The Lowdown

Alright, Rusty here, let's see what the water's got for us. This forecast is just for this one spot, so I'm not lookin' anywhere else.

Right off the bat, it ain't pretty. We've got a long, quiet spell ahead. The first real whisper of a wave that’s worth paddlin’ out for doesn't show up until Monday the 14th of September. That means the next couple of days are a write-off – don't even bother waxing up.

So, here's the rundown. The pick of the whole 16-day window is gonna be Barrinha on Monday the 14th of September. Both the morning and afternoon sessions are lookin' like the best we're gonna get. The morning brings a clean 4ft swell from the south with a period of 11 seconds – that's some proper groundswell energy, you'll feel it. The combined energy is at 473, so there's a good, solid push behind it. Winds are a gentle offshore from the southwest, keepin' the faces smooth. That's the session to circle on the calendar. The afternoon drops a bit in size to 3ft, but it's still clean with that same offshore wind. The best part? This break is very consistent, so you won't be sittin' around waitin' forever. It does get crowded sometimes, so get in early.

Now, Tuesday the 15th of September is still rideable. The morning has a small 3ft swell from the southeast with clean, gentle offshore winds. Not gonna blow your socks off, but it's clean and rideable on the right board. The combined energy is a weak 187, so it’ll be a little gutless. The water temp is about average for this time of year, nothin' wild to report there.

Then we hit a rough patch. From Wednesday the 16th through to Monday the 21st, conditions get messy. We get a bit of size – up to 6ft on the Wednesday morning – but the winds turn cross-off and then cross-onshore, choppin' it all up. The swell period drops to 8 seconds on the bigger days, so you're lookin' at wind-affected, weak lumps. Not worth the paddle.

There's a flicker of hope on Monday the 21st of September morning with a 6ft easterly swell and 8-second period, and light cross-shore winds, but the forecast says it's marginal. It's a long way out, so keep an eye on it, but don't get your hopes up.

After that, from Tuesday the 22nd onward, it's a total flat spell. Swell sizes drop to 1.0ft and lower, combined energy falls to a pathetic 17 and then to single digits. It’s officially dead. The only thing that breaks the silence is a surge of strong, clean wind on Wednesday the 23rd and Thursday the 24th, but with swell around 5ft to 7ft and short 7-second period, it’s messy and blown out. The Thursday morning the 24th has a big combined energy of 1487 from a 7ft south swell, but it's rated as marginal. With those strong winds and that size, this setup looks more interesting for kite surfing than for a traditional paddle session, honestly.

The very end of the forecast window, Friday the 25th of September morning, shows a glimmer with a 5ft south groundswell at 12 seconds and light winds – combined energy at 556, promising. But again, it's a long way out, so we'll see. After that, it fades back to nothing.

So, to wrap it up: Monday the 14th of September at Barrinha is your one true standout. Get it while you can, because this forecast has a whole lot of nothin' before and after.

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.
