The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a bit of a rollercoaster ahead, but there is some gold to be found if you're willing to wait for it.
The first real action kicks off on Sunday morning, the 30th of August. It’s a bit of a slow start with a small 4ft easterly swell at Barrinha. The water is sitting at 66°, which is about right for this time of year. The real story that morning is the absolute glass – zero wind, just a light rain. It's surfable, but you'll be working for it on those short 8-second waves. The combined energy is a moderate 178 – it's there, but it's not firing. The afternoon gets a bit messy with the wind swinging, so don't expect much after lunch.
Monday morning, the 31st, is a different beast. The swell jumps to a solid 8ft from the east, and the energy is cranking at 632 (moderate-to-strong). It's glassy again, with a light SE breeze. This is a proper session for the intermediates, but the heavy rain might put a damper on the vibe. It’s a significant step up from the day before.
Tuesday, the 1st of September, is the standout of this first week. The morning is absolutely mint. We’ve got a clean 8ft swell from the ESE, a glassy surface with a light WSW wind, and the energy is pumping at 721. This is the kind of morning you call in sick for. The conditions are dialed. The afternoon holds up too, with a clean 6ft wave and a cross-off wind, but the morning is the real magic window.
The middle of the week, from Wednesday the 2nd through to Friday the 4th, is a write-off. The wind gets messy, the swell drops, and the quality goes out the window. You’re looking at a few days of poor conditions with cross-onshore junk. Save your energy.
Things get interesting again on Sunday, the 6th of September. The morning session at Barrinha sees a big 10ft southerly swell rolling in – this is big, expert-only territory. The energy reading is a massive 2608, which is very strong. The wind is offshore and clean. But here’s the thing: at this size, it’s likely too big for this break, so unless you’re a seasoned charger, it’s more of a spectacle. The afternoon is still a solid 8ft and clean, but the wind picks up.
After another quiet spell, the final call is for Monday, the 14th of September. The morning is looking like another beauty. A 7ft easterly swell with a 9-second period, light wind, and a solid energy rating of 770. Clean conditions. The afternoon gets even better with a 8ft swell and 10-second period, and the energy jumps to 954. The wind goes glassy in the afternoon. If you can hold out for this one, it looks like a proper payoff.
The best windows are without a doubt Tuesday morning, 1st September, and then the long-range promise of Monday, 14th September. The first one is a sure thing, the second one is a bit further out, but it’s got all the makings of a dream session.
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.
