The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.

Overall, the setup is a bit of a slow burner. We’ve got a fair bit of small, wind-affected junk to wade through before some real quality shows up. The only spot on offer is Barrinha, and it’s a fairly exposed spot, so it catches just about anything. The water temp is sitting at a very normal 66° for the time of year – nothing weird going on there.

The next few days are a write-off, honestly. We’re looking at a string of small, weak swell with combined energy barely getting into the double digits. The wind is all over the place, mostly cross or cross-onshore, and the swell is tiny – 1ft to 3ft. It’s just not worth paddling out for. There’s a brief, clean window on Thursday morning the 30th with glassy conditions and a little 2ft S swell (energy 88), but it’s very ordinary. That’s the best of a bad bunch for a few days.

The real action doesn’t start kicking off until Tuesday the 4th of August. That morning, we see the first proper increase of the run. A solid 4ft S swell (energy 426) rolls in with glassy conditions. It’s a bit small for a standout, but it’s clean and fun. That window holds through Tuesday afternoon with a 4ft S swell and clean cross-off winds.

But the one to circle on your calendar is Wednesday morning the 12th of August. This is the standout. We’ve got a proper 7ft SSE groundswell pouring in with a very long period of 14 seconds (energy 2251) and clean offshore winds from the WSW. This is serious energy. The water will be super clean. That wave energy is massive. The swell direction is a good match for Barrinha. That said, at 7ft, this is getting into expert territory; it’s not for beginners. The long period will make for well-shaped, powerful lines, and with offshore wind, it’ll be an absolute treat for experienced surfers. The afternoon sees the wind swing a bit cross-on, which is a shame, but the morning is the clear pick.

After that, the swell stays chunky but gets a little messy for the end of the run. Thursday the 13th sees a 8ft to 8ft E swell (energy 1213 to 1964) but it’s cross-on and a bit choppy – still big, but not as clean.

In the short term, the dry spell is around 5 days before any decent, rideable surf shows up. And that one day on the 12th is your best bet by a long shot.

Stay frothy.
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.
