The Lowdown

Alright, Rusty here, let’s break it down.

We’re in a slow zone to start. The first stretch – from the 16th through most of the 22nd – is flat and messy. Tiny waves with choppy onshore wind. A few glassy moments on the 19th, but with waves barely 0.7ft, it’s not enough to get excited about. That’s a solid dead spell.

Things pick up on the 22nd of August. Saturday morning at Barrinha shows a 4ft south swell, 10-second period, with glassy conditions. The combined energy is 237 – moderate. It’s not epic, but it’s the first real sign of life. The afternoon gets bigger at 5ft but picks up a light cross-on breeze – a little bumpy, but surfable.

Sunday the 23rd jumps to 8ft in the morning and 8ft in the afternoon. Both have clean cross-off winds. The energy is strong – 1080 and 1293. That’s expert territory – over 8ft, only for the skilled crew. The swell period is 9 to 11 seconds, so it’s got some grunt.

The real standout? Monday the 24th of August. Morning brings a solid 6ft south swell with an 11-second period and a moderate offshore wind from the southwest. Clean, lined-up waves. Combined energy is 841 – strong. The afternoon drops to 6ft but stays clean with a cross-off breeze. This is the best window. The water temp is about average for late summer.

Tuesday the 25th morning is still good – 5ft, glassy calm, 11-second period – but the afternoon gets trashed by a cross-on wind. After that, it’s a mix. The 27th has clean 6ft waves but with a weak 6-second period – short period, less push. The 28th has 7ft from the ESE, cross-off wind, but the period is 9 seconds – punchy but not as clean.

The end of the month into the 31st goes back to smaller, onshore junk. Your best bet is the 24th. Morning session, offshore wind, solid swell. That’s the one.

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.
