The Lowdown
G’day, Rusty here. Looks like we’ve got a solid run of clean, user-friendly surf coming our way at Quatro-Once (411). This is a consistent point break that’s perfect for beginners, and it’s exposed to the SSW swell. The water’s sitting at 85°, which is a touch warmer than normal for this time of year.
The week kicks off from Tuesday morning, September 8, with a 3ft SSW swell at a very long 18 seconds, and a gentle NNE breeze holding it clean. That combined energy reads 789 – moderate. The long period will offer smooth, well-shaped waves, though be aware of the longer gaps between sets. The point break setup here is ideal for handling that. Through Tuesday afternoon, the swell edges up to 3ft, still clean with a light N breeze.
Wednesday morning, September 9, is a standout. The swell hits 3ft from the SW, period 16 seconds, and it’s glassy with a SSW breeze at just 3 mph. Combined energy at 822 – moderate. This is about as good as it gets for a clean, cruisy session. The afternoon gets a little cross-onshore, so I’d stick to the morning.
Thursday morning, September 10, is another beauty: 4ft SW swell, 15-second period, dead calm with 0 mph ENE wind. Glassy conditions, combined energy 970 – moderate. The morning window is your best bet. Friday morning, September 11, keeps the run going with a 4ft SW swell, 16 seconds, and a light cross-offshore E breeze. Clean, punchy, and still a great size for all levels.
We’ve got a long stretch of small, clean surf through the second week, with the swell dropping to 1ft to 3ft from the SW, but still often glassy early. The period remains long, between 13 and 19 seconds, so the waves will be lined up and easy to paddle into. The combined energy drops to between 296 and 504 – weak to moderate. A few afternoons get a bit of cross-onshore wind, but the mornings consistently deliver clean conditions.
One promising session later on: Sunday morning, September 20, shows a 2ft SW swell with a very long 19-second period and glassy conditions. Combined energy 504 – moderate. It’s a smaller day, but the quality will be there for anyone on a longboard or a funshape.
The final days, September 22 and 23, see a mix of glassy starts and wind-affected afternoons. By Wednesday morning, September 23, it’s glassy again with a 2ft SW swell, 15 seconds, combined energy 348 – weak, but still a clean little wave.
Overall, the best on offer is Wednesday morning, September 9, for the glassy conditions and solid 3ft SW swell. The other standout is Thursday morning, September 10, with the dead calm and 4ft SW groundswell. Both are top-tier for this spot.
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.

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.

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.
