The Lowdown
Alright, Rusty here breaking down the next couple weeks for ya.
First up, a dry spell. From Sunday the 16th straight through Wednesday the 19th, the ocean is basically flat. Tiny, messy junk if you even bother. A solid four-day window where you’re better off waxing your board for later.
Friday the 21st finally offers something. It’s a slow starter, but the afternoon brings chest-high waves (4 ft) from the south, clean-faced with moderate energy. Not epic, but a nice way to get back in the water.
Now, the real action kicks off Saturday the 22nd. Morning sees solid 6 ft south swell with light breeze keeping things clean. The combined energy is a solid 528, and the period is 9 seconds, giving it good push. This is the pick of the week – good size, clean wind, and consistent sets. Expect a crowd, but it’s worth it.
Sunday the 23rd keeps it rolling with the same 6 ft south swell, but the period stretches to 12 seconds, kicking the energy up to 915. The morning session is the cleanest, with light cross-off breezes. That longer period means more shape and energy between sets.
Come Monday the 24th, the ocean flexes hard. Swell jumps to 10 ft from the south with a 12-second period and energy reading 2376. That’s huge. Offshore wind in the morning cleans it up, but this is strictly for experts. If you're not a pro, stay on the sand.
Tuesday the 25th settles to 7 ft, but the period is a very long 14 seconds, and the afternoon goes dead glassy – zero wind. Energy is a massive 1729. This is a rare, powerful window for experienced surfers only. Crowds could be thick if the secret gets out.
Your last good look is Sunday morning the 30th, with 5 ft of clean, cross-off swell from the SSE and a 12-second period. Energy sits at 877. It's a long ways off, so keep it on the radar but don't hold your breath.
Best call? Saturday morning the 22nd for the best all-around fun. For the big guns, Tuesday afternoon the 25th is a glassy dream.
Rusty out.

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.
