The Lowdown
Howdy, Rusty here. Let’s talk about Praia do Norte for the next couple of weeks. I’ll level with ya – the outlook is a bit of a bummer for surf. You got a lot of days where the wind and swell just ain’t lining up, and the scores are flat most of the time. Water temp is about normal for the season.
The first day worth paddling out is Saturday morning, the 22nd of August. We got a 5ft swell from the NNW with a 10-second period and moderate energy (484). Wind’s light from the NW at 6 mph but cross-onshore, so it’s a bit bumpy – real marginal. That afternoon gets worse with onshore wind. Sunday morning the 23rd is the only real highlight in the first week. Swell builds to 6ft from the WNW, 11-second period, and energy is solid at 862. Wind is SSE at 12 mph, which is cross-offshore, and the waves clean right up. Those are well-shaped lines on the reef, but at over 5ft, it’s too big for beginners – more for the advanced crew. Crowds are sometimes an issue here.
Then we hit a long, dry spell. From Sunday afternoon the 23rd all the way to the end of August, it’s a bust – onshore winds, chop, lumpy mess, and all zeros on the scores. That’s a gap of over a week with nothing.
Saturday morning the 29th of August brings a bit of a flicker. There’s 6ft swell from the NNW with a long 11-second period, good energy (687). Wind is light from the north at 6 mph, giving light cross-shore conditions – clean enough but still marginal. That afternoon goes choppy again. Then another gap of small, quiet surf.
Later on, Thursday the 3rd of September shows 5ft from the NNW but with a short 6-second period and moderate energy (210), with moderate cross-shore wind – messy. The afternoon gives 6ft, but same short period and cross-onshore chop. Friday the 4th and Saturday the 5th of September see 7ft swells from the NNW, but the wind howls at 22–25 mph from the north, turning it into lumpy, blown-out slop. That’s expert-only height, but truth be told, with that wind and poor quality, it’s more of a kite-surfing setup than a paddle session. This is a lean stretch for the area, but don’t lose hope – the forecasts can change.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Praia do Norte may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
