The Lowdown
Right, grab a coffee and settle in – Rusty here with the full 16-day outlook for Quatro-Once (411).
Alright, so we’ve got a solid run of swell coming through. The water’s sitting at 86°, which is a touch warmer than normal for this time of year, so you can leave the thick wettie at home.
The action kicks off this Friday morning, July 17, with a clean 4ft SSW swell, period a moderate 14 seconds, and a light offshore breeze from the north. The combined energy reading is 514 – moderate, but it’ll produce some fun, clean lines. That quality holds through Saturday, July 18, when it gets even better. Saturday morning we’ve got 4ft swell from the SSW, 13 seconds, and the wind goes glassy from the ENE. It’s a little on the smaller side, but the surface will be like a mirror all day. This is a standout window for beginner-friendly waves; it’s consistent and clean. Expect some crowds though – it’s a known spot.
Sunday morning, July 19, remains glassy with a 4ft SSW swell and a 12-second period. The energy dips a touch (467), but still fun. By Sunday arvo, a light cross-onshore pops up, and the quality drops a notch. Monday, July 20, has a small 3ft swell, but the morning looks absolutely glassy – dead calm, which is a bonus for getting some clean waist-high runners.
Then comes a bit of a lull. Tuesday and Wednesday (21st and 22nd) drop right down. Swell sizes tumble to 2ft - 2ft, and the winds get a bit messy. Not worth paddling out for unless you’re on a foily.
Now, hold onto your board. We get a spike on Thursday afternoon, July 23. The swell period jumps to a massive 26 seconds, but the height is only 1ft. That’s a long-period groundswell with very high energy (477), but so tiny it’s almost not breaking properly. The real standout arrives on Friday morning, July 24. The swell bumps to 3ft from the SSW, still with a very long 24-second period, but the combined energy reading is a massive 1153. With a light cross-offshore breeze from the NW, this will be absolutely world-class in the water – clean, powerful, and lined up. This is for experienced surfers only; the paddle out will be tricky, but the reward is a long, walling right.
The good energy continues. Saturday, July 25, and Sunday, July 26, have 3ft to 3ft SW swells with periods of 19-21 seconds. Winds stay clean, mostly cross-offshore. The energy readings are in the 700-900 range. Another serious standout is Monday morning, July 27: 4ft SW swell, 19 seconds, and glassy conditions. That energy is 1216 – you’re looking at strong, powerful sets with excellent shape.
Tuesday the 28th and Wednesday the 29th are the peak of the second week. Swell heights hit 4ft to 5ft from the SW, periods dropping slightly to 16-18 seconds, but the energy readings are massive – 1349, 1698, and 1203. Winds are offshore or cross-offshore in the mornings, providing clean, powerful waves. This is expert territory at the top end of the size range.
We start to slowly taper off through the end of the month. Thursday 30th still has 4ft swell but the wind turns onshore in the arvos. Friday 31st and into August 1st it’s still rideable – 4ft SSW swell and clean winds – but the magic of that long-period groundswell is gone.
Overall: The standout sessions are the glassy, consistent Saturday 18th for beginners, and the long-period, high-energy Friday 24th and Monday 27th for experienced surfers looking for quality. The second week brings the biggest swell, but it’s for the crew who can handle 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.

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.
