Quatro-Once (411) Surf Forecast and Surf Report

G'day, Rusty here. We've got a solid run of surf lining up at Quatro-Once (411), a consistent point break that’s exposed to the dominant south-west groundswell. The water’s sitting at 85°, a touch warmer than usual for this time of year, so you won't be needing a thick suit.

The action kicks off Saturday morning, the 29th of August. We're looking at glassy 4ft SW groundswell with a long 16-second period – that's proper groundswell energy, and the combined energy is a strong 935, so you'll feel the push. This is a standout window; it's clean, it's pumping for a point break, and while it's manageable for beginners, the long period will really shine with lined-up walls. Saturday afternoon holds the same energy, building to 5ft and even stronger energy at 1061, still glassy – that's your best bet of the whole weekend.

Sunday the 30th keeps it going. Morning sees 5ft of SW swell, 14-second period, combined energy at 1037, and glassy conditions – a bit bigger, so it's more for the keen crew. The afternoon gets a little onshore, so quality drops.

Monday the 31st settles back to 4ft, still SW, but the glassy conditions return for both the morning and afternoon sessions. It's not huge, but the energy is still moderate at 548 and 534, and the clean conditions make it a very good, cruisy option.

From Tuesday the 1st of September through to Wednesday the 9th, the pattern is consistent: solid SW groundswell in the 3ft to 5ft range, with periods mostly between 12 and 18 seconds. The mornings are often clean or glassy, making for good sessions. The standout morning here is Friday the 4th – 4ft, SW swell, 17-second period, 1072 combined energy – but it's onshore. For the cleanest wave, look to Thursday morning the 3rd: 4ft, SW, 12-second period, 822 combined energy, with very clean cross-offshore winds.

A true highlight pops up on Sunday the 6th of September. The afternoon session delivers 5ft of SW groundswell, 14-second period, combined energy at 1146, and glassy conditions – that's a powerful, clean session for experienced surfers. Another beauty is Thursday the 10th of September afternoon: 4ft, SW, with a very long 17-second period, glassy, and energy at 1120.

From the 11th of September onward, the swell starts to taper. Friday morning the 11th is still worth a paddle with 4ft, very long 16-second period, glassy and 901 energy, then by Sunday the 13th it drops to 3ft and 2ft with onshore or cross-onshore winds. The run is basically done after that.

The absolute pick of the 16-day window? Saturday morning the 29th of August and Sunday afternoon the 6th of September – both glassy, strong energy, and lined-up groundswell at a point break. If you can only paddle out once, make it one of those.

Rusty out.
