The Lowdown

Alright folks, Rusty here again, giving it to you in feet and miles. We got a real mixed forecast for Barrinha coming up. Starts with some alright Friday morning waves, then a long dead spell, and maybe a glimmer in the second week.

Friday the 21st of August morning is our opener. Barrinha is looking at clean chest-to-head high surf at 5ft, from the SSW with a short period of 7 seconds. The wind is a gentle cross-offshore breeze, keeping those faces clean. The combined wave energy is moderate. It's a decent morning for the intermediates.

But it changes quick. That Friday afternoon, the swell jumps to 7ft from the S, but the wind goes to 16 mph, ruining the quality. Write that session off.

Saturday the 22nd has potential. The morning is marginal with an 8ft S swell and 9-second period, but the afternoon looks way better. Saturday afternoon, the swell drops a bit to 8ft from the S, the period stretches to a nice 10 seconds, the wind is light, and the wave energy is strong. This is clean and solid for you experienced surfers.

Sunday the 23rd morning is where the real standout sits. The swell is a clean 6ft from the S, but the period is a juicy 12 seconds – that's real groundswell. The wind is glassy, almost calm, and the wave energy is strong. This is a great session. The light offshore and longer period will set up good lines. Remember, that long period might make it a bit straight at a beach break, so pick your peak. The afternoon turns into a cross-shore mess.

Now, Monday the 24th of August morning is a beast. We're looking at a massive 10ft swell from the S with a very long period of 16 seconds. The wave energy is off the charts. The wind is clean. But this is way too big for this break. Unless you're a hardcore expert, stay on the beach. Don't even think about it.

Then the bottom falls out. From Monday the 24th afternoon all the way through to Monday the 1st of September, the conditions turn poor. We're looking at a solid week of onshore winds, weaker southerly swells, and finally a drop-off to tiny, messy waves. Most days are flat or blown out. Tuesday the 1st of September afternoon shows a glimpse of 8ft swell, but the wind is cranking at 19 mph, making it a total mess. This stretch is a kite-surfing dream for the strong wind, but not for us.

There is a glimmer into the second week. Wednesday the 2nd of September morning brings a real spark. The wind goes offshore, the swell is a manageable 7ft from the SSE with a period of 10 seconds, and the wave energy is strong. The forecast says very good conditions. That is the best bet in the whole long-range outlook. After that, the onshore winds return and the swell fades again into the weekend of the 5th of September.

So to wrap it up: your best windows are Saturday afternoon the 22nd, and especially Sunday morning the 23rd of August for the clean, glassy lines. If you can wait, Wednesday the 2nd of September morning looks very promising, but that's far out, so keep your fingers crossed.

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.
