The Lowdown

Alright, let’s get into it. The surf is gonna have its moments over the next couple of weeks. We’re looking at a solid pulse of south swell to kick things off, but we gotta pick our windows wisely. The water’s sitting at about 67°, which is pretty much normal for this time of year, nothing crazy there.

Barrinha (Start of Forecast) is the main event early on. Monday the 10th is the standout start. It’s got some overhead energy, we’re talking a solid 7ft of south swell with a long 12-second period. The wind is light offshore in the morning, making for some proper clean conditions. The energy is strong at 1706, so there’s plenty of push. This is the best on offer to start the week, but it’s not for the faint-hearted at that size. Tuesday the 11th morning is also a cracker – slightly bigger face at 7ft but glassy winds, just magic. You’ll want to get on it early before the breeze swings around.

Then things get a bit messy for a few days. Wednesday and Thursday are mixed with some cross-onshore winds and rain, dropping the quality. It’s not terrible, but it’s not worth getting wet for unless you’re desperate. By Friday the 14th, the swell is fading and the winds are messy again and it stays pretty average through the weekend. The swell drops out badly, with poor, weak waves and choppy conditions on Saturday and Sunday. It’s a proper lull.

The following week picks back up. Monday the 17th has some small, glassy waves, but it’s pretty weak. The real second pulse comes on Tuesday the 18th, with a bump in size to 8ft from the south. But the period is a short 9 seconds, so it’s going to be a bit less clean, and the winds are more cross-off. Not the quality of the first pulse. There’s another push Wednesday the 19th, but the onshore wind is going to ruin it.

Looking further out past the 20th, there’s a fair bit of wind but not much decent swell. A cleaner window pops up on Friday the 21st with some cross-off breeze and a long 13-second period, but it’s only around 5ft, so it’s a smaller, cleaner day for the longboard or a fun mid-length. After that, it’s a slow fade into small, weak, and mostly onshore mush through the end of the period. It’s a bleak finish, honestly.

So, if you’re picking your battles, Monday the 10th morning and Tuesday the 11th morning are your clear standouts. Bigger, clean, and lined up. The later days are more about managing expectations.

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.
