The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’.

First off, the water is runnin’ a bit colder than usual for this time of year, about 63°F, so you might want a thin spring suit if you’re heading out at Barrinha.

Right now, and for the next few days, we’re in a flat spell. There’s really nothing worth paddling out for. Monday the 20th and Tuesday the 21st are showing tiny, weak waves with poor conditions. The combined energy is barely a whisper (10-44). It’s a bit of a frustrating start, but don’t lose hope.

We start to see a pulse building from Thursday the 23rd. By Thursday afternoon, the swell bumps up to 5ft from the S, with a short period of 8 seconds. The wind is clean, cross-off, and the energy is starting to get interesting (349). It’s still not a standout, but it’s rideable. Friday the 24th brings a bit more shape with the swell shifting to 5ft from the SE, period creeping up to 9 seconds, and glassy conditions in the morning. Combined energy is up to 388. It’s looking okay, but not epic.

Saturday the 25th is a bit mixed. The morning has clean 4ft SE swell, but the afternoon gets a bit messy with a risk of thunderstorms and a bump in energy to 463. Nothing to write home about.

Now, the real standout is Sunday the 26th. This is the one to circle on the calendar. We’ve got a solid 10ft swell from the SSE, with a 10-second period, and the wind is blowing offshore from the SW. The combined energy is a massive 3689—that’s serious power. The morning session looks like it will be firing with clean, offshore conditions. However, this is big. At 10ft, this is strictly for experienced surfers only. Beginners, stay on the beach and watch. The afternoon drops to 8ft with cross-off wind, still good but a step down.

After that, the swell backs off. Monday the 27th still has a clean 6ft from the SE in the morning, but the wind starts to turn onshore later. From Tuesday the 28th onward, it’s a long stretch of poor conditions again. The wind is mostly cross-onshore and choppy, with tiny waves. There’s a little blip on Saturday the 1st of August with a glassy 2ft swell from the SE, but it’s a very long period (14 seconds) which can make it fat and slow at a beach break. The energy is low (134), so it’s just a small, glassy session for a longboard.

The first week of August continues small and mostly onshore. So, the best bet by far is that Sunday the 26th session for the experienced crew. For everyone else, the waits are long, but forecasts can always change.

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.
