The Lowdown

Alright, let’s talk about what’s going on at Barrinha. This is a fairly exposed spot that can handle a bit of swell, and it’s very consistent, so you know there’s almost always something to look at. Over the next couple of weeks, we’ve got a bit of a mixed bag — some decent windows, but also some long gaps where you’ll want to leave the board at home.

The water is around 66°, which is about average for this time of year — nothing unusual.

The first real chance to get out comes on Tuesday morning, September 1st. The swell is 5 ft from the ESE with a short 8-second period, but the wind is cross-off from the SW, keeping things clean. The combined energy is moderate (317). It’s not pumping, but it’s surfable. The afternoon sees a bit more size at 6 ft from the SE, still cross-off, but with a risk of thunderstorms — keep an eye on the sky.

Wednesday morning, September 2nd, is where things clean up nicely. Offshore wind from the SW at 6 mph, swell 6 ft from the SE, period 9 seconds, and combined energy of 450 — that’s moderate energy. The face should be clean and lined up. This is your best window in the first week, no question.

Then we hit a dry spell. From Wednesday afternoon all the way through to Monday morning, September 7th, there’s really nothing worth paddling out for. It’s a stretch of small, weak, or choppy conditions. The morning of the 7th has 5 ft from the S, cross-off wind, but it’s still marginal — energy is 339, but the quality just isn’t there.

The next highlight comes late in the outlook. Tuesday morning, September 15th, is a standout. The wind goes glassy — zero wind from the NW — and the swell is 6 ft from the SE with a 12-second period, which is a proper groundswell. Combined energy is a strong 1128. This is a powerful, clean setup. The longer period will really push through at Barrinha, and with the glassy conditions, the waves will be well-shaped and consistent. Just be aware that with size over 5 ft, this is better suited to intermediate surfers and above.

Tuesday afternoon holds decent at 5 ft from the SE, cross-off wind, energy 668, but it’s a step down from the morning session.

So bottom line: Wednesday morning, September 2nd, and Tuesday morning, September 15th, are your best bets. The 15th especially looks promising — glassy, solid swell, and that long period — but it’s further out, so keep an eye on the forecast as it gets closer.

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.
