The Lowdown
Alright, grab your wettie, 'cause I'm gonna walk you through the next couple of weeks at Praia do Norte. This spot is a heavy, advanced-only slab – when it's on, it's world-class, but it demands respect. The water temp is sitting at 66°, which feels a bit colder than what we normally expect for this time of year.
We've got a real slow start here. The first good look doesn't come until Saturday the 19th in the morning. That's a long wait. From the 14th through the 18th, it's a write-off: either howling cross-shore winds or messy, lumpy conditions. The wait is worth it if you've got the skills.
The standout session is hands down the Saturday morning of the 19th. We get a solid 8 ft groundswell out of the NNW with a very long 14-second period. The combined energy is massive (2386), meaning there's a ton of power behind those lines. The wind is offshore from the ENE and light as a feather, keeping the surface glassy and clean. This is big, powerful, perfect-point-reef-type swell. It's strictly for the experienced crew – this will be well overhead and pushing hard.
Sunday morning, the 20th, is another good call. Swell drops to a still-sizable 6 ft from the NNW, period at 12 seconds. Combined energy is moderate at 743. The wind is light and cross-off from the ESE, meaning clean, lined-up waves. It's a step down in size from Saturday but will still be a very, very good session.
Looking further ahead to Friday morning, the 25th of September, we've got another promising window. A new 6 ft swell out of the WNW with a long 14-second period shows up. Combined energy is back up to 1130, so the ocean is working. The morning is glassy with an ESE breeze, setting up some beautiful conditions. This is a promising look but it's a way off, so keep your fingers crossed.
For the more average days, the 21st and 22nd of September mornings offer clean, cross-off conditions with 4 ft swell from the NW, but the energy isn't as impressive as the standouts. By the end of the month, from the 24th onward, it trails off into much smaller swell unless that Friday the 25th window delivers.
Stay sharp, respect the lineup, and don't paddle out if you're not sure.

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. Our Praia do Norte surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Praia do Norte) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
