The Lowdown

Alright, this is Rusty, and here’s how the next couple of weeks are shaping up at Barrinha.

We’ve got a bit of a slow start to get through, but once the surf wakes up around the end of the week, it’s looking like there are a couple of absolute crackers on the horizon.

The first few days are flat or just plain messy. Tuesday the 18th is a write-off with a weak, short-period 3ft north windswell and a cross-shore wind making a mess of things. Wednesday the 19th drops right off to nothing. Thursday the 20th is a no-go with choppy onshore winds. Friday the 21st stays tiny but we finally see a clean offshore breeze kick in by the afternoon, even if the swell is still small and weak.

Things start to get interesting on Saturday the 22nd. Morning sees a clean 6ft south swell with light cross-off winds, and the energy is building into the moderate range (517). By the afternoon it’s holding at 6ft, still clean. That’s a solid session.

But the real standout is Sunday the 23rd. The morning brings in a beautiful 5ft south groundswell with a 10-second period. The wind is a light cross-off, almost nothing, making for glassy conditions. The combined energy is sitting at a strong 670. That is a quality window for an intermediate. By the afternoon the swell bumps up to 6ft with an 11-second period and the energy jumps to 1413, which is strong, though the wind picks up to a moderate breeze. The morning is your pick.

Monday the 24th is the big one for the experienced crew. The morning session sees a powerful 8ft south swell with a 13-second period. That long-period groundswell will be packing a punch. Energy is enormous at 2507. The wind is a light cross-off so it will be clean. This is excellent surf, but at over 8ft, it’s strictly for experts. The afternoon holds similar size but a cross-shore wind creeps in and adds a little texture.

From Tuesday the 25th through to the end of the month, it gets a bit messy again with choppy onshore winds and dropping swell. There’s a lull here for several days with nothing worth paddling out for.

Jumping into September, Tuesday the 1st is another one to watch. The morning shows an 8ft south-southeast swell, but it’s a short-period 9 seconds, and energy is moderate-strong at 947. The wind is clean offshore. The afternoon is the real gem though – 8ft from the southeast, a bit of a shorter period at 8 seconds, but clean offshore wind with very good conditions expected. Energy is still strong at 682.

Wednesday the 2nd finishes the run on a nice note. The afternoon goes glassy with a 6ft east-southeast swell. The wind is dead calm, glassy conditions. The energy is moderate at 479. A clean, smaller session to close out the forecast.

So, to sum it up: if you’re an intermediate, your best bet is the morning of Sunday the 23rd. If you’re an expert looking for power, the morning of Monday the 24th is the one to circle. And for a more recent option, the afternoon of Tuesday the 1st of September is looking very clean and fun.

This is Rusty, signing off.

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.
