The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We’ve got a slow start but the swell window opens up nicely as we head into the weekend. The first real action isn't until Friday morning, August 7th, with a small, clean, waist-high wave at Barrinha. It’s a bit weak with only 76 (weak energy) on the dial, but the cross-off wind from the south will keep it tidy. It’s a bit of a tease, really.
The gears shift on Saturday. The swell kicks up to a solid 7ft from the south, but the wind is all over the place. Saturday morning with a light north wind pushes it a bit cross, and the rain will be coming down. It’s not clean, but there’s a lot of energy in the water. The real standout window kicks off on Monday, August 10th. That morning, we’re looking at 8ft of south swell with a 12-second period. The combined energy is a massive 2726 (strong to very strong wave energy), and more importantly, the wind is offshore from the southwest. This is the pick of the week. For experienced surfers only at that size, but it’s going to be firing with deep, powerful lines. The water temp is sitting at 67°, which is about average for this time of year, nothing crazy.
Tuesday, August 11th, is the runner-up. The swell drops a touch to 6-7ft, but the wind goes glassy in the afternoon – absolutely dead calm. That’s a rare treat. The waves will be clean as a whistle, but watch for the long 12-second period; it’ll be a bit more powerful and those sets will have a bit more time between them, making the paddle out a bit easier.
The surf settles down through the middle of the week. Wednesday and Thursday look a bit messy with onshore winds chopping things up. The swell drops and the quality fades.
The next genuine highlight is Friday, August 14th. A solid 6-6ft south-southeast swell with a 13-second period, light winds, and clean conditions. The energy is about 1197 (moderate wave energy). It’s not the monster Monday was, but it’s a very good, clean day for a decent session.
We then hit a big gap. From the 16th of August onwards, the swell drops off a cliff. The energy readings fall into the double digits, and the wind turns onshore or cross-shore. There’s a tiny blip on Wednesday, August 19th, with a glassy morning and a 5ft south swell, but it’s short-lived and the wind turns bad again. After that, it’s flat and choppy all the way through to the end of the forecast. The combined energy for the 18th is only 29 (weak wave energy), so it’s a real dead zone. Don’t get your hopes up for the second week.
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.
