The Lowdown
G’day, it’s Rusty.
Alright, let’s break down this stretch at La Boca Con Con. Overall, it’s a mixed bag—plenty of clean mornings but plenty of choppy afternoons too. You gotta be a morning surfer this fortnight.
Wednesday, September 9th, is where it starts. Waves around 3ft from the southwest, 12-second period, glassy with a hint of offshore wind first thing. Moderate energy at 414, and the water’s 58°, a touch warmer than usual for this time of year. The afternoon blows up with that cross-on breeze, so get out early.
Thursday and Friday mornings keep the same vibe: 3ft of SW swell, clean, light winds. Friday morning is especially clean with a light cross-off. Crowds are sometimes a factor here, but it’s a friendly break.
Saturday, September 12th, is a real standout. Morning brings 6ft of SW swell, clean cross-off winds, and the energy’s pumping at 571. That’s solid, punchy surf—still okay for a confident beginner, but more fun for those who can handle a bit of push. The afternoon turns to chop, so don’t miss the window.
Then we hit a lull. Sunday the 13th is tiny, just 2ft, with a long 18-second period that makes it weird and inconsistent. Not worth the paddle.
Monday, September 14th, is another cracker. Morning has 4ft of SW swell at 15 seconds, offshore winds, and a combined energy of 885—that’s strong. Very good, clean surf. The afternoon gets cross-shore and messy, but that morning session is gold.
Tuesday the 15th is still okay, 4ft of WSW swell, glassy and calm. Then it drops off. The middle of the week is flat and choppy, nothing until Friday the 18th, when we get 3ft back with clean offshore winds. Moderate energy, nothing special.
Now, the big one: Saturday, September 19th. Morning brings 6ft of SW swell at 10 seconds, light cross-off winds, and energy at 702. That’s a proper session—clean, powerful, and a lot of fun for anyone comfortable in head-high waves. Sunday the 20th keeps it going with 5ft, glassy early, also looking really good.
Monday the 21st is another one to mark: 5ft of SW swell, no wind, glassy all morning. Clean and consistent.
After that, it fades again. Small waves through the rest of the week, 3ft to 5ft, with the standout days clearly being the 19th and 20th. The long-range stuff shows a bit of energy for the 23rd, but that’s far out—promising but not certain.
Bottom line: chase the mornings, especially the 12th and 14th, and go all in for the 19th and 20th. The afternoons are mostly a write-off.
Stay salty.
Rusty.
