The Lowdown
Alright, grab your board, let’s talk about what’s heading our way at Barrinha. Over the next week or so, it’s a bit of a mixed bag with a few windows that’ll have you keen, but you’ll need to pick your moments. The swell energy starts off pretty weak, around 147, and it’s not looking like much, but there is some cleaner surf on the horizon.
Look, the start is pretty average. Wednesday the 5th has tiny 3ft swell from the SSE with a period of 10 seconds. It’s glassy which is nice, but the energy is low (147). It’s surfable but ordinary. Nothing to get excited about.
Things go flat and ugly after that. Thursday the 6th and most of Friday the 7th are a write-off with poor conditions and weak swell. Friday afternoon though, the swell jumps to 7ft from the south with only 8 seconds period, but it’s a cross-offshore wind and the energy spikes to 517. Problem is, it’s marked as poor, so I’d sit that one out.
Saturday the 8th and Sunday the 9th bring a bigger, longer period S swell but winds are messy – cross-onshore on Saturday, cleaner on Sunday. On Sunday morning, we get 7ft S swell with 11 seconds period, energy cranking at 2179. The wind is clean cross-off, but conditions are rated marginal. For the experienced surfers, this might be worth a look, but it’s not perfect. Sunday afternoon is a little smaller at 6ft with still good energy (764) and clean wind.
Now, the standout window. Monday the 10th is your best bet early on. Morning has 5ft S swell at 11 seconds, clean cross-off wind, energy at 613. Afternoon gets even better – same size but the period stretches to 12 seconds, energy up to 681, and it’s described as very good surf conditions. Glassy, clean, and consistent. That’s the session to aim for.
Tuesday the 11th drops off a little, still rideable, but nothing special.
Then, Wednesday the 12th morning is another gem. We get 5ft SSE swell with a 12-second period, glassy winds, and energy at 929. It’s rated very good. That morning session will be clean and fun. The afternoon turns cross-onshore, so get out early.
Thursday the 13th afternoon picks up again – 5ft SSE swell at 11 seconds, glassy winds, energy at 822. That’s another sweet window. And Friday the 14th morning has 6ft SSE swell with a 13-second period, offshore winds, and massive energy (1295). That’ll be the best of the bunch for the more confident surfer – clean, powerful, and long-period lines.
After that, it fades and gets messy again until Tuesday the 18th morning. That day delivers 8ft S swell with a 9-second period, glassy conditions, and energy at 1075. That’s solid, but with 8ft and short period, it’s going to be punchy and heavy – expert territory only.
Barrinha is fairly exposed to the S-SSE swells and is very consistent, so even with the gaps, there’s always something to watch. The water temperature is about average for this time of year, nothing unusual there.
Overall, the best windows are Monday the 10th, Wednesday the 12th morning, and Friday the 14th morning. For the brave, Tuesday the 18th morning offers size but it’s for experts only.
Catch you in the lineup.

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.
