The Lowdown
Alright, Rusty here. Let’s break down the surf for the next couple of weeks.
We’re starting off slow. The first few days are small and messy, not much to write home about. The first real chance to get wet comes on Thursday morning, July 30th, at Barrinha. It’s a clean but small south swell at 2ft with a 9-second period, and a light offshore breeze from the SW. Water temp is 66°F, right on the average for this time of year. The combined swell energy is weak at 91, so it’s a hunt for the little runners.
The weekend after that is a dud – tiny, onshore, and choppy. Not worth the wax. Monday, August 3rd, brings a tiny 1ft SSE swell with a long 15-second period, but it’s onshore and not really breaking. The afternoon sees a 5ft NE swell, but it’s short-period (6 seconds) and bumpy – better for the kite crew than the paddle crew.
The real gold is in the second week, starting Sunday, August 10th. On Monday, August 10th, we get a solid build: 3ft to 4ft from the south with a 13 to 14-second period. Winds are light offshore, and the energy jumps to 340 and then 561. That’s clean, lined-up surf.
Tuesday, August 11th, is for experts only. We’re looking at a massive 10ft south swell. The wind is glassy – dead calm in the afternoon – and the energy is enormous (1938 to 2718). This is too big for most, and at a beach break, that long-period groundswell will close out. Keep your eyes on it from the sand.
Wednesday, August 12th, is the sweet spot. The swell drops to 7ft in the morning and 6ft in the afternoon from the south, with an 11-second period. Energy is 1194 to 1438. Winds are light offshore or variable, and it’s clean. This is the pick of the week for strong intermediates.
Thursday, August 13th, is a glassy dream for the experienced. A 8ft to 8ft ESE swell with zero wind and glassy conditions. The energy is huge (2178 to 1615), and the direction is perfect for Barrinha. It’s going to be clean, powerful, and perfect for anyone comfortable in overhead surf. Crowds are possible, so get in early.
After that, Friday, August 14th, still has a 7ft to 6ft ESE swell, but the winds turn onshore and the quality drops. Still surfable, but not the highlight.
So, the first week is a slow start, but the second week has two proper standouts. The best on offer is Wednesday morning, August 12th, for the clean, powerful 7ft south swell, and Thursday morning, August 13th, for the glassy, perfect 8ft ESE swell. Get out there.
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.
