The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a nice run of solid, rideable surf ahead for the next couple of weeks. The first couple of days are a bit small, but we’ve got some standouts coming if you play your cards right. The water’s sitting at 85° – that’s a touch warmer than normal for this time of year, so the boardshorts will be fine.
The first real window opens up on Friday afternoon, the 28th. It’s a bit small with a 2ft southwest swell, but the period is a solid 19 seconds and it’s dead glassy. The energy is moderate (618), so it’s not going to be a monster, but with that long period and no wind, it’ll be clean. The spot here is Quatro-Once (411). It’s a consistent point that’ll handle this well. It’s not a standout, but it’s a fun way to kick things off.
Then we have a slight dip on Saturday morning the 29th – size bumps to 4ft but the tide might be iffy. But Saturday afternoon is where it starts to get interesting. 5ft of southwest swell, 16-second period, and that energy jumps to strong (1061). The wind is glassy with a slight air. This is an excellent wave for experienced folk. Still not the biggest, but clean and powerful.
Sunday the 30th is a mixed bag. Morning has 5ft but it’s a bit onshore with questionable tides. The afternoon drops back to 5ft and turns cross-onshore. It’s a bit messy, so maybe not the best day to be out.
Now, look, the beginning of the week is all about the small, glassy waves. Monday the 31st and Tuesday the 1st of September have 4ft swells, but with that 12-14 second period and perfect glassy conditions, those point break lines will be some of the cleanest you’ll see. The energy is moderate (around 466-554). Not a standout, but a very good, user-friendly wave. Good for getting the board wet.
Wednesday the 2nd is interesting. The morning is 3ft with 13-second period and E wind – glassy again. But the afternoon jumps up to 3ft with a much longer 17-second period. That long period is a big deal. The energy stays moderate (702), but those waves will have some real shape on them. It’s a bit of a sleeper.
Thursday the 3rd is similar. Morning is 4ft and clean. The afternoon drops to 3ft and turns a bit onshore. Not ideal.
Now, here’s where it gets good. Friday the 4th of September morning is a standout. The swell is 4ft, but the period is a very long 17 seconds, and the direction is pure southwest. The energy is strong at (1074). And it’s glassy. Dead flat. This is a great session. It’s a bit small for the experts, but for everyone else, it’s going to be a perfect, clean, long-period day at the point.
Then, keep an eye on Saturday the 5th of September morning. This is the punch. The swell jumps to 6ft, period is 16 seconds, and the energy is very strong (1614). It’s glassy. This is for the experienced crew – that’s over 5ft, so it’s not beginner territory anymore. But if you can handle it, this is the biggest, cleanest swell of the whole window. This is the one to circle on the calendar.
The rest of that weekend and early next week is consistent. Sunday the 6th has 5ft with glassy morning conditions. Monday the 7th backs off to 4ft. Tuesday the 8th brings in a bit of a different swell – from the SSW with an 18-second period at 3ft. Long period again, but a bit smaller.
The second week starts to firm up again. Wednesday the 9th is glassy with 4ft. Thursday the 10th is a bit cross-onshore with 4ft. But then look out for Friday the 11th of September morning. It’s back to that 4ft, with a 16-second period, but clear skies and a glassy ocean. That’s a solid one. Very promising.
Finally, Saturday the 12th at 4ft with 14-second period and a dead calm ocean. It’s a good note to end on.
So, to sum it up: get out there Friday evening if you want a clean start. But the real standouts are Friday the 4th morning for the quality and Saturday the 5th morning for the size. Keep those dates in mind. Otherwise, there’s a lot of great, groomed surf in between.
Rusty, out.

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.

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.
