Las Machas Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s shaping up at Las Machas.

Look, I’m gonna be straight with you. The next 16 days are a bit of a grind. We’ve got some decent swell on the way, but it never quite lines up perfectly. The water temp is sitting about average for the time of year, so no surprises there.

The best window looks like it kicks off Wednesday, September 4th and runs through the weekend. A solid, long-period groundswell from the SW rolls in. The energy builds to a moderate 1136 by Friday morning, with a 4ft swell. The problem is, the wind is light onshore the whole time. It’s not a howling mess, just a light breeze from the SW, keeping the surface a bit lumpy. It’s clean enough for a wave, but not glassy. The swell peaks on Friday afternoon with 5ft and a period of 15 seconds, getting solid but still with that light onshore. This is the only real standout period, but it’s not a classic.

Saturday the 7th sees the swell dropping a touch, 5ft in the morning, and the wind swings cross-onshore in the afternoon, making it a bit bumpy. Sunday the 8th is smaller, down to 2ft, but that 20-second period is a long one. This kind of groundswell can be a bit tricky at a sandbar like Las Machas, as it can break too straight. It’ll be a long wait between sets.

After that, it’s a long, slow fade. From Monday the 9th through to the 17th, the swell hovers between 2ft and 4ft, with that light onshore wind never really letting up. The energy drops from moderate back to weak, with values like 375 or 448. The direction shifts a bit from SW to SSW, but the period drops, so the waves lose their punch. It’s a poor run of surf, and honestly, the last week looks like a write-off. There’s a gap of several days from the 10th onward where I wouldn’t bother paddling out.

This is a spot that’s very consistent, so it’s a bit of a bummer to see such a drawn-out flat spell. The forecasts can change, so don’t write it off completely, but for now, I’d say the only real bet is that Friday the 6th window. It’s not a standout by any means, but it’s the best of a bad lot.

Rusty.
