The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks at Barrinha. We’ve got a quiet start, but the back half of the outlook has some real potential, so don’t write it off just yet.
Right now, water temperature is sitting at 67°, which is about normal for this time of year – nothing out of the ordinary. The next few days are pretty flat and not worth your time. Sunday and Monday are all small, weak swells with poor conditions, and the combined energy is barely registering (2 to 60). Tuesday afternoon, 4 August, is the first hint of life. The swell is still small at 4 ft from the south, but the wind turns glassy, and the combined energy climbs to 343 – that’s moderate. It’s a marginal window, but if you’re desperate, you could get a few clean little waves.
Then we hit a dry spell. From Wednesday 5 August right through to Saturday 8 August, it’s all small, messy, and under 100 for combined energy. Not much to get excited about. The real story starts on Sunday 9 August. We get a solid 10 ft S swell rolling in, but here’s the catch – it’s too big for Barrinha. The combined energy blasts up to 2310 (strong) but the comment says the swell is predicted to be too big for this break. Monday morning 10 August is even bigger, with 10 ft from the south and combined energy at 5883 (very strong), but again, it’s too big for the spot. The wind is cross-on and choppy, so this is really only for experts, and even then, it’s a gamble.
The standout period comes Tuesday 11 August through Wednesday 12 August. Swell drops to a more manageable 7 ft to 6 ft from the south, with a period of 13 seconds – that’s a nice groundswell with real push. The combined energy is still strong (1329 to 1044), but the wind turns clean cross-off, which is a major positive. Tuesday afternoon has 7 ft from the south at 14 seconds, glassy cross-off wind, and the combined energy at 1444. Wednesday morning has 6 ft, 13 seconds, cross-off, and the comment says “expect very good surf conditions.” Wednesday afternoon is also clean with 5 ft from the south, 12 seconds, and combined energy at 738. This is the best window. The swell is a touch overhead, but it’s clean, consistent, and the wind is offshore. Just be aware that with a longer period like 13-14 seconds, the sets will have more gap between them, making the paddle out easier.
After that, it drops off. Thursday 13 August is still rideable (5 ft to 6 ft) but the wind turns onshore, making it choppy. From Friday 14 August onward, the energy fades fast, and it’s back to small, poor conditions all the way through to Monday 17 August. The last week is a bust.
The best on offer is definitely Wednesday 12 August. The swell is 5 ft to 6 ft from the south, offshore wind, clean, and the combined energy is strong. That’s the one to aim for. Tuesday 11 August is also a solid option, especially if you want a bit more size. Everything else is either too small, too big, or too windy.
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.
