The Lowdown

Alright, let’s look at what’s coming up for the next couple of weeks.

First few days are nothing special. Saturday the 12th brings a 6ft south swell, but wind is cross-off at 16 mph and the period is a short 7 seconds. Water temp is 62°F, which is 4°F colder than average – that’s pretty chilly. Combined wave energy is moderate at 333. Waves are poor for surfing. Skip it.

Sunday the 13th and Monday the 14th are small and clean but weak. Monday morning has a 4ft south swell with a nice 11-second period and light offshore wind. Energy is 361 – moderate. It’s clean but small.

The first real standout is Wednesday morning, the 16th. We’ve got 7ft of south swell, 8-second period, and strong energy of 1078. Wind is light cross-off from the southwest at 9 mph. This is punchy and powerful – very good conditions. Barrinha is the spot to be. At 7ft, it’s for intermediate to experienced surfers only. Crowds can show up sometimes.

Then things go downhill. From Thursday the 17th through the 22nd, the wind turns cross-on or onshore most of the time. There’s size – 5ft to 6ft – but it’s choppy and messy. Not worth the paddle.

There’s a gap of several days with no real recommendation, until Thursday the 24th. That morning is the absolute standout of the whole outlook. Swell is 6ft from the south, 10-second period, and the wind is glassy – just 3 mph from the north. Combined energy is massive at 1594 – very strong. This is excellent for experienced surfers: clean, powerful, and lined up. That’s the morning to circle.

Friday the 25th and Saturday the 26th still have size (5ft–6ft) and long periods (12–13 seconds), but the cross-on wind messes with the surface. Still, if you’re keen, you might find something.

Bottom line: Thursday the 24th morning is the best of the whole run. Glassy and solid.

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.
