The Lowdown
Alright folks, Rusty here. Let’s get into it. The forecast isn't looking great for the next week and a half, but there is a window that’s got my attention. We’re looking at a long stretch of nothing much, then a solid pulse arrives late in the run.
The first few days are a write-off. From Sunday the 9th all the way through to Saturday the 16th, it’s consistently poor. Cross-shore, cross-onshore winds, choppy conditions, and small, weak swell. The combined energy is mostly in the low to mid hundreds, which is weak to moderate at best, but the wind just tears it apart. You’ll be fighting the chop more than riding the wave. Not worth paddling out.
Things start to change on Monday the 17th. The swell picks up, and the wind finally plays ball. The morning of the 17th is still a bit messy with a cross-shore wind and a 7.2ft swell from the NNW, but the energy jumps to 770 – that’s strong. It’s a bit of a gamble with the tide, but the afternoon is where it’s at. By Monday afternoon, the wind swings cross-offshore from the NNE, and the swell holds at 7.2ft with a 9-second period from the NNW. The energy is still very strong at 714. It’s going to be clean, with proper lines. This is the standout.
Now, Praia do Norte is an advanced, exposed beach and reef setup, and with a 7.2ft swell, this is exclusively for experienced surfers. It’s big, powerful, and demanding. The wind turning cross-off is the key – it’ll clean up those big NNW swells beautifully. The water temp is about average for the time of year, so a good summer wetsuit will do you fine.
Tuesday the 18th sees the swell dropping off quickly, and the cross-shore wind returns, so the window is short.
For the rest of the month, from the 19th to the 24th, it’s back to mediocrity. Small swell, onshore or cross-onshore winds, and choppy surface conditions. The energy drops right down to the low hundreds and even below 100 (74) by the 23rd. It’s a blank run after that Monday pulse.
If you’re an advanced surfer and you’ve been itching for a proper session, the afternoon of Monday the 17th is your only real shot. It’s the one true standout in this 16-day window. Get ready for a big one, but don’t get your hopes up for the rest of it.

Information about the Praia do Norte Surf forecast
The above surf forecast table for Praia do Norte provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Norte can be found by selecting the local surf guide option on the grey menu.

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.
