The Lowdown

Alright folks, Rusty here. Let’s break down what’s on the cards for the next couple of weeks.

Alright, the first week is a bit of a slow burner, but there’s a clear window of quality surf forming from Sunday the 9th through to Wednesday the 12th. The standout session looks like Sunday afternoon, where it all comes together nicely.

We’re looking at Barrinha first up. The water temp is sitting at 67.1°, which is about normal for this time of year, just a touch warm. You’ll be on a 6.2ft south swell, period of 11 seconds, and with that light rain and clean cross-offshore wind, the wave face is going to be smooth. The combined energy is solid at 1174 (moderate to strong), so there’s plenty of push. This is easily the best session on offer, with a clean, lined-up feel. Crowds are sometimes an issue here, so keep that in mind.

Monday the 10th keeps the quality going through the morning with a clean 5.9ft south swell (12s period, 880 energy) and a light cross-off breeze. The afternoon is similar, with a 6.2ft south swell. Both sessions are clean, but the afternoon has a bit more grunt. Tuesday the 11th is still good, with a clean 6.2ft south swell in the afternoon, though the period drops to 11 seconds. Wednesday the 12th finishes this run with glassy conditions in the morning on a 4.6ft SSE swell (12s, 570 energy) and a glassy afternoon on a 3.9ft SSE swell. It’s all very surfable.

After that, there’s a bit of a lull. Thursday 13th is a write-off, but Friday 14th morning sees a clean 4.6ft S swell (12s, 597 energy) with light offshore wind. That’s a worthwhile dawn patrol. Saturday 15th morning is glassy again on a 5.2ft SE swell (9s, 642 energy), but the period is a touch short. Sunday 16th finishes the week with a clean 3.3ft S swell in the morning and a clean 3.0ft S swell in the afternoon.

Now, looking into the second week, there’s one big, promising but uncertain call. Tuesday the 18th morning has a solid 7.5ft SSW swell (10s, 1637 energy) with a clean cross-offshore breeze. That’s a lot of water moving, and with the period a bit short and the swell size over 6.5ft, this is one for experienced surfers only. The combined energy is strong. It looks promising, but it’s a long way out, so keep your fingers crossed. The following Wednesday morning, the 19th, is a write-off with strong onshore winds, so don’t bother.

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.
