The Lowdown
Alright folks, it’s Rusty here with a look at the next couple of weeks.
We’ve got a solid run of surf coming up at Quatro-Once (411). The water is sitting at 85.3°, which is a touch warmer than normal for this time of year, so you might not even need a spring suit for a session.
The first real action kicks off on Thursday afternoon, the 16th of July. We’re looking at a clean 3.6ft SSW swell with a period of 13 seconds. The wind is light offshore from the NNE, so the surface should be smooth. The wave energy is moderate at 463, so there’s plenty of push for a beginner-friendly point break. It’s a good start.
Friday the 17th picks up the pace. The morning has a 3.6ft SSW groundswell at 14 seconds, with a gentle offshore breeze from the NNE. That’s a recipe for some beautifully lined-up waves. The afternoon holds steady with a 3.9ft SSW swell, shifting to a light cross-offshore wind from the north. Very clean conditions.
Saturday the 18th is looking like a standout. The morning has 3.9ft SSW swell, light offshore wind, and the energy is climbing to 569. Then the afternoon goes glassy with a light offshore wind from the WNW. That’s about as good as it gets for a clean, fun wave.
Sunday the 19th is a mixed bag. The morning is absolutely glassy with 3.6ft SSW swell, but by the afternoon the wind swings onshore from the SSW, making it a bit of a write-off. Enjoy the morning session.
The surf dips a little from Monday the 20th through Tuesday the 21st, with smaller 2.3ft to 3ft swells and cross-shore winds. Not terrible, but nothing to get excited about.
Wednesday the 22nd morning brings a surprise: a 4.6ft SW swell with a short 7-second period, but it’s glassy. That short period will make it a bit fat and crumbly, but it’s clean. The afternoon gets messy again.
Thursday the 23rd has a 4.3ft SW swell in the morning with a light cross-offshore wind, then the afternoon turns glassy with a tiny 1.3ft, 26-second period swell. That’s an incredibly long period; it’ll be slow and clean, but those waves will be weak and inconsistent.
Now, here’s where things get interesting. The real standout of the whole outlook is the stretch from the 24th to the 29th of July. The first week was good, but this is the main event.
Friday the 24th is a beauty. A 2.3ft SW swell with a 24-second period, glassy conditions. The energy is very high at 819, meaning those long-period lines will have some serious grunt. Perfect for a point break like this. Saturday the 25th stays clean with a 3ft SW swell and a gentle offshore breeze.
But the absolute highlight is Sunday the 26th and Monday the 27th. Sunday morning has a 3.6ft SW swell with a 19-second period and an energy reading of 1281 – that’s strong wave energy. The wind is light and variable, making for clean conditions. This is excellent surf for experienced surfers. Monday the 27th morning is even bigger, with a 4.6ft SW swell and a 19-second period, and the energy is a massive 1649. It’s glassy. This is world-class, powerful, long-period groundswell on a point break. This is the one to circle on your calendar. It’s for experienced surfers only, as it will be powerful.
The energy stays high through Tuesday the 28th (4.9ft, 18-second period, 1663 energy in the morning) and Wednesday the 29th (4.6ft, 16-second period, 1081 energy). The mornings are all glassy. The afternoons get a bit of cross-onshore wind, so get on it early.
The last couple of days of July and into the 31st, the swell backs off to 2.6ft-3.3ft, but it stays clean with glassy or light offshore winds. A nice way to end the run.
Overall, the best on offer is Monday the 27th of July morning for the biggest, most powerful, glassy conditions. The Sunday the 26th morning is a close second. Get out there.
