The Lowdown

Alright, Rusty here. Let's chew the fat on what's coming down the pipe for the next couple weeks. I'll be honest, looking at this forecast is a bit like watching paint dry – there's not a whole lot to get fired up about for a proper surf.

The only game in town is Praia das Macas. The sky's mostly gonna be clear, so you'll at least have a nice view while you're staring at the flat line. Water temp is pretty much what you'd expect for this time of year.

The big problem? The wind. For basically the entire 16-day window, it's gonna be blowing from the side or onshore, often with some serious muscle behind it. That spells chop, lumps, and generally poor surf.

Saturday, September 5th is the one bright spot. The morning session is glassy with a 3ft WNW swell. The energy is moderate (121), but it's a short-period swell. It's surfable, but nothing to write home about. This is really your only shot at clean waves for a long while. After that, the wind cranks up and the quality just tanks.

Thursday, September 10th morning might be less windy, but it's still a marginal call. You'll have a 5ft NW swell with a longer period, but that crossing breeze will still mess with the surface.

We do see some bigger swell later on. Take the morning of Sunday, September 13th – we're talking a 6ft swell, and the afternoon before that hits 8ft. But the wind is gonna tear it to pieces. That Sunday afternoon with 8ft swell and an 18 mph cross-onshore? That's looking more like a kite-surfing playground than a clean surf break. It's gonna be a lumpy, blown-out mess.

So, what’s the call? We've got a long, dry stretch of poor conditions. The one and only standout is that Saturday morning glass-off on the 5th. If you're itching for a paddle, that's your window. After that, I'd say save your energy and hope the forecasts look better down the road.

Rusty.
