The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Overall, the pattern starts with some challenging, powerful surf, then settles into a cleaner but smaller window, before a couple of long-range pulses show some promise. The opening days are big and a bit wild, so we’ll need to pick our moments.
Sunday, September 6th kicks off with solid, raw energy. Morning sees 8ft from the south, with a short, weak period of 8 seconds, making for a lumpy, less organised feel. The combined swell energy is moderate at 939, but a 25 km/h cross-off wind from the SSW keeps it rideable and clean for the more experienced. By afternoon, it jumps to 10ft and the energy ramps up to a very strong 1509. The swell period lengthens to 10 seconds, but honestly, at this size, it’s likely too much for most and best left to the experts.
Monday, September 7th is a better shout. The morning drops to a much more manageable 6ft, still solid south swell with a decent 10-second period, giving it some push. The combined energy is a moderate 551. With a light 10 km/h cross-off from the SW, the conditions are clean. This is the standout of the first week. Water temperature is 65°, which is about average for the time of year, so a spring suit is fine.
Thursday, September 10th is another real gem. The swell has dropped to 3ft to 3ft from the south, but the period is a long 12 to 14 seconds, meaning real groundswell lines with good shape and energy between sets. The combined energy is moderate (429–419). The wind goes glassy in the afternoon with a light SE breeze, so you’ll be surfing super clean, lined-up waves. This is the best quality session on offer in the near-term.
We then hit a bit of a lull. From Friday, September 11th through Wednesday, September 16th morning, the surf is mostly small, choppy, or wind-affected, with poor quality. There are some clean moments on the Tuesday, September 15th morning when a 5ft south-southeast swell with a 10-second period and light cross-off wind delivers decent conditions again, but it’s not a major stand-out.
Saturday, September 12th afternoon sees another big pulse of 10ft from the southeast, with a very strong energy reading of 1610. The wind is cross-off from the south, so it could be clean, but this is strictly for experts only. The same goes for the Saturday, September 19th morning, where a 7ft south swell with a very long 15-second period and combined energy of 1830 arrives, but it’s blown out by a 20 km/h cross-on wind.
The very end of the outlook, Monday, September 21st, is flat, with barely any energy (46 and 25), so don’t bother.
For the real standout, I’d be on Barrinha for the Thursday, September 10th afternoon session. Glassy conditions, long-period groundswell (14 seconds), and clean 3ft lines from the south. This is what you wait for. The Monday, September 7th morning is the next best bet for a bit more size with clean conditions. Crowds are sometimes an issue here, so you might have some company on these good days.
Rusty.

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.
