The Lowdown
Alright, let’s break it down, mate. The only game in town is Barrinha. It’s a consistent, exposed spot that likes swell from the south-east. The water temp is about normal for this time of year, nothing to write home about.
The first few days are a total bust. From Thursday 27th through Saturday 29th August, it’s all onshore winds and tiny waves. Sunday 30th has a glassy 2ft swell but with a 5-second period, so no energy behind it. Don’t bother.
Monday 31st morning finally shows a pulse: 1.3m swell (4ft), glassy, with weak-moderate energy. The call is “surfable but ordinary.” It’s a start.
The real gold is from Tuesday 1st September to Wednesday 3rd September. Tuesday morning (1st) brings a 2.3m (8ft) SSW swell, 8 seconds, clean cross-offshore wind, and 788 energy – that’s a proper, punchy wave. Tuesday afternoon holds at 2.2m (7ft) with a clean S wind. Wednesday 2nd morning is the pick: 1.8m (6ft) SSE swell, 10 seconds, gentle cross-offshore wind, and 687 energy. The forecast says “very good surf conditions.” That’s the session to aim for. Thursday 3rd morning is also a beauty – 1.8m (6ft) S swell, 10 seconds, glassy calm, and 700 energy. Another “very good” call.
After that, it drops off fast. Friday 4th and Saturday 5th are poor or marginal again. There’s a brief window on Tuesday 8th September morning: glassy, 0.8m (3ft) SSE swell with a 13-second period, 236 energy – “surfable but ordinary” – and the afternoon is a good 0.9m (3ft) S swell with clean cross-offshore wind and 465 energy. That’s a nice longboard session.
Thursday 10th September morning is the last decent one: 1.4m (5ft) S swell, 8 seconds, glassy, with 474 energy and a “good surf conditions” call. Another morning to pencil in.
So, the absolute standout is Wednesday 2nd September morning and Thursday 3rd September morning. Clean, decent size, and the right wind. If you can only get wet once, make it that Wednesday. For the rest, it’s a waiting game.

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.
