The Lowdown

Alright, Rusty here. Let's get into it. The first few days are pretty ordinary, but we've got a couple of proper sessions shaping up that are worth pointing the car at.

It kicks off with a bit of a fizzle. Thursday afternoon through Friday is all small and messy, not worth paddling out for. You're dealing with weak, cross-onshore slop that's barely moving. Better to wait.

Then Saturday 22nd morning, things turn around sharpish. Praia da Baleia is a beach and point setup exposed to the south, and we've got a clean 6ft S groundswell rolling in with a solid 11-second period. The best part? Glassy conditions, not a breath of wind. That's a proper dawny right there. The combined swell energy is kicking at 660 (moderate energy), and the water is a touch warmer than normal for late August. Crowds can pop up here sometimes, but with conditions that clean, it’ll be worth sharing the lineup.

The standout window, though, is from Monday 24th into Tuesday 25th. Monday afternoon sees the swell pumping up to 8ft from the south with a long 14-second period. That’s a lot of water moving. The combined energy hits 2524 (strong), so expect proper power. This is skilled surfer territory—over 8ft means it’s for the experienced crew. But the real gem is Tuesday 25th morning: a glassy 7ft S swell, 14-second period, and offshore winds. Excellent conditions for those who know what they’re doing. The water temperature anomaly is about average for this time of year, so nothing unusual there.

Wednesday 26th morning holds onto that quality with a clean 6ft S groundswell, the period stretching out to a very long 16 seconds. That kind of period can make beach breaks a bit straight, but at a point setup like Baleia, it’s going to run and offer up some proper lines. Combined energy is 1776 (strong), and the glassy wind is a massive plus. This is also only for solid surfers.

After that, things wind down. From Thursday 27th onward, the size drops and the wind starts to mess with the shape a bit. There’s a small window on Saturday 29th morning with a cross-off breeze cleaning up a 4ft E swell, but it’s nothing that’ll get the heart racing. The last real pulse of interest is on Thursday morning, September 3rd—a glassy 7ft S groundswell with a very long 16-second period, putting the combined energy at 1963. That’s a full two weeks out, so call it a promising long-range prospect rather than a sure thing, but it looks like a late-season gem if it holds.

So, to sum it up: the pick of the bunch is Tuesday 25th morning for the expert crew, with Saturday 22nd morning as a solid warm-up for everyone else.

Rusty, out.
