The Lowdown

Alright, this is Rusty comin' at ya with the long-range look for our local spot.

Alright folks, it's a bit of a mixed bag we've got on the horizon. There's a real slow start, with nothing worth paddling out for over the first few days. But don't you worry, because the back half of the forecast period has some serious potential, especially for the more experienced among you. The water is sitting at a chilly 65°, which is a full 4° colder than normal for this time of year, so you'll want a good 4/3 wetsuit if you're heading out.

The first real glimmer of hope comes on Saturday, September 19th. The early morning is shaping up to be a proper standout. We've got a solid 6ft groundswell from the NW, and get this – the wind is light offshore from the east. That combo is going to groom Praia das Macas into something special. The wave energy is pumping hard, with a reading of 1623, and the sets will have some real power behind them. But I gotta be straight with you, this is an exposed break and with the swell over 5ft, it's gonna be too much for beginners. This one is strictly for the experienced crew. Expect some crowds too, as it's a known spot.

Saturday afternoon sees the wind shift, turning cross-onshore and making things a bit messy. The quality drops right off.

Next up, Sunday morning, September 20th is another very good option. The swell eases a touch to 5ft from the NW, but it's still holding good energy (655). The wind is offshore again from the southeast, which will keep the waves clean and lined up. Another solid session for the confident surfer.

Moving into the next week, Monday morning, September 21st looks excellent again. A long-period 5ft NW swell (14 seconds) rolls in with a light cross-offshore breeze. The energy is still strong at 1047. This is a classic setup for some proper, powerful walls.

Then we hit Tuesday morning, September 22nd. The wind is forecast to be dead glassy from the southeast. Glassy! That's a major positive. There's a clean 5ft NW swell (878 energy) coming in. It doesn't get much better for clean conditions.

The swell starts to fade after that, but Wednesday morning, September 23rd offers a fun, smaller session with 3ft waves and glassy conditions. After that, we're looking at a long stretch of small, wind-affected slop right through to the end of the forecast period. A few marginal days pop up around the 26th and 27th, but nothing that's gonna get the heart racing.

So, to wrap it up: the first half of this run is a write-off. Your best bets are the mornings of Saturday the 19th, Sunday the 20th, Monday the 21st, and Tuesday the 22nd. Those are your windows for the best quality surf on offer.

Rusty.
