The Lowdown

G'day, Rusty here. Alright, let's have a look at what's cooking for the stretch ahead. We've got a solid window of surf coming our way, but we've gotta be patient for the really good stuff.

The water's sitting at about 67°, which is pretty much what you'd expect for this time of year, so nothing unusual there.

We kick off Thursday the 20th and Friday the 21st, but honestly, it's pretty ordinary. Thursday morning has some knee-high waves with a messy cross-onshore wind, and Friday morning cleans up a bit with a light offshore breeze but the swell is still just small and weak. The real action starts to build from Saturday the 22nd. Saturday morning sees the swell push up to 8ft from the south, with clean conditions and a gentle breeze. It's a good size for experienced surfers, but the energy is ramping up (1797). Saturday afternoon drops back a touch but stays clean.

Now, Sunday the 23rd morning is where I'd be pointing the car. We've got 6ft of south swell with a 12-second period, the wind is light and cross-offshore, and the wave energy is strong (918). It's clean, consistent, and the crowd factor is "sometimes," so you might have a few mates out but it won't be a circus. This is the standout of the first week.

Monday the 24th morning throws a massive 10ft south swell with a very long 16-second period (3817 energy). That's expert territory, and honestly, it's predicted to be too big for this break. If you're a seasoned charger, it's on, but for most of us, it's a day to watch or find a protected reef.

The end of the first week and into the second week, the wind turns nasty. From Tuesday the 25th through to Sunday the 30th, we're looking at a lot of cross-onshore and choppy conditions, with the swell dropping off. Monday the 31st sees a bit of a rebuild with a clean 5ft swell, but it's a short-period windswell.

Looking further ahead, there's a big spike on Friday the 4th of September. Another 10ft south swell rolls in, but with a strong onshore wind. Again, too big and messy for this spot. The best bet in the long range is probably the glassy, small waves on Thursday the 3rd of September.

So, if you're picking your window, Sunday the 23rd morning is the clear winner. Clean, solid, and a good long-period groundswell. For the rest, it's a mixed bag of too much wind or too much size.

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.
