The Lowdown
Alright folks, Rusty here. Let’s have a look at what the ocean’s got cookin’ for us. It’s a bit of a mixed bag, but there’s definitely some fun to be had if you pick your moments.
Right out of the gate, we’ve got some clean, glassy conditions with a solid SW groundswell pushing in around 4ft. The energy is moderate and with a long 16-second period, this is proper groundswell. This is the kind of swell that will wrap into points nicely, and with the glassy morning, it’s going to be worth a paddle. The water temp is running about average for this time of year, so no surprises there.
That Friday morning vibe carries into the afternoon, still glassy with a touch less size but still with that long period. It’s going to be a good day to get a few waves before the weekend crew shows up.
Saturday morning at Quatro-Once (411) sees the swell dropping slightly to 3ft but it's still clean and glassy. Come the afternoon, the wind switches onshore and things get a little more challenging, so make sure you get your fill in the morning. Sunday brings a bit of a drop in size to around 2-3ft but the morning is clean with a cross-off breeze. It's still fun, just not as beefy.
We hit a bit of a lull Monday, with the swell dropping right off to 2ft, even though the period is super long. The energy is weak. It's a bit of a rest day for the waves, even if the conditions are clean.
Tuesday sees the swell start to build back.
The real standout of this whole run looks like the middle of next week. Wednesday the 16th, we’ve got a 4ft SW swell, glassy conditions and strong energy back up there. That is a recipe for some really fun, clean waves. Thursday the 17th is right there with it too, 3ft and glassy again, still with that nice long period. These two mornings are the pick of the week. After that, the swell backs off a touch for Friday but it's still clean.
Now, looking further out, there’s a promising pulse on Sunday the 20th. The swell is around 3ft, but the period jumps back up to 19 seconds and the energy is solid. With zero wind and glassy conditions in the morning, that’s going to be a day for the longboard or the fish. That could be a sneaky good one if the forecast holds.
The swell builds again for the 22nd, with 4ft at an 11-second period and a cross-off breeze, that's a fun combo. It's got the size and the wind is right, but the period is shorter, so it might not have the same push as the long-period stuff.
The last week of the run starts to get a bit iffy. The swell is still there, but the winds become more onshore and the waves get messier. The energy starts to fade and the quality drops. It’s looking like a poor end to the window, with small, wind-affected surf.
One last thing: there’s a pulse on the 26th with a 20-second period, but it's only about 2ft and the wind is junky. It’s more of a tease than a real option.
So, my call: get out there Friday morning or Saturday morning. Then mark your calendar for Wednesday and Thursday of next week – that’s your best bet for quality. And keep an eye on Sunday the 20th, that could be a fun glassy surprise.
Rusty, out.

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.
