The Lowdown
Alright, Rusty here. Let's chew the fat on what Prainha’s got cooking.
We’re looking at a bit of a flat start, but one morning is shaping up to be a ripper if the charts play ball.
Right off the bat, Thursday morning, July 23rd, it's tiny and pretty average. We’re looking at 3ft of weak, short-period ENE windswell. Combined wave energy is only 181. Water temp is around 64°, which is just a hair cooler than normal. The wind is dead glassy though, so you can get wet but it’s nothing to write home about.
Now, Friday morning, July 24th, that’s the one to get excited about. We’ve got a solid 6ft of swell pushing in from the SSE. The combined wave energy is a strong 891. The wind is a clean cross-off. This is the big day. It’s a proper, powerful set-up. That size is going to be a beast for any beginner, but if you’re solid on your feet, this is your session.
After Friday, it all goes quiet again. Saturday the 25th is still okay, 5ft of SE swell with 397 energy and glassy conditions in the morning. Then a long, boring stretch sets in.
From Sunday the 26th all the way through to Saturday, August 1st, it’s a big old flat spell. Lots of days with tiny 2ft to 3ft waves and weak energy readings. The winds are all over the place but nothing is making any decent waves. There’s a tiny blip on Saturday afternoon, August 1st, with 4ft of ENE swell, but it’s short-period and weak.
The start of the second week offers a nice rebound. Sunday, August 2nd is a solid day. We’ve got a consistent 4ft of ENE swell with 236 energy and a clean cross-off wind all day. It’s not big, but it’s clean, consistent, and fun. A good, honest session.
Monday morning, August 3rd, also looks interesting. Small at 3ft, but that swell is from the south with a long 10-second period and a combined energy of 261. Glassy wind on top of that long period means the waves should have some nice shape and push for their size.
To be honest, when it comes to the best on offer, you have to look at Friday morning, July 24th. That 6ft of SSE groundswell with clean offshore wind is the clear standout in this 16-day window. All the other days are just trying to compete with that one.
Prainha can get some company, especially on a day like that Friday, so plan for it.

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.
