Quatro-Once (411) Surf Forecast and Surf Report

Alright, let’s have a look at what’s on the table for this stretch. The real standout window is gonna be from Thursday the 10th through to about Monday the 14th of September, with some clean, glassy conditions and a solid SW groundswell rolling in for a good part of that. After that, things get a bit more hit and miss, especially into the third week where the wind turns onshore and the quality drops off. But don’t worry, there’s plenty to get excited about early on.

We’re looking at Quatro-Once (411) as the go-to spot. This place is a consistent point break, exposed to that SSW swell direction and it’s been getting some nice, lined-up swell. The water temp is sitting at 85°F, about 3°F warmer than usual for the time of year, so it’s a touch warmer than normal.

Thursday, 10th September kicks off with a nice SW groundswell at 4 ft and a period of 15 seconds. That’s very long period stuff, which means proper energy, long gaps between sets, and the point setup here will handle it beautifully with clean, well-shaped waves. The wind’s glassy for both the morning and afternoon – a complete 0 mph in the afternoon with “risk tstorm” overhead, but glassy is glassy. Combined energy is 963, which is moderate, and the surf is clean and peeling. For a beginner-friendly point break with that consistency, this is a warm-up that delivers.

Friday, 11th is looking even better for the morning. Same pulse, slightly bigger at 4 ft, still 16 seconds of period, glassy with a 5 mph ENE breeze. Beautiful stuff. The score and the feel are top tier. The afternoon turns a bit cross with some SE wind coming up, but it’s still rideable.

Saturday 12th and Sunday 13th keep the trend going – drops a little in size (3 ft then 3 ft Saturday morning) but still long period SW groundswell with glassy or clean textures. The combination energy stays moderate (497 down to 367). It’s solid, consistent fun, and the crowds are “sometimes” here, so you might get a peak to yourself.

The standout of the whole forecast is probably Thursday afternoon the 10th and Friday morning the 11th. That’s the sweet spot: 4–4 ft of long-period groundswell, dead glass conditions, the swell direction matches the optimum SSW direction for the point, and the energy is carrying well. Just a beautiful run.

After the 14th, Monday morning still has a 19-second period pulse, but it’s tiny at 1 ft. Still glassy with NNE wind, so maybe a longboard session, but it’s not going to get your heart racing.

From the middle of the second week, around 15th September, we see a brief bump again Tuesday afternoon – 3 ft, 18 seconds, zero wind, glassy, energy at 645 – that’s a fun little spike. Wednesday the 16th morning also looks tidy: 4 ft, 16 seconds, glassy with a light ESE breeze.

But then after that, things get messy. From Thursday 17th afternoon through to the end of the 16-day window, the wind starts to swing onshore from the SW and WSW, the chop picks up, and the quality goes downhill. There’s a string of “poor surf conditions” from 19th September onwards, with moderate breezes and choppy water. The last few days won’t be worth paddling out for unless you’re after a challenge.

In short: Lock in Thursday 10th morning through Sunday 13th for the cleanest, most consistent, best-shaped waves. That’s the sweet spot. After that, it’s a slide into mediocrity with some onshore crud. The 3 ft 18-second pulse on Tuesday 15th afternoon is worth a quick session if you’re nearby, but the real glory is in the first four days.
