The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for this stretch of coast.
We’re lookin’ at a bit of a slow start, with the real action not hittin’ until Wednesday the 2nd. There’s a decent pulse of swell on the way, but you’ll have to be patient. The first few days are pretty average.
Alright, so Wednesday morning the 2nd is where we get our first proper chance. The swell at Barrinha is gonna be a solid 7ft from the SE, with a period of 10 seconds. That’s a fair bit of energy in the water – moderate to strong stuff with a combined energy reading of 916. The wind is a gentle cross-offshore from the SW, which is gonna keep things clean. This is a solid intermediate wave, and with the size it’s a bit much for beginners. This is a standout for the first week, for sure. The water temp is sittin’ around 66°, which is about average for this time of year, nothin’ unusual there.
The rest of the first week is a bit of a mixed bag. Thursday the 3rd gets messy with a strong cross-onshore wind, and Friday the 4th has tiny waves. Saturday the 5th has a bit of small, ordinary swell but the wind stays clean. Sunday the 6th has a bit of a spike in the afternoon with 7ft from the S, but the period is short at 8 seconds, and the wind is moderate, so it’s a bit messy.
Now, Monday the 7th sees the biggest swell of the run, a chunky 8ft from the SSW with a 9-second period. That’s a lot of energy – a combined energy reading of 1866, which is strong. But the wind is a moderate cross-offshore, and with that size, this is expert territory only. It’s a bit raw and the forecast is only marginal, so it’s one for the experienced crew only.
After that little burst, it settles down again. Tuesday the 8th morning looks really nice with 6ft from the SSE and a gentle cross-off wind. That’s a good one. Then Wednesday the 9th morning is a real beauty – glassy conditions with an ENE wind and 4ft swell from the SSE. That’s a smaller, clean day that’ll be super fun for everyone.
Then we hit a dry spell. From Thursday the 10th through to Saturday the 12th, it’s mostly small, onshore, and messy. There are a few days there where it’s barely worth paddling out.
We get a bit of a resurrection on Sunday the 13th afternoon. A 6ft swell from the SSE, a period of 7 seconds, and a moderate offshore wind from the SW. That’s a clean, fun wave with a combined energy of 789. That’s a good solid option.
The last few days of the forecast are a bit of a tease. Monday the 14th has a 4ft from the S with a very long 13-second period. That’s a groundswell, and with that period, it’ll have heaps of energy (724) and long gaps between sets. It’ll be better at a point or reef than a beach break. Tuesday the 15th morning has a 6ft from the E with a clean cross-off wind – that’s a decent option. Wednesday the 16th has a long-period swell again, 4ft from the S at 13 seconds, with moderate cross-off winds.
All in all, the standout is Wednesday morning the 2nd and Tuesday morning the 8th. For the real experienced, Monday the 7th has the size. The long-range stuff from the 13th onwards is promising but less certain.
Rusty out.

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.
