The Lowdown
Alright, Rusty here. Let's look at the upcoming surf.
We’ve got a solid run starting this Friday, September 4th, at Quatro-Once (411). This is a consistent point break that’s beginner-friendly, so it’s a good spot for a range of crew. The water’s at 84°, which is a touch warmer than normal for this time of year – feels like a bath out there.
Friday afternoon kicks off with a 5ft swell from the SW, with a long 17-second period. That’s proper groundswell energy, and with combined energy reading 1332 (strong), it’s got some grunt. The wind is light and onshore, so it’ll be a bit bumpy, but it’s surfable. The real standout hits early Saturday morning, the 5th. The swell bumps up to 6ft from the SW (16 seconds), and the wind is dead calm – glassy conditions. Combined energy jumps to 1592 (very strong). This is the top of the forecast, no question. The wave direction matches the optimum for the break, and with clean, glassy surfaces, experienced surfers are going to have a field day.
Saturday afternoon gets a bit tricky with a risk of thunderstorms and onshore wind, but the swell holds at 5ft. Sunday morning, the 6th, is also a beauty: 5ft from the SW, 15-second period, and glassy conditions with a light ESE breeze. Combined energy is 893 (moderate). It’s clean and very surfable.
Monday the 7th morning stays clean with a glassy 4ft swell, but the energy drops a notch (768). From Tuesday morning the 8th through to Thursday morning the 10th, we see a pattern of smaller, glassy mornings: swell around 3ft to 4ft, with periods between 14 and 18 seconds. These mornings are clean and good for a longboard or a funboard session. The combined energy stays in the moderate range (500-900).
By Friday the 11th and into the weekend, the swell becomes more inconsistent, with heights around 3ft to 4ft, but wind conditions become less reliable – cross-shore and onshore breezes messing with the surface. The combined energy drops to the 500-700 range (moderate). It's still surfable, but not as clean.
From Monday the 14th onward, we hit a lull. Swell drops to 1ft to 3ft for several days. There’s a brief uptick on Tuesday the 15th morning with a 3ft SSW groundswell (12 seconds) and glassy wind, giving a clean but small window. The combined energy sits around 508 (moderate). After that, it’s mostly small (2ft to 3ft) and onshore winds dominate, making for rough conditions. By the 18th and 19th, it’s pretty poor with strong onshore breezes.
Overall, your best bet is Saturday morning, September 5th, at Quatro-Once (411). That 6ft SW groundswell with glassy conditions and strong energy is the clear winner. Sunday morning and Tuesday the 15th morning are decent secondary windows, but nothing tops that Saturday session.
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. 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.
