The Lowdown
G’day, I’m Rusty, and here’s your local surf outlook for the stretch ahead.
We’ve got a bit of a slow start across the board, but fair dinkum, there’s a couple of sessions that’ll get you wet and smiling. The first real action kicks off on Sunday, September 6th, and that’s where you’ll find the standout.
Barrinha is the only spot on the radar, and it’s a fairly exposed, consistent little break, so it’s got a pulse most of the time. The water temperature is sitting at 66°, which is bang on average for this time of year—nothing weird there.
The week starts average. Thursday and Friday (September 3rd and 4th) are a write-off—poor conditions with onshore wind and messy waves. Saturday (September 5th) is still a bit ordinary with rain and light cross-off wind, but the swell is a modest 4ft from the south, period around 8 seconds. The combined energy is weak to moderate (210), so it’s only really surfable but nothing to get excited about.
Now, Sunday September 6th morning is the first real highlight. The wind swings offshore from the southwest, light at 9 mph, and the swell is a clean 5ft from the south with a short period of 8 seconds. The combined energy bumps up to a moderate 289. It’s clean, glassy offshore conditions, and the break is known to be very consistent. The morning will be clear and sweet—just a heads up, crowds can happen here sometimes, so get in early.
Monday September 7th morning is the real standout. We’ve got a nice 7ft swell pushing in from the SSE, period 10 seconds, and the wind is offshore again from the southwest at 9 mph. The combined energy is strong at 844. That’s a lot of juice, and the conditions are forecast to be very good. The waves will be solid and clean, but at 7ft, it’s getting into intermediate-to-expert territory—beginners might want to sit this one out. The swell direction is a good match for the break’s optimum, and with offshore wind, it’ll be well-shaped.
The rest of the first week goes downhill. Tuesday (September 8th) brings onshore wind and chop, so that’s a no-go. Wednesday and Thursday (September 9th and 10th) are small and messy, with energy dropping to negligible levels. Friday September 11th morning has a decent 6ft E swell but cross-on wind spoils it.
The second week is a bit of a mixed bag with no real standouts. Saturday September 12th is tiny and glassy but almost flat (0.3ft). Sunday September 13th to Thursday September 17th sees some waist-high swell (3ft to 4ft) with clean cross-off winds, but the energy is moderate and the conditions are only ordinary. The period ranges from 11 to 13 seconds on some days, which is decent groundswell, but the size is small. Friday September 18th is poor again.
Overall, the best two windows are Sunday September 6th morning and Monday September 7th morning. If you can only paddle out once, make it Monday September 7th morning—that’s the pick of the entire 16 days. The rest of the run is mostly small or wind-affected, so don’t hold your breath after that.
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.
