The Lowdown
Alright, Rusty here. Let's break it down.
Looking at the long-range for Barrinha, we’ve got a slow start with a lot of choppy, onshore junk. But if you’re patient, there are some solid windows opening up, especially as we roll into September.
The water temp is about 66°, right on the money for this time of year.
The first real chance of a wave comes on Monday, the 31st of August. A 8ft swell from the ESE, but with a short period of 7 seconds, so it'll be a bit jumbled. The wind is light offshore from the WSW, cleaning it right up. The combined energy is moderate (455). For Barrinha, a clean 8ft with offshore wind will offer some fun, punchy rides, but that short period means it won't be the cleanest of lines. Still, it's your best bet in the early going.
Tuesday, the 1st of September, keeps it going with a 4ft SE swell, again with light offshore wind in the morning. A solid follow-up, moderate energy (268). Nothing to write home about.
Now, here comes the big one. Wednesday, the 2nd of September. A massive 13ft SSE swell shows up with a 10-second period. This is a huge amount of water, strong to very strong wave energy (2908). The wind is offshore from the SW, so the faces should be clean. But at 13ft at Barrinha, this is a beast. It's for experts only, full stop. Beginners need to stay well clear. That's your standout big-wave day, but it comes with a major warning.
After that peak, it settles down. The 3rd and 4th of September offer some cleaner, more manageable surf in the 6ft to 5ft range. Crowds can sometimes be a factor at Barrinha, so keep that in mind.
Looking further out, Monday, the 7th of September, is a real gem. A 5ft S swell, but with a long period of 13 seconds, making it a proper groundswell. The wind is glassy from the NE. This is your second standout. The combination of a clean groundswell and glassy conditions will produce some beautiful, lined-up waves for everyone from intermediates up. The energy is moderate (894).
So, there you have it. A lot of waiting for the first week. The standout for the big dogs is Wednesday, the 2nd of September. For a more classic, quality session, lock in Monday, the 7th of September.
Rusty out.

Information about the Barrinha Surf forecast
The above surf forecast table for Barrinha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barrinha can be found by selecting the local surf guide option on the grey menu. Our Barrinha 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 (Barrinha) 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 Barrinha 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.
Barrinha is 17 km (11 miles) from Imbituba. If you plan a holiday in Santa Catarina - Sul, look for hotels and other accommodation in Imbituba. Imbituba has rooms for a wide range of budgets as well as car hire and transport links.
