The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
We’ve got one spot lighting up the 16-day window: Quatro-Once (411). It’s a consistent point break that’s exposed to the south-southwest, and the optimum swell direction is SSW, so when the swell lines up, it can be a gem. The water temp is about average for this time of year, nothing too unusual there.
The first good surf kicks off Monday morning, August 10th. We’re looking at a clean 3ft SW groundswell with a solid 13-second period, and a light NNE offshore breeze. The combined energy is moderate at 536, so it’ll have some push. The conditions are glassy and clean, making it a great session for beginners and up. Keep an eye out for thunderstorms later though.
Tuesday morning, August 11th, is a standout. The swell is 3ft from the SW, but the period jumps to 14 seconds, and we’ve got glassy conditions with a light NE breeze. The energy is back up to 500. This is the kind of morning where you’ll be trading waves with a smile.
Wednesday, August 12th, stays good with a glassy start and a 3ft SSW swell at 16 seconds. The energy is a solid 689. It’s calm, clean, and the point will be working nicely.
Now, Thursday and Friday, August 13th and 14th, see a drop in size to 2ft, but the wind stays light and glassy at times. The energy drops to around 300, so it’s slower, but still surfable for the patient ones.
Then we get a nice pulse. Friday morning, August 14th, sees the swell jump to 4ft from the SW, period 18 seconds, and glassy conditions. The energy is up to 852. That’s a proper long-period groundswell, and at a point break, it should wrap in beautifully. The morning is the pick, as the afternoon gets a little cross-onshore.
Saturday, August 15th, the swell builds to 4ft from the SW, but the wind turns onshore or cross-onshore, so the quality drops. The energy is strong at 1124, but it’ll be a bit lumpy. Still, for the more experienced, there’ll be some power.
Sunday, August 16th, is another gem. The morning is glassy with a 4ft SW swell at 15 seconds. The energy is 711. Clean, solid, and a great way to start the day.
The run from Monday, August 17th, through to Thursday, August 20th, is a bit mixed. The swell stays around 3ft to 3ft, but the wind is mostly cross-onshore or onshore, so the surface gets messy. The energy is moderate, around 400-800. It’s not a write-off, but it’s not the best of the window.
Then we get a late-summer treat. Saturday morning, August 22nd, the swell drops to 2ft, but the period is a huge 21 seconds. That’s a very long-period groundswell. The wind is light and cross-offshore, making it clean. The energy is moderate at 589. At a point break, those long lines will stand up nicely.
Sunday, August 23rd, is a delight. Glassy conditions, a 3ft SW swell at 19 seconds. The energy is 847. That’s a beautiful, clean, long-period swell. The point will be reeling. It’s the best of the far-out forecast.
The final few days, Monday, August 24th, and Tuesday, August 25th, stay clean and glassy with 2ft to 2ft swells and periods around 16-18 seconds. The energy is moderate, around 440-579. It’s a gentle, fun end to the outlook.
The best on offer without a doubt are Tuesday morning, August 11th, and Sunday, August 23rd. Both have glassy conditions, solid groundswell, and the point will be peeling. The 23rd especially has that long-period magic. Don’t sleep on it.
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.
