5ft SW, 16-second period, with a light cross-off breeze out of the east. Combined energy at 1270, and it’s excellent for experienced surfers. Clean, powerful, and lined up. Sunday afternoon has 5ft with offshore NNE wind—another excellent session for the confident crew.
Monday the 31st morning drops back to 5ft with 14-second period, glassy, very good conditions. A nice way to close out August.
Tuesday the 1st of September morning has 4ft SW, 13-second period, clean cross-off wind. Still good, but easing.
So, to sum it up: the best on offer is Friday the 21st morning for a clean, fun size, and then the big energy hits on Saturday the 29th and Sunday the 30th—those are for experienced surfers only. The long-range stuff is promising but not locked in yet, so keep an eye on it.
Stay stoked,
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. If you surf the same spot (Quatro-Once (411)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
