The Lowdown
G’day, Rusty here. It’s been a bit of a slow start at Barrinha, but hold onto your board—there’s some serious juice coming through if you’re patient.
Right now, the first few days are a mixed bag. Tuesday morning is small and ordinary with a messy 5ft from the ESE and a short 8-second period, plus a moderate breeze from the WSW (25 km/h). The whole swell energy is only 264—weak. Tuesday afternoon picks up a bit to 7ft, but it’s from the SSE with a short 7-second period, and there’s a risk of thunderstorms. Not worth paddling out for. The real pick-me-up arrives Wednesday morning, 2nd September: a clean 7ft from the SE with a solid 9-second period, good cross-offshore wind at 10 km/h from the SW, and combined energy of 668. Conditions are “very good”—that’s your first real standout. The water temp is about average for this time of year, nothing wild.
The rest of this first week fades fast. Thursday and Friday see the swell drop to 4ft and smaller, with onshore winds straight from the N and NNE making it choppy as hell. By Saturday, it’s down to 3ft from the S, but only 8-second period and just 112 energy—barely surfable. Saturday afternoon and Sunday are still marginal, with the swell trying to build again but the quality isn’t there yet.
Then, Monday morning, 7th September—holy moly. The swell jumps to 7ft from the S with a 10-second period, clean offshore wind from the SW at just 15 km/h, and combined energy of 1478—strong, punchy stuff. The rating screams “excellent for experienced surfers.” This is a standout session: steep, fast, and powerful. It’s a bit much for beginners, but if you know what you’re doing, get out there. The crowds at Barrinha are “sometimes” busy, so you might have company, but it’s worth it.
Tuesday morning, 8th September is another gem: 6ft from the SSE, 11-second period (that’s a nice groundswell), and glassy conditions—wind is almost nil from the ESE at 5 km/h. Energy is 718, moderate to strong. That’s a clean, lined-up session for everyone intermediate and above. The swell size is manageable and the glassy surface will make it smooth as butter.
There’s a lull from the 9th to the 11th—the swell drops to tiny (1.0ft to 0.7ft) with onshore winds and choppy junk. Not worth looking at.
But the second week fires up big time. Saturday morning, 12th September: 7ft from the S, 11-second period, glassy again with wind from the SW at only 5 km/h, and energy of 1274—strong. This is “very good” conditions. The standout, though, is Saturday afternoon: 8ft from the S, 12-second period, combined energy of 1802, and only a light breeze. This is thick, powerful, and for experts only. Sunday morning, 13th September, pushes it even further: 8ft from the S with a long 13-second period, energy of 2572—very strong. That’s a big, heavy groundswell. It’ll be epic at this fairly exposed spot, but the long period means the sets will be widely spaced. If you’re on a point or reef you’ll love it; at a beach break, watch for it to close out.
Monday morning, 14th September is still solid at 7ft from the SSE, 12-second period, clean offshore from the SW, with 1102 energy. A good follow-up session. After that, from the 15th onward, the winds turn onshore from the NE and the swell drops fast—down to 3ft on Tuesday afternoon and 2ft by Wednesday, with strong winds making it messy. That’s the end of the run.
So, in short: the first few days are a write-off. The best on offer is Monday morning, 7th September (big, clean, offshore) and Saturday afternoon, 12th September (huge, glassy, powerful). If you can only pick one, go the Saturday afternoon for raw energy and a long-period groundswell. Just be ready for a serious paddle.
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.
