The Lowdown
Alright, Rusty here. Let’s have a look at what’s ahead for Quatro-Once (411).
Right off the bat, we’ve got a solid run of surf starting Monday afternoon. The water’s sitting at 85° – a touch warmer than normal for this time of year, so the first session will feel like bathwater. That’s a nice bonus.
Monday afternoon kicks things off with a clean 4 ft SW swell, period 14 seconds, with a light cross-off breeze. That’s proper groundswell, and the condition is clean. The combined energy is moderate at (775), so there’s enough push for a longboard or a mid-length.
Tuesday morning is the standout early in the week. The swell drops a touch to 3 ft, but the period jumps to 18 seconds – that’s a long-period groundswell running from the SSW. That kind of period will wrap nicely into a point break, and with a light NE cross-off, it’s going to be clean, lined-up, and consistent. Combined energy hits (800). This is the best morning of the first few days for sure.
Tuesday afternoon stays good – same size, 13-second period, still clean. Then Wednesday morning the wind swings onshore from the SW, and the quality drops off. The wind stays on or cross-onshore through Wednesday afternoon, making things a bit bumpy. Not worth chasing.
Thursday morning, 10 September, turns it right back around. Glassy conditions, 4 ft SW swell at 15 seconds – that’s a dreamy morning window. Combined energy climbs to (951), so there’s proper weight in the water. If you can get out then, do it. The afternoon gets a light cross-onshore, but the morning is the pick.
Friday 11 September is the true standout of the whole forecast. Friday morning sees 5 ft SW swell, 16-second period, combined energy of (1004) – that’s the highest we see in the run. And the wind is a light easterly cross-off, so the faces will be clean. This is excellent surf for experienced surfers. The swell is over 4 ft but under 8 ft, so it’s not just for experts, but the power and length will push you. This is the session to circle. Friday afternoon still clean and good, but the morning is the magic hour.
Saturday 12 September morning is glassy, 4 ft SW, 14-second period – another clean, fun day. Size is a little smaller, but the conditions are pure. From there, the swell slowly eases into Sunday and Monday, with clean or glassy mornings, but the size drops to 3 ft and below. Still fun for a log, but losing steam.
Now we hit a bit of a gap. From Monday 14 September afternoon through to Tuesday 16 September morning, the wind turns messy, the swell stays small, and the quality is marginal. That stretch of a day and a half is worth skipping unless you’re desperate.
Wednesday 16 September morning picks back up – 4 ft SW swell, 16 seconds, clean cross-off wind. Combined energy at (696). That’s a nice little late window after the lull. Thursday 17 September is also clean and glassy, 3 ft, 14-second period, good fun.
Friday 18 September afternoon the wind swings onshore again and the surf turns poor. That lasts through Saturday with some glassy mornings but very small waves (2 ft at 19-21 seconds). That long period on tiny swell will be hard to ride unless you’re at a very sensitive point break.
Sunday 20 September through Tuesday 22 September – the swell tries to build back to 3 ft with long period SW, but the wind is mostly onshore or cross-onshore, and most of those slots are marginal or poor. A couple of glassy pockets on Tuesday morning (3 ft, 16 seconds) but nothing to get excited about.
Overall, the best on offer is Friday 11 September morning – that’s the session with the most size, the cleanest wind, and the highest energy. Thursday 10 September morning is a close second – glassy, solid, and long-period. Everything else is fun for a paddle, but those two days are the standouts.
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.
