The Lowdown

Alright folks, Rusty here, let’s break down what’s coming for our local stretch.

The water is sitting right around 66°F, which is pretty normal for this time of year, so nothing weird there.

First up, Barrinha on Monday morning, 31 August. We’ve got a 6ft swell from the east, with a short 8-second period, so it’s a bit crumbly. But the wind is glassy, light from the ESE at 3 mph, so the surface will be smooth. The combined energy is moderate (418), so there’s enough to get a few rides. A solid start.

Monday afternoon, the wind swings cross-on and the swell drops, so it’s not worth it. Tuesday morning, 1 September, cleans up with a light cross-off breeze, 5ft swell from the ESE, still short period. Rideable. Tuesday afternoon’s offshore wind is too strong at 22 mph, so skip it.

Wednesday morning, 2 September, is the pick of the first week. Offshore wind at 6 mph, a 6ft swell from the SE with a 9-second period, and solid energy (454). Clean and lined up. Wednesday afternoon turns cross-shore, so it’s messy.

Then a dry spell from Thursday, 3 September, through Saturday, 5 September. The surf is small, energy under 150, with waves around 2ft to 3ft. A few days of nothing.

Sunday, 6 September, afternoon picks up with a 7ft S swell, short period, and a light cross-off breeze. Energy jumps to 477, but it’s a bit lumpy.

The real standout is Monday, 7 September. Morning: 7ft S swell, 10-second period, moderate offshore wind at 12 mph, strong energy (945) – clean and powerful. Afternoon: 8ft S swell, 12-second period, same offshore wind, very strong energy (1447) – excellent for experienced surfers. This is the best session.

Tuesday, 8 September, holds at 7ft from the SSE, but the wind turns light cross-on, so less clean. Still plenty of energy (825).

After that, the swell fades again. From Wednesday, 9 September, onward, waves are small, messy, or under 3ft. Energy drops below 200. There’s a brief moment on Saturday, 12 September, morning with a 4ft E swell, glassy wind, and moderate energy (537), but it’s not a standout.

The best call is Monday afternoon, 7 September – big, clean, powerful swell for the experienced crew. The early week has some fun options, but the middle is a washout. Mark that Monday.

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.
