The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at our local sandbar. It’s gonna be a tale of two halves, so grab a coffee.

Right off the bat, we’re looking at a bit of a flat start. Thursday and Friday are pretty much write-offs with messy, onshore winds and weak little waves that just aren't worth the paddle. You’re better off waxing your boards for later.

The first real glimmer of hope shows up on Saturday, the 5th. It’s not going to be epic by any stretch, but the morning will offer some small, knee-high waves at around 4 ft from the S. The wind is light and clean though, so it’s surfable. The afternoon is actually better: same S swell bumps up to 4 ft and the conditions clean right up. The combined energy is decent at (475). It’s a gentle start, but it’s a start.

Now, Sunday the 6th is where it gets a bit more interesting, though a little tricky. The morning has some clean 5 ft S/SSW swell (311 energy), but the 8-second period is a bit short and junky. The afternoon jumps up to a solid 8 ft from the S (908 energy). That’s a fair bit of water moving, but still a bit on the raw side with a moderate breeze. It’s a big step up in size.

The standout window, the one you’ve been hanging out for, is Monday the 7th. We’ve got a proper pulse of swell. The morning is the pick of the whole forecast: a clean 7 ft S swell with a light offshore breeze. It’s going to be glassy and lined up, and the energy is pumping at (1103). That’s a solid, powerful groundswell. The afternoon is also big at 8 ft, but the wind swings a little cross-off. Still, Monday morning at Barrinha is the day to clear your schedule.

After Monday, things get a bit messy early next week with onshore winds and some poor conditions. The swell hangs around but the quality drops off hard until…

We get a nice little reset on Sunday the 13th. The morning offers a clean, offshore 4 ft S swell with a lovely 12-second period (457 energy). The afternoon gets even better: 3 ft from the S but with a very long 15-second period (563 energy). That’s a proper long-range groundswell that’ll push through with heaps of power and shape. The wind is light or even offshore. This is another solid session, especially if you like a cleaner, more lined-up wave.

A bit of a wildcard shows up on Monday the 14th. The morning is messy, but the afternoon goes dead glassy. That 4 ft S swell with a 13-second period (590 energy) will be looking smooth as silk. Get in the water if the tide works.

The final week is a bit of a mixed bag of smaller, clean mornings and some onshore afternoons. The standout there is Wednesday the 16th morning. We’re talking a completely glassy 5 ft from the S (509 energy). It’s going to be clean and peeling. That counts as a solid option.

So, to wrap it up: Monday the 7th morning is your absolute best shot for size, power, and clean conditions. If you miss that, the glassy afternoons on the 14th and 16th are the smart, quieter picks. The long-period groundswell on the 13th is also a very tidy session.

Stay safe out there, and don't be afraid of the dawn patrol.

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.
