The Lowdown
Alright folks, Rusty here with a look at what’s shaping up for Quatro-Once (411). This spot is a consistent point break that’s good for beginners, exposed to the swell, and loves it from the SSW.
Right out of the gate, the water is sitting at a warm 85°, which is a touch warmer than normal for this time of year, so you're getting a nice little tropical bath.
The forecast kicks off on Wednesday the 19th, but don’t get too excited. That afternoon's wind is a cross-on mess from the WSW, and the 3ft SW swell has us waiting for better.
Thursday morning the 20th is where we get our first real taste. The wind swings offshore from the NNE at just 6 mph and we’ve got clean 3ft SW swell running. Wave energy is moderate (385), and the setup is nice and clean. It’s not big, but it's a nice little morning session to get the arms loose.
Friday the 21st morning is the first real standout for the near-term. Glassy conditions with a very light SE breeze, 5ft of SSW groundswell ticking in at an 11-second period, and a combined energy of 535 (moderate). That’s a fun, clean point break wave. This is the call for the early birds this week. The sets will be nicely formed.
We hit a bit of a flat spell through the weekend and into the start of the next week. The mornings on Monday 24th and Tuesday 25th, and Wednesday 26th offer small, glassy 2ft SW or SSW swells, but it's those long period swells (15-18 seconds) that make them a bit more interesting. The wave energy dips to the 200s, so it’s not punchy, but if you’re refining your footwork on a log, it’s a clean window to do it.
Now, looking further ahead, there are two absolute bangers on the horizon. Saturday the 29th morning is a massive standout. We’re talking 5ft of SW swell with a combined energy reading of 1457. That’s strong to very strong energy. The wind is glassy from the SSE. This is the big one. It’s right at the limit for a beginner, so it's an expert session with proper walls. That is the one to circle.
Sunday the 30th morning is nearly as good – another 5ft of SW swell (1256 energy) and glassy from the ESE. Back-to-back weekends of quality. Neither of these are huge, but that energy number indicates it's packing a serious punch for a point break. Long period (15-17s) means longer waits for the bigger sets, but when they come, they will stand up nicely on the point.
Moving into the final days of the forecast, Tuesday the 1st of September brings clean, glassy conditions with 4ft SSW swell. The wind drops to completely calm in the morning, and the afternoon stays glassy from the east. That’s a beautiful, clean day. The 13-second period keeps the waves fat and fun.
Wednesday the 2nd morning is a clean cross-offshore from the east, with 4ft SW swell, and Thursday the 3rd morning offers clean offshore 3ft SSW swell from the NE. Both are solid options for the intermediate.
Overall, we’ve got a bit of a gap over the weekend and early next week where it’s small, then the real pulse comes in late next week. Don't sleep on Friday morning the 28th either – glassy and 3ft SW, but that 20-second period and 509 energy is a sign of things to come. As that Saturday the 29th gets closer, check the local forecast because that is the best on offer – a true standout session for experienced surfers on a point break. The following Tuesday and Wednesday also look like absolute gems for a clean, medium-sized swell.
Rusty.

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.
