The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it’s a tough stretch ahead for Praia do Norte. The whole 16-day window is looking pretty grim, with no real standouts to get excited about. The wind is just not playing ball, and it's either cross or cross-onshore for most of the run, which is gonna leave things choppy and messy.
Right from the start on Sunday, August 2nd, we’ve got a weak 2ft W swell wrapping in with a 10-second period. The combined energy is only 120, which is weak, and with a cross-on NW breeze at 9 mph, it’s just not worth paddling out. The water’s sitting at 68°, which is about average for this time of year, but that’s the only thing that’s normal.
We slide through Monday and Tuesday with tiny, poor-quality 2ft to 3ft swells, and the wind stays on it or cross-shore. The energy picks up a bit by Thursday the 6th, with a 5ft NNW swell and a moderate 469 energy reading, but it’s straight up ruined by a fresh N cross-breeze at 19 mph. Friday the 7th and Saturday the 8th are the same story – chest-high lumps but with that nasty cross-chop.
The pattern doesn’t let up. We go through the whole first week and into the second with the same story: moderate-sized swell (5ft to 6ft) but always with that cross or cross-on wind. The period stays short, mostly 7 to 9 seconds, so there’s no real power or shape to the waves. It’s just wind-affected junk.
The only thing that might make you look twice is the morning of Saturday the 15th. We’ve got a 7ft NNW swell with an 8-second period, and a solid 547 energy reading. The wind finally swings onshore from the WSW at 9 mph, but it’s still only a marginal call. It’s not proper, and it’s definitely not for beginners – that’s big, lumpy, and likely closing out.
Then Monday the 17th morning, the pulse gets bigger: 10ft to 12ft NNW swell with a 9-second period, and the energy goes through the roof at 1337 to 1648. That’s a serious amount of water moving. But the wind is still a factor, going from cross to cross-on. That’s expert-only territory, and even then, with the short period and onshore wind, it’s going to be a messy, dangerous beast. This is more of a kite-surfing show than a paddle-surfing session.
Sorry, crew. This is one of those blank runs where the forecast just isn’t giving us anything clean. Don’t hold your breath.
Rusty.
