The Lowdown
Alright folks, Rusty here. Let’s get into the outlook for Praia do Norte. This is a big, exposed beach and reef setup that holds a lot of power, and it’s not for the faint of heart. Right now, we’re looking at a pretty frustrating stretch ahead. For the first few days, the wind is just a mess—cross-shore and cross-on all day, wrecking any chance of clean lines. The swell is there, but it’s mangled by the breeze. The real story is a dry spell with no quality surf for the first week, really. The best chance we’ve got is a brief window on Friday, September 11th.
Alright, let’s break it down.
The first solid recommendation doesn’t come until Friday morning, September 11th. We get a brief lift with the conditions. The wind swings NNE at 6 mph, giving us a clean cross-offshore breeze. The swell is a modest 4 ft coming from the NNW with a period of 10 seconds. The combined energy is moderate at 268. It’s not huge, but it’s clean. The water temp is about average for this time of year, so nothing unusual there. For a spot this exposed, this is the one standout—a short, sweet moment of clean surf before the wind screws it up again in the afternoon.
Saturday morning, September 12th, is surfable but very ordinary. The swell drops right off to 2 ft from the NNW with a short period of 7 seconds. The energy is weak at 83. Wind is light NNE at 6 mph and it’s clean again, but the waves are tiny and weak. It’s a beginner-friendly day if you’re desperate, but not one to get excited about.
Then we go into a long, grim run. From Sunday, September 13th, right through to the end of the forecast on September 20th, the conditions are poor. The wind howls from the N and NNW at 12 to 22 mph, bringing a nasty cross-shore chop. The swell picks up a bit, with 6 ft to 8 ft on the Sunday and Monday, but it’s all wind-affected, lumpy, and ugly. The combined energy is moderate to strong (up to 713), but the quality is just not there. For a spot this size, with the wind on it, this is more of a kite-surfing setup than a paddle session. The 8 ft on Sunday the 13th afternoon is definitely expert-only territory if you tried, but the wind will make it a battle.
The final few days, from September 16th onward, the swell fades to 2 ft to 3 ft and the wind stays onshore or cross-onshore. It’s a flat, choppy end to the outlook.
So, bottom line: the only real window for a clean wave is Friday morning, September 11th. That’s your standout. The rest of the 16 days is a write-off for quality surf at Praia do Norte. The forecast can always change, but as it stands, you’re waiting for that one clean morning.
Rusty.
