Quatro-Once (411) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. We’ve got a solid run of surf lined up at Quatro-Once (411) – a consistent point break that’s beginner-friendly and exposed to the open ocean. The water is sitting at 85°, which is a touch warmer than usual for this time of year, so you can leave the thick wetsuit at home.

The action kicks off Saturday morning, August 8th, with a clean 4ft SW groundswell rolling in at a long 16-second period. The combined energy is moderate (757), and with a light offshore breeze from the north, it’s going to be glassy. This is a great, user-friendly swell to start the weekend. Saturday afternoon stays clean with similar 4ft SW swell and light offshore winds, though there’s a risk of thunderstorms later. Sunday, August 9th, continues the trend with a 4ft SSW swell, 14-second period, and moderate offshore NE winds keeping things tidy. The energy eases slightly (607), but it’s still very good.

Monday morning, August 10th, sees a drop to 3ft SSW swell, but with gentle offshore winds it’s clean and fun for the smaller gear. The energy is weaker (352). By Monday afternoon, the wind swings onshore and the quality takes a hit. Tuesday, August 11th, offers a nice morning session with 3ft SW swell and a cross-offshore breeze, but the real standout is Tuesday afternoon. We get glassy, dead-calm conditions, a 3ft SW swell, and the period jumps to an impressive 18 seconds. The combined energy bumps up to 880, which is strong. This is a classic point break swell – long lines, clean, and the long period will grind nicely along the point. Wednesday morning, August 12th, is also glassy with a 3ft SSW 16-second swell, but the afternoon turns onshore and messy.

We hit a bit of a lull on Thursday, August 13th, with smaller 2ft swell and partly onshore winds. The surf is small and weak. Friday, August 14th, morning brings a surprise: a 4ft SW groundswell with a 19-second period, combined energy at 880, and glassy conditions. That’s a beautiful, long-period swell that will wrap perfectly into the point. The afternoon sees onshore wind, but the morning is a gem.

Now, the true standout of the entire forecast is Saturday, August 15th. The morning delivers 4ft SW swell, a 16-second period, and powerful combined energy of 1075 – that’s strong. It’s glassy, clean, and the size is perfect for experienced surfers, pushing into the bigger range. This is the best swell of the run. Sunday, August 16th, holds strong with 4ft SW swell in the morning, cross-offshore winds, and energy at 770, then a similar afternoon. The following week sees a gradual drop in size but still plenty of clean, rideable waves, especially on Tuesday, August 18th, with 4ft SW swell and clean conditions (energy 811), and Wednesday, August 19th, with glassy conditions in the morning and calm winds in the afternoon.

The final weekend, August 22nd and 23rd, fades to smaller 2ft to 3ft swell with long periods, mostly glassy in the mornings. It’s tail-end fun for the longboard or a small wave board.

If you’re picking one session, make it the morning of Saturday, August 15th – that’s the big one. For a long, clean grind, the Tuesday afternoon glass-off on August 11th with the long period is also a beauty. The consistency here is solid, so don’t sleep on it.

Rusty.
