The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got coming for this stretch of coast.
Right off the bat, the next week or so is a tough one. For a spot as open as Praia do Norte, the wind is gonna be our worst enemy for a while. We’re looking at a big gap with no real surf recommendations until we hit Friday the 28th of August, so that’s about four days of just watching the wind howl.
The standout window is shaping up for Friday the 28th of August. That morning, you’re looking at a solid 10ft swell from the NW with a 12-second period. That’s proper groundswell energy, and the combined energy is a hefty 2824 – that’s strong stuff. The wind is a cross-onshore from the NNW at 9 mph, which isn’t perfect, but it’s manageable for the crew who know this wave. This size is pushing into expert territory, so if you’re not confident in the big stuff, give it a miss. The long period means the sets will be a bit slower, giving you time to paddle out, but at a beach-and-reef setup like this, those long-period swells can pitch up and jack. It’s going to be a wild, raw day. Expect crowds, this spot gets busy when it’s on. The water temp is about average for the time of year.
The Saturday the 5th of September is another one to circle. That afternoon, we’re talking a massive 12ft swell from the NNW, period of 9 seconds, and the combined energy is a beastly 2547. Again, this is strictly for the experts only – well over 8ft. The wind is a moderate cross-shore at 16 mph, so it’ll be lumpy and challenging. The shorter period means the waves will be a bit more jumbled, but there’ll be plenty of grunt.
Beyond that, from the 6th into the 8th of September, the swell drops right back to around 4ft, but the period gets very long – up to 18 seconds. That’s a very long-period groundswell from the WNW. The energy is still moderate (around 1163 to 1899), but with that kind of period, the waves will be very clean and lined up, but they can be tricky at a beach break, closing out. The cross-shore wind is better, so it could be a sneaky little window for a longboard or a step-up, but it’s not the highlight.
So, to wrap it up: this is a tale of two weeks. The first half is a write-off with dirty wind. The real action is on Friday the 28th of August for the big-wave hunters, and again on Saturday the 5th of September for those who want a massive, challenging paddle. The rest is either too small or too wind-affected.
Stay safe out there.
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.
