The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for Barrinha over the next couple of weeks.
Right off the bat, things are pretty flat and messy. Wednesday and Thursday this week are a write-off – tiny swell, cross-onshore wind, just not worth paddling out for. You’d be better off waxing your board for another day.
Friday morning the 21st is where it starts to get interesting. We’ve got a clean 5ft swell rolling in from the SSW with a short period of 7 seconds, but light offshore wind from the SW will keep things tidy. The wave energy is moderate (288), and while the period is short, it’ll be a fun, punchy option for intermediate surfers. That afternoon sees a bump to 6ft from the S, but a moderate breeze makes it a bit more of a handful – still clean, but only worth a look if you’re keen.
The standout window looks like Saturday the 22nd through Sunday the 23rd. Saturday morning delivers 6ft of SSW swell with a gentle cross-off breeze – clean conditions and strong wave energy (739). Sunday morning holds 5ft from the S with a longer 10-second period and light winds. This is your best bet for quality, consistent waves that won’t be too wild. The water temperature is about average for this time of year, so no surprises there.
Now, Monday the 24th is a different beast. The morning glass-off is a dream, with a 10ft groundswell from the S and a very long 13-second period. The wave energy is huge (2722). This is proper expert territory – way too big for beginners and even intermediate surfers will be in over their heads. That long period groundswell will make it steep and powerful, best suited for a point or reef, not so much a beach break. The afternoon drops to 8ft but with onshore wind, so it gets messy.
After Monday, the swell backs off and the wind turns unfriendly. From Tuesday the 25th right through to the end of the first week of September, it’s mostly small, choppy, or onshore slop. There are a few windows of clean small waves, like Thursday afternoon the 27th with a tiny 2ft glass-off, but that’s really only for a longboard or a beginner having a splash. The energy stays weak (77). That stretch of nearly two weeks with no real quality surf is a long gap, but forecasts can always shift.
If you’ve got to pick a time, nail Saturday the 22nd morning or Sunday the 23rd morning. That’s the sweet spot. Friday the 21st morning is a close second. For the big stuff on Monday the 24th, only the experts should even look at it.
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.
