The Lowdown
Alright, let’s get into it. We’ve got a solid run of surf on the cards for Quatro-Once (411) over the next couple of weeks. It’s not going to be huge, but there’s a consistent pulse of south-west groundswell and plenty of windows with clean, glassy conditions. The water temp is sitting pretty much average for this time of year, so nothing to worry about there.
The first standouts are right at the start. Wednesday morning kicks things off with a clean 3ft SW swell at 16 seconds – that's some proper long-period groundswell. The wind is a light easterly, keeping it glassy. This is a point break, so that long period is going to wrap in nicely. Thursday morning steps it up slightly to 4ft SW at 15 seconds with the same glassy vibe, and the wave energy is solid. Friday morning is also worth a mention, with 4ft SW and a cross-off breeze keeping things clean. We’re looking at some fun, user-friendly waves here – great for a beginner.
The weekend sees a slight drop in size and the wind goes a bit more cross-shore, but Saturday afternoon and Sunday morning still have some clean, small waves around the 3ft mark. It's more of a longboard or funboard kind of vibe. The swell energy is tailing off into the moderate range.
There’s a dip early next week, with the swell dropping right down on Monday, but there’s a nice pulse showing for Tuesday. Tuesday morning and afternoon both show a return to 3ft with the wind going glassy again – that afternoon session has a nice 18-second period groundswell, so it’s got some push behind it. That’s looking like one of the better options for the week.
After that, the middle of next week gets a bit messy. There’s still wave energy around, but the wind starts to shift more onshore and it gets choppier, especially by Friday afternoon when it’s blowing 12 mph from the west-southwest. That’s one to skip.
We then hit a quiet patch for a few days, with smaller, less consistent surf and more average conditions. Not a total flat spell, but nothing really worth getting excited about until the following Sunday. Sunday the 20th looks interesting again – a 2ft SW groundswell but with a super long 19-second period and glassy conditions. It’s small, but it’ll have some serious energy behind it. Then Monday the 21st also shows promise with 3ft SW at 18 seconds and a glassy morning. Good chance of some clean, lined-up waves pushing through.
The real wildcard is right at the end of the window. We’re looking at a bigger pulse on Wednesday the 23rd, with a 7ft SW swell. The catch is that the period drops right down to 7 seconds – that’s a short-period windswell. It’ll be a bit messier and more challenging. It’s big enough to be pushing it for beginners, but for more experienced surfers, there could be some power in it. Thursday the 24th keeps some size at 6ft, but still with that short period, so it’ll be a bit crumbly. It’s a week and a half away, so treat that one as promising, not guaranteed.
Overall, the best bets are the Wednesday and Thursday mornings right off the bat, and then that Tuesday session the following week. The point setup at Quatro-Once (411) is the place to be. Keep an eye on the winds, though – when it goes onshore, the quality drops off fast.
