The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for us at Barrinha over the next couple of weeks.

We’ve got a bit of a mixed bag, but the standout window is looking like Monday, the 10th of August, with some proper grunt coming through. The water is sitting at 67°F which is pretty much normal for this time of year, so no nasty surprises there.

The first proper sniff of action is Friday afternoon, the 7th. We’ve got a 7ft swell from the S with a short period of 8 seconds. The wind is cross-off from the S at 16 mph, so it’ll be clean but a bit lumpy. The combined energy is moderate (582). It’s surfable, but it’s not the pick of the trip.

Saturday the 8th is a bit of a write-off. Morning brings rain and a cross-on wind from the N at 12 mph, making a mess of the 7ft S swell. The period jumps to 14 seconds, which is a long-period groundswell, but with that cross-on wind, it’s going to be choppy and ugly. The afternoon is slightly better with lighter winds, but still cross-on and fairly ordinary.

Sunday the 9th is a better prospect. Morning sees a 7ft S swell with a short 8-second period, but the wind is cross-off from the SSW at 12 mph, keeping things clean. The energy is moderate (835). The afternoon really picks up though: the swell bumps to 8ft from the S with a period of 11 seconds, and the wind drops to a gentle 9 mph from the S, staying cross-off. The combined energy jumps to a strong 2189. It’s still a bit marginal on the tide, but the waves will have more shape.

Now, here’s the one to circle. Monday morning, the 10th of August. This is the standout. We’ve got a 8ft swell from the S with a solid 13-second period, and the wind is offshore from the SW at a light 9 mph. The combined energy is strong (3839). This is excellent surf for experienced surfers, with clean, lined-up waves. The afternoon stays good with a 8ft S swell and 12-second period, but the wind switches to a cross-off from the SSW at 12 mph, so it’ll still be clean but a little more wind-affected.

Tuesday the 11th is a very good follow-up. Morning has a 7ft S swell with a 13-second period and offshore wind from the SW so light it’s barely a breeze (3 mph). The energy is moderate (1278). The afternoon is glassy—wind from the SSW at 3 mph, zero texture. That 7ft S swell at 12 seconds will be smooth as silk. Expect very good conditions.

Wednesday the 12th and Thursday the 13th are a bit of a downer. The wind swings to the north and east, bringing cross-on conditions and choppy surf. The swell stays around 6ft to 7ft, but the wind ruins it. Not worth paddling out.

Friday the 14th is a nice little return. Morning is glassy with a 5ft S swell at 13 seconds. The energy is moderate (878). The afternoon stays clean with a light cross-off breeze. These are the kind of days where you can just enjoy the ride without fighting the wind.

Saturday the 15th is similar. Light offshore wind in the morning, glassy in the afternoon, with a 5ft S swell. The period drops to 10 seconds, so it’s a bit less powerful, but still fun waves for a Saturday session.

From Sunday the 16th through to Wednesday the 19th, it goes quiet. The swell drops right off, down to 2ft to 3ft, with poor conditions and onshore winds. There’s a gap of several days where you’re better off leaving the board in the car.

Now, for the experts only. Thursday the 20th of August. A massive 15ft swell from the SSW with an 11-second period is forecast, with the combined energy hitting a massive 8699. The wind is glassy in the morning, but the swell is predicted to be too big for this break. This is a beast of a day, and only the most experienced should even think about it. The afternoon drops to 12ft with a 12-second period, but the wind is onshore from the NE at 12 mph, making it a messy, dangerous situation.

Friday the 21st and Saturday the 22nd are a step down, with 8ft to 5ft swells, but the wind is mostly cross-on or chaotic. The afternoon of the 22nd looks glassy with a 5ft SE swell, which could be a nice, mellow end to the run.

So, to wrap it up: Monday the 10th is your best shot – strong, clean S swell with offshore wind. Tuesday the 11th is a close second with glassy conditions. Don’t sleep on the 14th and 15th for a clean, fun session either. The rest is a waiting game.

Stay stoked,
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.
