The Lowdown
Alright, folks, Rusty here. Let's have a look at what's coming down the line for Quatro-Once (411).
We've got a solid run of surf ahead, kicking off this Saturday morning. The water’s sitting at a balmy 84°, which is a touch warmer than what you'd normally expect for this time of year—not a bad thing if you ask me.
The standout session, without a doubt, is Saturday morning, the 5th of September. We're looking at a proper 6ft swell pushing in from the southwest, and the energy is cooking with a reading of (1592). That's a powerful groundswell with a 16-second period, so there's plenty of heft behind it. The kicker? Glassy conditions, absolute zero wind. It's going to be as clean as a whistle. Now, with the size over 5ft, it might be a bit of a handful for the beginners, but for anyone with a bit of experience, this is the window. Remember though, that long period groundswell can make a point break like this really stand up and offer some beautiful lines, so keep that in mind.
The morning after, Sunday the 6th, still looks very good. The swell drops a touch to 5ft, but the wind goes cross-offshore from the east at 6 mph, keeping things clean and groomed. The energy is still strong (1051). That'll be a fun session.
The surf does start to wind down through the week. By Monday the 7th, we're into 4ft territory, still clean with that east wind, but the size is dropping off. There's a real lull in the middle of the forecast. From about the 13th of September onwards, the swell gets pretty small and inconsistent, with heights mostly under 3ft. The energy drops down to low three-digit or even two-digit numbers, like (311) on the 13th. It's not a write-off, but it's definitely a quieter period where you'd be hoping for a sneaky set to make the paddle worth it.
However, there's a flicker of something interesting right at the tail end. Sunday morning, the 20th of September, shows a long-period groundswell of 2ft from the SW with a period of 20 seconds. The energy reading is (528), which for that size is telling you there's some serious power in the water, just not a lot of height. The wind is light and cross-offshore, so it'll be clean. That's one for the longboard or a fun mid-length to hunt down those long, silky walls.
So, the verdict: jump on that Saturday morning session. It's the clear winner. After that, the week has some fun, smaller waves, but there's a big stretch of flatness around the middle of the month. Don't write off that final Sunday the 20th though—it could be a quiet gem.
Stay stoked.
