The Lowdown
Alright, Rusty here. Let’s break down the next 16 days for the surf.
We’ve got surf on the table right from the start. The main event is Quatro-Once (411) – a consistent point break that loves a south-southwest swell. Water temp is about normal for this time of year.
The week opens Monday, August 24th with tiny 2ft groundswell from the SW, a long 18-second period, and zero wind – glassy as can be. The combined energy is weak (368), but for a beginner-friendly point, that’s a clean, fun little session. The glass holds through Monday afternoon and into Tuesday afternoon, with the same 2ft SW swell (16-second period, energy 271). Still small, but clean.
Wednesday morning the 26th has a light cross-off breeze from the east, 2ft SSW swell, 15-second period, energy 247. Clean. Thursday morning the 27th is similar: 2ft SW, 18-second period, cross-off wind, energy 241. Clean and small.
Friday, August 28th is where it picks up. The swell hits 2ft SW, 19-second period, energy 462 in the morning, then 2ft in the afternoon with energy 618. That’s moderate to strong energy, and the wind is light cross-off. Clean, building, and that long period means groundswell – perfect for a point.
Saturday the 29th sees a jump to 4ft SW in the morning, 5ft in the afternoon, 16-second period, energy 915–1059. That’s strong energy, but the wind turns cross-on and onshore, so it’s a bit lumpy. Sunday the 30th is similar: 5ft SW, 14-second period, energy 913–912, but again cross-on wind. Messy but surfable.
Monday, August 31st is a gem. The swell drops to 4ft SW, 13-second period, and the wind is glassy – zero wind in the morning, energy 551. The surface is perfect. The afternoon gets a little cross-on, but the morning is a true standout.
Tuesday, September 1st, has 3ft SW, 12-second period, light cross-off wind all day, energy 394–511. Clean and fun.
Wednesday, September 2nd, the swell drops to 2ft SW, but the period jumps to 18 seconds, with glassy morning wind, energy 567. That’s a long-period groundswell, and glassy – a treat for experienced surfers, though small.
Thursday, September 3rd is another big one. Morning: 4ft SSW, 13-second period, glassy, energy 841. Afternoon: 3ft SW, 19-second period, glassy, energy 970. That’s a very long period, and the surface is like glass. Unreal conditions for a point break.
Friday, September 4th, swell builds to 4ft SW (18 seconds, energy 1247) in the morning, then 5ft SW (17 seconds, energy 1584) in the afternoon. Very strong energy, but the wind is cross-on in the morning and onshore in the afternoon – lumpy.
Saturday, September 5th morning is the crown jewel. 6ft SW swell, 16-second period, glassy wind, energy 1544. That’s very strong energy, glassy, and perfect for experienced surfers. The size is over 5ft, so it’s expert territory, but at a point break with that long period, it’s a dream. The afternoon gets onshore wind and messy.
Sunday, September 6th, has 5ft SW, 15-second period, glassy all day, energy 898–873. Clean and consistent. Monday, September 7th, is also glassy, with 5ft SW, 15-second period, energy 960–939. Perfect.
Tuesday, September 8th, ends the window with 4ft SSW, 14-second period, glassy morning, energy 836. Clean and fun.
The best on offer is Saturday, September 5th morning – 6ft SW, very strong energy, glassy, and a point break that loves that direction. It’s a standout. Second best is Thursday, September 3rd – glassy, long period, clean all day. For beginners, Monday, August 31st morning is the pick – small, glassy, and safe.
Expect crowds at Quatro-Once – it’s a popular spot, and with these conditions, it’ll be busy. But the wave quality is worth it.
Keep an eye on the sky – forecasts can change, but this stretch looks solid.

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.
