The Lowdown
Alright folks, Rusty here. Let’s get into it.
Overall, we’ve got a bit of a mixed bag shaping up for the next couple of weeks. The first few days will be a bit messy with onshore winds, but there’s a solid window of clean surf coming in around the middle of the month, and then a serious pulse of southwest swell towards the end of the third week. The real standout is the morning of Saturday the 22nd, with a beautiful glassy session on the cards. Another one to keep an eye on is the big swell arriving on Sunday the 23rd, but that’s only for the experienced crew.
Barrinha is the only spot on the cards, and it’s a fairly exposed beach break that handles south and southeast swell. The water temperature is sitting at 66°F, which is a tick above average for the time of year, but nothing out of the ordinary.
The first recommendation doesn’t come until Thursday the 13th. The morning of the 13th will see a solid 7ft S swell with a 14-second period, and the wind is swinging cross-off from the SW at just 3 mph. That’s clean, lined-up surf for experienced surfers. The combined energy is strong at 1576, so you’ll feel the power. The afternoon holds similar 7ft S swell with a 13-second period and light cross-off winds, also clean. Thursday is the pick of the first week.
Friday the 14th is a step down. The morning sees 6ft SSE swell, but the wind is cross-on from the east at 6 mph, making it a bit bumpy. The afternoon turns into a full onshore blow from the east, which won’t be pretty. Saturday the 15th is also poor – the morning is small and cross-on, and the afternoon turns into a messy 7ft E swell with a short 8-second period and moderate cross-on winds. Avoid that.
Sunday the 16th through to Wednesday the 19th is a real dead zone. Swell drops right off, with tiny waves and persistent cross-on winds. The combined energy is mostly in the double digits, there’s just nothing to get excited about. Thursday the 20th and Friday the 21st are also poor, with lumpy, short-period windswell and strong onshore winds.
Now, here’s the good stuff. Saturday the 22nd morning is a beauty. The swell is 6ft from the SSW with a 10-second period, but the wind is glassy – just 3 mph from the NNE. That means clean, smooth conditions. The combined energy is moderate at 947. This is the one to circle. The afternoon on the 22nd turns into a 7ft onshore mess, so get out early.
Sunday the 23rd morning is a beast. The forecast shows a 10ft swell from the south with a 12-second period, and the combined energy is massive at 4809. This is expert-only territory; the wave size is too big for most. The cross-on wind will make it a bit lumpy, but for the very experienced, there will be some serious power.
Monday the 24th and Tuesday the 25th still have decent size, with 7ft to 8ft S swell, but the winds are a mix of cross-on and cross-off, so the quality will be varied. Wednesday the 26th morning looks promising again with a 5ft S swell and clean cross-off winds from the south at 9 mph. The energy is moderate at 776.
Thursday the 27th is back to small, choppy conditions as the swell fades. All in all, the best bets are the morning of the 13th and the glassy morning of the 22nd.
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.
