The Lowdown
Alright, Rusty here. Let's get into it.
We’ve got a bit of a slow start, then a proper pulse of energy rolling through. The first real chance to paddle out comes late Tuesday morning, the 25th of August. The water is sitting at 66°F, which is bang on average for the time of year – nothing unusual there.
The standout window is that Tuesday morning. Barrinha is going to be a treat. There’s a solid 6ft swell from the S, with a period of 12 seconds, giving it some real grunt. The combined energy is pumping at 1100 (moderate wave energy), and the wind is glassy from the NNW. That’s a recipe for some clean, lined-up waves. It’s a very consistent break, so you won’t be waiting long between sets. This is the pick of the forecast, no question. The shorebreak is going to be a bit full for beginners, though, so keep that in mind.
Tuesday afternoon the wind swings onshore from the NE at 9 mph, and the quality drops right off. Not worth it.
Wednesday the 26th brings a bigger swell, 8ft from the SSE with a 14-second period (a nice long groundswell), and the combined energy jumps to 2166 (strong wave energy). But the wind is a messy cross-onshore, making it lumpy and choppy. That’s a setup that looks more interesting for the kite surfers than paddle surfers. The size is pushing into expert-only territory at 8ft.
Thursday the 27th has the swell dropping to 6ft, but the wind is still a problem – cross-onshore and fresh. The surf is poor.
From Friday the 28th through the end of the month, we hit a flat spell. The swell drops to under 3ft, and the energy readings are weak (under 100). There’s a long gap of several days with nothing worth mentioning.
There’s a flicker of life on the 1st of September. The swell bumps back up to 7ft from the SSE, but with a shorter period of 8 seconds and a moderate cross-off wind. The conditions are marginal, and the combined energy is 437 (moderate). It’s surfable, but you’ll be working for it.
The 2nd of September has a 7ft swell from the SE with a 9-second period, and the wind is onshore. Not great.
The 3rd and 4th see the swell drop, but the wind cleans up. By Friday morning, the 4th of September, it’s glassy with a 3ft swell from the ESE. The energy is 221 (weak to moderate). It’s surfable, but pretty ordinary.
After that, it’s another quiet run of tiny, weak swells through the 9th of September. The energy dips to single digits. Nothing to get excited about.
So, the bottom line: Tuesday morning, the 25th of August, is your best bet. Get out there for the clean, glassy, 6ft S swell at Barrinha. The rest of the 16 days is mostly a write-off, but that one session is a ripper.

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.
