The Lowdown

Alright, let me break it down for you here at Barrinha over the next couple weeks. Water temp is sitting at 64°F, which is a bit colder than normal for this time of year—nothing crazy, but you’ll want a wetsuit.

Right now through the first few days, it’s looking flat and messy. That Friday morning (August 28th) has a little 3ft SSE swell, period 12 seconds, but the wind’s cross-on from the NNE at 12 mph, so it’s choppy and not worth it. Combined wave energy is 153 (moderate), but conditions are bad. Saturday the 29th is tiny—maybe 1ft at best—and weak. Sunday the 30th picks up a bit: 4ft from the east, short period of 8 seconds, but it’s rainy and the wind goes onshore in the afternoon. Energy is 234 (moderate), but it’s still not good.

The real action starts Tuesday, September 1st. Morning has 3ft from the ESE—still small. That afternoon though? Swell jumps to 10ft from the SSW, period 10 seconds, and the wind is cross-off from the SSW at 19 mph. The forecast says it’s actually too big for this break, so only for experienced surfers. Wave energy is 1635 (strong). Wednesday the 2nd is similar: 10ft from the south, period 11 seconds, again too big. Energy hits 1855 (strong).

If you’re an expert, Thursday morning September 3rd is your best bet. You get 7ft from the south, period 10 seconds, and glassy conditions—wind from the SSW at just 3 mph. That’s going to be clean as a whistle. Combined energy is 816 (moderate to strong). That’s your standout session.

After that, it drops off. Friday September 4th is small and choppy. There’s a lull over the weekend with some ordinary waves in the 2ft to 4ft range, but nothing special. Monday September 7th brings another big pulse: 8ft from the SSE, period 13 seconds (very long period), and light cross-off wind. That’s excellent for experienced surfers, but that long period will make it break a bit straight at a beach break like this—so keep that in mind. Energy is 2085 (strong to very strong).

The rest of the second week is a mix of marginal conditions and onshore wind. There’s a window on Thursday September 10th with 4ft from the SSE and offshore wind in the morning—clean, but small. The last few days from September 11th onward are mostly cross-on wind and choppy, with some bigger swell up to 8ft but ruined by the wind.

The standout days for Barrinha are Thursday morning September 3rd for glassy, clean surf at 7ft from the south, and Monday morning September 7th for a powerful, clean 8ft SSE swell—but that one’s only for the experienced. The rest is either too small, too windy, or too big for this break.

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.
