The Lowdown
Alright, Rusty here. Let’s talk about Quatro-Once (411). This stretch is serving up a solid run of south-west groundswell, and for a point break, that’s a beautiful thing.
Water temp is 85°F, a touch warmer than usual for early September – you’ll be fine in boardshorts or a light top.
We start Wednesday morning, September 2nd, with a clean 3ft SW swell at 13 seconds. A light 3 mph cross-off breeze from the east keeps the surface tidy. Combined energy is moderate at 595. By the afternoon, the wind goes dead calm – glassy – and the swell drops to 3ft but the period stretches to 17 seconds. That’s proper groundswell energy, and with glassy conditions, it’ll be super clean. Good for beginners at this size.
Thursday the 3rd is more marginal. A light cross-on breeze and a 2ft SW swell (16 sec). Energy is 702, but the wind angle isn’t helping. Afternoon stays similar.
Friday the 4th is where it starts to cook. Morning sees the swell building to 4ft from the SW, 17-second period, with a light cross-off breeze. Clean, combined energy hits 1072. By the afternoon, wind goes glassy, and the swell pushes to 5ft at 17 seconds. Energy jumps to 1348. This is excellent, punchy point-break surf for experienced surfers.
Saturday the 5th is the absolute standout. Morning delivers a solid 6ft SW swell at 16 seconds, glassy conditions with just 3 mph from the southeast. Combined energy is 1592 – strong, powerful stuff. It’s getting big for beginners – over 5ft – but for anyone with a bit of experience, this is the session. Afternoon stays glassy with 5ft. Crowds are possible, so get in early.
Sunday the 6th holds with 5ft in the morning (15 sec, 972 energy) and clean cross-off wind. Monday the 7th starts glassy with 4ft. Tuesday the 8th offers a glassy 3ft SSW swell with an 18-second period – long lines but small.
Into the second week, the pattern holds but the size fades. Wednesday the 9th has glassy 3ft SW (16 sec, 822 energy). Thursday the 10th is another little gem: glassy all day, 4ft SW in the morning (15 sec, 1005 energy) – excellent for experienced surfers. Friday the 11th stays clean with 4ft SW (16 sec, 837 energy) in the morning.
After that, from Saturday the 12th through Thursday the 17th, it drops to 2ft to 4ft, with periods mostly 13-16 seconds. Combined energy dips below 500 often. Wind is a mix – some glassy, but plenty of cross-on and onshore slop. Not worth chasing unless you’re on a log.
If you’ve got one day to paddle out, make it Saturday the 5th. If you can’t, Friday the 4th and Thursday the 10th are both excellent backups.
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.
