The Lowdown

Alright folks, Rusty here. Let’s have a look at the swell window for the next couple of weeks.

Honestly, it’s a bit of a slow start. The first week or so is pretty grim, with onshore winds and tiny, weak swell making it hardly worth paddling out. The real standout window is a long way off, but it’s a beauty. The best surf of the whole forecast is on Monday the 10th of August, with a solid pulse of swell. Tuesday the 11th also looks good but the wind might be a bit tricky. Before that, there’s a brief window of clean conditions on Tuesday the 4th of August, but it’s small.

Let’s run through it.

Right now, nothing’s happening. The first few days are a write-off, with cross-onshore winds and any swell that’s around is messy and weak. The water temp is sitting right on average for this time of year at 66°F, so no surprises there.

We finally get a bit of a breather on Tuesday morning, 4th August. It’s not big, but it’s glassy. The swell is from the S at 3ft with an 11-second period, which gives it a bit of push. The combined energy is moderate (275). The wind is glassy, which is a massive plus. This is your go-out for a clean, chill session, but temper your expectations on size.

Then it goes quiet again until Monday the 10th of August. This is the one. The morning brings a strong S swell jumping to 7ft, with a 13-second period (groundswell). The combined energy is a whopping 1446 – that’s strong. And the wind? Clean offshore from the WSW at just 6 mph. This is excellent surf for experienced surfers. The size (over 8ft) makes it a paddle-out for the crew who know what they’re doing. The long period means it’ll have good shape and power, but it might be a bit straight for the beach breaks, so take that into account.

Tuesday the 11th of August morning is also glassy again, with a cleaner 4ft S swell (462 combined energy). The afternoon picks up a longer period (14 seconds) but the wind swings cross-on, so it’s not as clean. The Monday morning is the clear winner.

The rest of the forecast is a mix of small, weak, or choppy conditions. There’s a big gap of poor surf from the 5th through to the 9th, and then again after the 11th. But for that one Monday morning, it’s going to be worth the wait.

There’s no escaping the crowds at Barrinha – it’s a fairly exposed spot that’s very consistent, so when it’s good, you’ll have company. Don’t expect to have it to yourself.

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.
