The Lowdown
Hey, it’s Rusty again, this time in feet and knots.
We’ve got a decent run coming, with just a quiet patch right at the start. First real waves hit Sunday morning, August 23rd, so we’re good.
The spot to keep your eye on is Quatro-Once (411). This point break is consistent, open to that SSW swell, and beginner-friendly. The water’s 29° – a touch warmer than usual.
Sunday morning, August 23rd, brings a tiny 2ft SW swell, but it’s glassy with a 5 km/h ESE breeze. Wave energy is moderate (418). Small but clean. Monday morning, August 24th, is similar with 2ft SW, glassy, zero wind, energy 355. Monday afternoon gets a bit lumpy.
Tuesday through Thursday, August 25th to 27th, stay small – around 2ft to 2ft – but mornings are glassy or clean. Energy dips to 239-269. Still fun for a cruiser session.
Friday, August 28th, bumps to 2ft SW, glassy, energy at 462.
Then things get interesting. Saturday, August 29th, swell jumps to 4ft SW, but cross-on wind makes it bumpy. Energy hits 944. Sunday morning, August 30th, is the first big highlight: 5ft SW, glassy, energy at a very strong 1044 – excellent for experienced surfers. That morning is a gem for anyone comfortable on a bigger wave. Period is 14 seconds, so a proper groundswell.
Monday, August 31st, drops to a clean 4ft SW, glassy, energy 625. The rest of the first week into early September holds around 3ft to 4ft, with clean mornings.
The real standout is the final push. Thursday, September 3rd, afternoon energy surges to 1332 with a 4ft SW swell and glassy conditions – top-notch. Friday, September 4th, is the best of the whole outlook: 5ft SW, glassy morning, energy at a very strong 1834, period 18 seconds. Long lines, point break handling it perfectly – for experienced surfers only. Saturday, September 5th, keeps it going: 6ft SW, glassy all day, zero wind, energy 1841. That’s another excellent session, but too big for beginners.
After that, it eases to 5ft to 6ft with onshore winds.
So, for the best: Quatro-Once on Friday morning, September 4th, or Saturday morning, September 5th. Glassy, solid SW groundswell, very strong energy. Crowds are sometimes around, but it’ll be worth it.
Rusty.

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.

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.
