The Lowdown

G’day, it’s Rusty. Let’s have a look at what’s coming up for Barrinha.

We’re in a bit of a flat spell to start with. Wednesday the 29th is a write-off, and the rest of the week pretty much stays the same. Thursday morning the 30th offers a tiny 2ft swell from the south, but it’s ordinary and not worth paddling for. Friday the 31st through Sunday the 2nd of August see the swell drop even further, down to barely 0.3ft, with poor conditions and onshore winds. It’s a frustrating gap of about four days with no real surf on offer.

Monday the 3rd of August brings a glimmer of hope. The morning is glassy, and there’s a 1ft swell from the SSE with a very long period of 15 seconds. That’s groundswell, and it’s clean. The wave energy is weak (87), but the glassy wind and the long period mean the waves will have some shape. This is more of a session for a longboard or a log, but it’s the first decent look.

Now, Tuesday the 4th of August is where things start to get interesting. The morning sees a 4ft south swell with an 11-second period, light cross-offshore winds, and the conditions are clean. The combined energy is moderate (334). It’s the standout of the first week. The swell is still small enough for intermediates, and the wind is sweet. The water temperature is 66°F, which is about average for this time of year.

The real standout, though, is Thursday the 13th of August. That morning, a 3ft south swell rolls in with a 12-second period and glassy, cross-offshore winds. The combined energy jumps to 479 – that’s moderate on the higher side, and it’s clean. The swell direction from the south is a good match for Barrinha’s optimum. The period is long enough to push some proper lines through. It’s the best on offer in the whole 16-day window. The afternoon holds a 4ft south swell with stronger energy (720) and light offshore winds, though the rain might dampen the vibe a little. Still, this is the one to aim for.

In between, there are a few other mornings worth a look. Wednesday the 5th of August is glassy with a 3ft south swell, and Thursday the 6th and Friday the 7th also have glassy starts with small but clean swell. The crowds here are sometimes around, so you might have company on the good days, but it’s not a madhouse.

The swell stays small to moderate through the end of the run, never pushing over 5ft, so it’s all good for intermediate surfers. The longer period swells (12 and 15 seconds) will be best at the point or reef, not so much if it’s a straight beach break. The 7-second swells later on are short-period and more messy, best avoided.

Keep an eye on Tuesday the 11th of August – the afternoon has a 4ft swell from the ESE with a genuine offshore wind, but the period is short (7 seconds), so it’ll be a bit crumbly and weak. Still, it’s offshore, so it’s clean.

Overall, the best call is Thursday the 13th of August, with the morning glass and the building energy. Get on it.

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.
