The Lowdown

Righto, let’s have a look at what’s on offer for the next couple of weeks. We’ve got one main spot firing up, Barrinha. It’s a fairly exposed, very consistent intermediate wave that loves swell from the southeast. The water’s sitting at 66°F and is about average for the time of year, so nothing weird going on there.

Things kick off proper on Tuesday morning, 11 August, with a solid pulse of 7 ft S swell rolling in at 12 seconds. That’s a decent groundswell, and with cross-off winds from the southwest at just 3 mph, the face is going to be clean. The combined energy is pumping at 1277 (moderate), and the set-up looks great. The afternoon turns glassy with an ENE breeze at 3 mph – that’s a treat. The swell drops just a touch to 7 ft but it’s still clean and inviting.

Wednesday 12 August brings the first bit of grit – 12 mph northerlies cranking cross-on, making a mess of the 6 ft SSE swell. That’s a skip day for me.

Now Thursday 13 August, that’s the standout. Morning has a 7 ft S groundswell on 14 seconds, cross-off from the southwest, and the combined energy is up at 1531 (moderate strong). The wave comment says it’s excellent for experienced surfers – and it will be. That long period gives the waves shape and push but at a beach break it might be a little straight. Still, it’s clean, and a rare chance to score some proper lines. Afternoon the same story with a 13-second swell and light cross-off.

Friday 14 August morning is glassy and 5 ft from the south, 13 seconds, with only a slight air breeze. Clean and fun. The afternoon gets a 7 ft SSE swell with onshore wind – that’s a bit iffy, tide dependent.

Saturday 15 August sees a drop to 4 ft and then 5 ft with short 8-second period and choppy cross-on wind. Not your day.

Sunday and Monday, 16 and 17 August, are messy or tiny. The swell fades to 1.0 ft by Monday – a real lull.

We’ve got a long gap of flat or poor conditions from Sunday 16 through Friday 21 August. There’s a tiny pulse on Wednesday 19 with 2 ft S swell and offshore winds, but it’s really only knee-high.

Then into the second week: Saturday 22 and Sunday 23 look small and average. But Sunday 23 afternoon sparks up – 5 ft S swell at 12 seconds, very clean with glassy or light cross-off. That’s a late-session surprise.

Monday 24 afternoon brings a 7 ft S swell at 14 seconds – combined energy 1465 – but with cross winds. Might be a bit lumpy.

The real standout in the second week is Tuesday 25 August morning. A solid 10 ft SSE swell with a 16-second period – that’s a very long period groundswell. The combined energy is a massive 3863 (very strong). The wave comment warns it might be too big for this break, so this is strictly for experts. The wind is cross-on at 6 mph, but with that size and length, it’ll be heavy. Wednesday 26 and Thursday 27 still have overhead swell but the conditions are more marginal and cross-on. If you want a serious wave and you’re experienced, set your sights on the 25th. For the everyday surfer, Thursday 13 August is your best bet – clean, solid, and fun.

Stay patient, keep an eye on the sky.

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.
