The Lowdown

Alright folks, Rusty here. Let's have a look at what Prainha has in store for us over the next couple of weeks.

It's a bit of a slow start, but there's some real promise if you're patient. The first solid option doesn't show up until the morning of Saturday, August 29th. That's a few days of waiting, but it might be worth it.

That Saturday morning, the swell is a clean 5.6 ft from the ENE, but with a short period of 8 seconds, so it's gonna be a bit fat and crumbly. The wind is glassy though, absolutely dead calm (3 mph from the WSW), which is a major positive – it’ll be clean as a whistle. The wave energy is moderate at best (360).

Sunday the 30th morning sees the swell drop a bit to 3.9 ft from the same ENE direction, but we get a light cross-offshore breeze from the south at 6 mph, making for some clean, lined-up walls. Not huge, but fun.

Then we hit the first real standout. Monday, August 31st morning. The swell bumps back up to 5.6 ft from the east, with a slightly longer 9-second period. The wind is light from the west at 3 mph, giving us a nice cross-offshore flow. Combined wave energy is moderate (474), and the conditions are clean. This is your best bet for the first week, a proper little morning session.

Hold on to your board for the next one. Wednesday, September 2nd morning is the highlight of the entire forecast. We've got a solid 7.2 ft groundswell from the SSE with a long 11-second period. That's some proper energy, and the combined swell energy is strong (1279). The wind is glassy again – 3 mph from the south. This is excellent surf for experienced surfers; it'll have some punch and the offshore wind will make for some beautiful, hollow walls. This is the one to circle on the calendar.

The quality holds up for the morning of Thursday, September 3rd, with 5.6 ft from the SSE and a clean cross-offshore breeze, but it's not quite as strong as Wednesday.

After that, it gets pretty average for a few days, with some poor wind and weaker swell. Keep an eye on the morning of Sunday, September 6th – a 5.6 ft ENE swell with a clean cross-offshore breeze, but the period is a weak 6 seconds.

The next real standout is a bit of a long-range call, so don't book the flight just yet. Friday, September 11th morning looks very promising. We've got a 5.2 ft swell from the SSE with a nice long 12-second period and glassy conditions. That same afternoon looks even more interesting for the experienced crew, with a smaller 3.6 ft swell but a very long 15-second period from the SE, blowing a light cross-offshore. The combined energy is very strong (1309), and it’s rated as excellent. That's a long-period groundswell, so at Prainha, being a beach break, it might be a bit straight, but the quality should be there for those who can handle the power.

Stay stoked.

Information about the Prainha Surf forecast

The above surf forecast table for Prainha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Prainha can be found by selecting the local surf guide option on the grey menu. Our Prainha 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 (Prainha) 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 Prainha 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.

Prainha is 17 km (11 miles) from the city of Tijucas. If you plan a holiday in Santa Catarina - Norte, look for hotels and other accommodation in Tijucas. Tijucas has rooms for a wide range of budgets as well as car hire and transport links.
