The Lowdown

Alright, grab a coffee and listen up. Rusty here, and I’ve been looking at the charts for our local stretch. We’ve got a bit of a mixed bag over the next couple of weeks, but there’s some real magic to be had if you time it right.

The overall pattern kicks off with a nice, clean pulse of S swell early on, but things get messy through the middle before a solid window of clean surf opens up later. The water temp is sitting at 63°, which is a bit colder than normal for this time of year, so you might want to reach for the 4/3 instead of a spring suit.

The standout session, the one you’d be a fool to miss, is Wednesday morning, September 9th at Barrinha. The wind is dead calm, glassy, zero ripples – it doesn’t get any cleaner. You’ve got a 4 ft S swell running with a long 10-second period, and the combined energy is a solid 376 (moderate). It’s not a monster, but with that glass and the S swell coming straight down the pipe (optimum direction is SE, so it’s wrapping in nicely), it’s going to be lined up and fun. Expect some good surf conditions. It’s a very consistent break, so you won’t be waiting long between waves, but it can get crowded, so be ready to share.

The morning of Monday, September 21st is another one to circle. The wind swings back to glassy – SSW at 3 mph, dead calm. The swell is a smaller 4 ft from the E with an 8-second period, but with that glassy surface, it’ll be super clean. The energy is 347 (moderate). It’s a different direction than the optimum, but when it’s that clean, you’ll still be getting waves.

Now, for the tricky bits. The second half of the first week gets blown out. Thursday the 10th and Friday the 11th are messy with onshore winds and rain. Saturday the 12th actually has some size (8 ft) and clean conditions, but that’s a big S swell for a fairly exposed beach. The combined energy hits 991 (strong), so it’s got plenty of grunt. That’s expert territory for sure, and with onshore winds forecast later, it’s a high-risk window. The following week is a real wipeout – from the 13th through the 20th, it’s mostly poor conditions with cross-onshore winds and small, weak swell. A few days in there, like the 14th and 15th, have clean winds but the swell is either small or from a poor direction, so it’s a gamble.

The standout session is the Wednesday morning glass-off. The Monday the 21st glass-off is a close second. Get out there for the first one.

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.
