The Lowdown
Alright, grab a coffee, let's have a look at what's comin' our way for the next couple of weeks. We're lookin' at a bit of a mixed bag, but there's definitely some windows for a proper session if you time it right. The water is sittin' right around the 64° mark, which is pretty much what you'd expect for this time of year, no crazy anomalies to talk about.
Alright, so we kick off on Thursday the 13th. Molhes de Mampituba (Rio Grande do Sul) is where it's at. Thursday morning sees a solid 6-ft swell out of the SSE with a long 14-second period, so there's proper groundswell energy pushin' through. The combined wave energy is strong at 1062. The wind is light and cross-off from the WSW, which is gonna keep the face clean for experienced surfers. This is your window, but it's a picky one – this is for the crew who know what they're doin' on a river jetty. The afternoon turns to junk, so get it while you can.
Friday the 14th is a write-off. The morning has a 12 mph cross-shore wind messing up the 6-ft SSE swell, and it only gets worse by the afternoon. Leave the board in the car.
Saturday the 15th is not for the faint-hearted. We've got an 8-ft easterly swell in the morning, but with a short 8-second period and a 16 mph cross breeze, the combined energy is a massive 1550, but the quality is poor. It's gonna be a washing machine. More of a kite-surf day than a paddle-surf day. The afternoon drops a bit in size, but the wind stays on it.
Now, here's a standout for the first week. Sunday the 16th. The morning session is clean with a 8-ft ENE swell and 9 mph cross-off winds. The energy is strong at 1167. Conditions are excellent for experienced surfers. But the afternoon... the afternoon has a 10-ft swell. That is only for the hardcore crew. The wind stays nice and cross-off, but the raw power is next level.
Monday the 17th morning is a beauty. A clean 6-ft easterly groundswell with glassy conditions, dead calm winds. Energy is moderate at 526, but the quality is what you're after. This is a great, more accessible session. The afternoon gets a bit sloppy.
The middle of the week, Tuesday the 18th and Wednesday the 19th, are mostly small and wonky. There's a tiny 3-ft swell with average winds. Not worth the paddle.
Thursday the 20th and Friday the 21st are nothing special either. The wind is mostly onshore or cross, making a mess of most waves. There's a glimmer on Friday afternoon with a 6-ft S swell and a longer 11-second period, but the cross-shore wind keeps it from being a standout.
Now, let's look further ahead. Saturday the 22nd morning is a proper gem. A small 4-ft S groundswell with dead calm, glassy conditions. It’s not big, but it’ll be perfect, clean lines. Definitely a good one for a longboard or a fish.
The next real highlight pops up a week later, on Monday the 24th of August. We’ve got an excellent morning session with a 6-ft SSE groundswell at a long 14 seconds, and light offshore winds. Energy is strong at 1188. The afternoon is even cleaner, going glassy with a 5-ft SSE swell. This is a solid day for everyone who can handle a jetty. It gets a bit blown out again on Tuesday the 25th.
Then, on Wednesday the 26th afternoon, keep an eye on it. We’ve got a standout pulse of energy: a 7-ft SE swell with a very long period of 16 seconds. Combined energy is enormous at 2544. The wind is light and cross-off. This is serious groundswell – it'll be lining up, but with that long period and big size, it's going to be powerful and best handled by the experienced crew. The river mouth might channel it beautifully. Finally, Thursday the 27th morning has another solid, clean 5-ft SSE groundswell to round things out. The last few days of the window, the 28th, fade out with small, messy windswell.
Best of the bunch? I'm calling it for Sunday the 16th morning for the raw power and good wind, and Monday the 24th for a full day of clean, a-bit-more-friendly conditions. The long-range stuff on the 26th afternoon is a promise, but it's a promise of some serious, heavy waves.
Stay safe out there.
