The Lowdown
Alright, surfers, Rusty here. Let’s break down what Mother Nature has in store for us at Barrinha over the next couple of weeks.
First up, the water temp is sitting at 66°F, which is pretty much spot on for this time of year – nothing unusual there, just your standard late-summer warmth.
The real action kicks off this Friday afternoon, August 14th. We’ve got a solid 8ft SSE groundswell rolling in with a 13-second period, packing a serious punch of energy (1909). The wind is glassy from the ESE at just 3 mph, so the conditions are going to be absolutely pristine. This is premium stuff for experienced surfers only – the size and power will be too much for beginners. This is your standout session of the whole outlook.
After that, things go quiet. Really quiet. We’re looking at a massive gap in quality surf from Saturday, August 15th, all the way through to the morning of Friday, August 21st. During that stretch, the swell drops off, the wind gets messy, and we’re mostly dealing with small, weak, and choppy conditions. Not worth paddling out for.
We start to see a pulse of life again on Saturday morning, August 22nd. A 5ft S swell (10 seconds) with clean, cross-off winds from the SSW at 6 mph. The energy is moderate (505), and while it’s not the Friday standout, it’s a solid window for a session.
The swell really builds into Sunday, August 23rd, with a 10ft S swell (12 seconds) and a massive energy reading (4074). The winds are clean and cross-off, but here’s the catch – that’s too much wave for this break. This is strictly for experts, and even then, it might just be closing out. Same goes for Monday, August 24th, with an 12ft swell (5054 energy) – that’s a beast of an ocean, and it’s going to be overwhelming.
Things settle down nicely by Tuesday morning, August 25th. We’ve got a 6ft S groundswell (12 seconds) with glassy conditions and 1074 energy. This is a much more manageable size, and it’s going to be clean and fun. The afternoons look good too, with a 6ft swell and light cross-off winds. This is probably your second-best bet for the whole period.
Wednesday, August 26th, keeps the trend going with a 4ft to 4ft S swell, clean winds, and a gentle offshore in the morning. Good, solid, everyday surf.
The tail end of the outlook, from the 27th onward, gets a bit messy again with onshore winds and smaller, choppier swells. Not a great way to finish the run.
So, to sum it up: Friday afternoon the 14th is the absolute winner – don’t miss it if you’ve got the skills. Tuesday the 25th is your next best call. The rest of the time is either flat, too big, or too windy.
Stay stoked, and keep an eye on the horizon.

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.
