The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of surf on the way at Quatro-Once (411). This point break is a consistent, beginner-friendly spot that’s exposed to the SSW swell, and it’s going to be the main show for the next couple of weeks. Water temp is sitting at 85°, which is a touch warmer than average for this time of year, so you’ll be comfy in boardshorts or a springy.
The first real action kicks off on Tuesday morning, 11th August. We’re looking at a clean 3 ft SSW swell with a 14-second period, and a nice offshore NNE breeze at 9 mph. The combined wave energy is a solid 500 (moderate), and it’s glassy enough to make for some fun, tidy waves. This is a great window for getting out there without the crowds being too insane – they’re only “sometimes” here, so you should find a peak.
Wednesday the 12th is a real standout. The morning turns glassy with a 3 ft SW groundswell, period bumping up to 16 seconds, and the energy jumps to 739 (moderate). The wind is dead calm – zero – so expect near-perfect, clean conditions. The afternoon stays glassy too, with a similar 3 ft SW swell at 632 energy. This is the kind of day you call in sick for.
Thursday the 13th drops a little in size, with 2 ft SSW swell, but the morning is glassy and the afternoon has a light offshore N breeze. Still good for a log or a funboard.
Friday the 14th morning is a gem. A 4 ft SW swell, 18-second period, glassy calm, and combined energy of 851 (strong). That’s a proper groundswell pumping in. The afternoon gets a bit dicey with a cross-onshore wind, so make the most of the morning.
Saturday the 15th morning is the pick of the week. We’ve got a 4 ft SW swell, 16-second period, glassy conditions, and energy readings of 1029 (strong). This is excellent for experienced surfers, but still manageable for a keen beginner. The afternoon gets a cross-onshore breeze, so again, hit it early.
Sunday the 16th sees the swell hold at 4 ft, but the wind turns onshore and the energy drops to 772. The afternoon gets messy with moderate rain and a cross-onshore wind, so Sunday is a morning-only play.
Monday the 17th bounces back nicely. Both morning and afternoon are glassy, with 4 ft SW swell, 14-second period, and energy around 550. Clean, fun waves, no crowds to speak of.
From Tuesday the 18th onward, the swell starts to ease off, and the wind gets more cross-onshore or onshore, so the quality dips. You’ll still find some clean windows in the mornings – like Wednesday the 19th morning, glassy with 3 ft SW swell – but the afternoons are mostly a write-off.
The second week, from around 20th August, the swell drops to 2 ft–2 ft, and the energy falls into the 200–400 range. There are still some glassy mornings, like Friday the 21st morning with 2 ft SW swell at 16 seconds, and Saturday the 22nd morning with a light offshore NNE breeze, but it’s smaller and less consistent. The real standout in the second week is Monday the 24th and Tuesday the 25th mornings – both glassy, with 2 ft SSW to SW swell and 16-second periods, but the energy is low (around 280). It’s still worth a paddle if you’re keen.
Overall, the best bet is Wednesday the 12th through Saturday the 15th mornings. The peak of the swell hits Saturday the 15th morning – that 4 ft SW groundswell, glassy, strong energy, and a point break that loves that direction. Beginners will be fine on the smaller days, but anything over 5 ft might be a bit much for a total newbie.
Rusty.

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.

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.
