The Lowdown
Alright, this is Rusty. Let's get into it.
Well, I'll be honest with you, the next week or so looks pretty flat and uninspiring around here. We've got a long quiet spell to get through before things finally wake up. The first decent chance of a wave doesn't show until Thursday the 20th, and even then, it's just a tease. After that, we're looking at another big gap of ordinary conditions until we get to the real action in the first week of September. So, patience is the name of the game.
The standout session, the one you want to circle on your calendar, is Tuesday the 1st of September at Playa de Arrigunaga. Tuesday morning looks like it could be something special. We're expecting a clean 6 ft groundswell rolling in from the NW with a period of 11 seconds. The combined energy is strong at 690, so there'll be some proper push behind those waves. The wind is forecast to be from the NE at just 6 mph, leaving it glassy. For a sandbar break that's fairly exposed to the swell, that's about as good as it gets. The water temp is sitting at 75°, which is 5° warmer than normal for this time of year – very unusual, so you can leave the thick wetsuit at home. Just be aware that crowds are often an issue here.
Before that, we get a little teaser on Thursday the 20th of August. The morning session will see a nice 4 ft NW groundswell with a very long 11-second period, and it'll be clean with glassy conditions and light WNW winds. The combined energy is moderate at 273, so not a powerhouse, but it'll be rideable. However, the wind swings around in the afternoon and messes it up. A couple of mornings later, on Saturday the 23rd, there are some small, surfable waves but with light rain around, so it’s nothing to get too excited about.
After that, it's mostly poor surf conditions straight through to the end of August. There's a bit of a pulse showing on Sunday the 30th with a 4 ft swell and glassy morning winds, but the conditions are just average.
So, to be clear, the first week is a write-off for anything good. The Thursday the 20th morning is a brief, clean window if you're desperate. But the real winner, the one with the best combination of size, clean conditions, and energy, is that Tuesday the 1st of September session. It's a promising call this far out, but the near-term forecast has it looking solid. Surf it while you can, because the rest of the second week looks a bit iffy.
Rusty.
