The Lowdown

Alright folks, Rusty here with the long-range look for our stretch of coast. Let's get straight into it for Barrinha.

The next 16 days start off pretty quiet, so don't rush to grab your board just yet. There’s a bit of a dry spell to kick things off. The first few days are looking flat and poor, with weak 1 to 2 ft swells and messy winds. You're looking at a gap of almost no real surf until Friday the 6th of September shows some promise.

Hold on though, because Sunday the 6th of September afternoon has a big spike – we've got a 10 ft south swell rolling in, with a solid combined energy (1419). That’s a lot of water moving. Thing is, for a spot like Barrinha, that's likely too much power and the wind is a fresh 19 mph cross-off. This setup looks more interesting for the kite crew than us paddle surfers. That combined energy figure is a big number, but the conditions are going to be unruly.

The standout real window for a good, manageable session is looking at Monday morning the 7th of September. The swell has dropped to a much friendlier 6 ft from the south, and we’ve got clean, offshore winds from the southwest at just 6 mph. The break is very consistent, so you won't be waiting around. The water temp is about 66°, which is pretty normal for this time of year. Be mindful that at this size and with a solid period around 10 seconds, it’s a good intermediate wave but might be a bit much for total beginners. The crowd factor is listed as "sometimes", so you might have company, but it won’t be a zoo. This is easily the cleanest and best-sized swell of the first week.

After that Monday high, things drop off again. Tuesday and Wednesday go a bit wonky with choppy cross-onshore winds, and then we hit another small gap from the 11th to the 13th of September where the surf is tiny and weak again—just 0.5 to 3 ft of messy energy.

Looking further ahead to the back half of the window, there’s a promising pulse to keep an eye on. Tuesday morning the 15th of September is flagged as very good. We’ve got a 5 ft swell from the south-southeast with a proper long period of 12 seconds, giving it good shape. The combined energy is a solid 888, and the wind is a light offshore breeze from the southwest at 6 mph. This one looks clean and punchy. It's a bit of a long-range call, so don't book the day off work just yet, but the signs are there.

Then on Thursday the 17th of September, the swell gets big again—8 ft from the south-southeast. The period is a very long 16 seconds, which is a true groundswell. The combined energy reading is huge at 2868. This is an expert-only wave at that size. For a beach break, a long period swell like this can be a bit too straight and closey, but the offshore wind from the SSW will help keep it clean. If you're a charger and the forecasts hold, that morning could be special, but it’s not one for the casual surfer.

So, to wrap it up: the pick of the bunch is Monday morning, September 7th for a classic, clean head-high session. For the brave, keep an eye on Thursday the 17th. The rest of the period is a mix of flat spells and average conditions, but that's the game. Forecasts can change, so stay tuned.

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.
