Alright folks, Rusty here. Let’s have a look at what’s comin’ our way for the next couple of weeks.
Right off the bat, we’ve got a little window of opportunity before things get a bit messy. The standout session is shaping up for Wednesday the 2nd, in the morning at Barrinha. It’s not a massive day, but it’s the best we’ll see for a while. The swell is a clean 7 ft from the SE, with a period around 10 seconds, and the wind is a clean cross-offshore from the SW at 9 mph. The water is sitting at 66°F, which is pretty much bang on average for this time of year. The wave energy is moderate (881), and the conditions are looking clean. It’s not a world-beater, but it’s a solid, rideable morning. Expect crowds *sometimes* – it’s a known spot. The swell direction is a match for the optimum, so it’ll be working well.
After that, the week takes a turn. Thursday and Friday are a write-off with onshore winds pumping from the north and north-northeast, smashing up the 5 ft to 2 ft swell. The wave energy drops off a cliff, falling as low as 66. It’s a poor stretch of surf.
We get a bit of a tease on the weekend – Saturday morning has a 3 ft S swell with cross-off wind, but it’s only rated as ordinary, and the energy is weak (181). Sunday morning improves slightly with a 4 ft S swell and a proper offshore wind from the SW at 9 mph, which will keep it glassy, but the period is short (8 seconds) and the energy is still low. It’s surfable, but nothing to get excited about.
Then, on Monday the 7th, we get a bit of a pulse. The morning sees a 6 ft S swell (8-second period) with clean cross-off wind, and the afternoon builds to 6 ft S (9 seconds). The energy jumps up to 567 and 541, which is moderate. It’s labelled as “good,” but it’s not the best we’ll see. The wind is cross-off, so it’ll be clean, but the swell direction is a touch south of the optimum SE, so it might be a little wobbly.
After that, the forecast goes quiet again. From Tuesday the 8th through to the 13th, the wind is mostly onshore or cross-onshore from the north and northeast, and the swell is small and weak. The energy readings are in the double digits. There’s a few days there with virtually nothing worthwhile.
Now, here’s the real potential. Looking way out, Monday the 14th is promising. The morning shows a 6 ft E swell with cross-off wind, and the *afternoon* is the standout of the second week: a 6 ft E swell with a glassy, light breeze from the south at 6 mph. The energy is moderate (795) and the conditions are labelled “very good.” The swell direction is from the east, which is a solid match for the optimum SE. It’s a long way off, so keep an eye on it, but it’s the one to circle on the calendar.
Then Thursday the 17th morning is also a dark horse: a 5 ft ESE swell, period of 10 seconds, and absolutely glassy, dead calm conditions (0 mph wind). The energy is moderate (562) and it’s listed as “good.” That’s a potential epic morning paddle if the forecast holds.
So, to sum it up: the best bet in the short term is Wednesday morning, the 2nd. After that, hold out for Monday the 14th afternoon or Thursday the 17th morning – those are the ones that could be real gems.
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.
