The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us.
It’s a slow start. For the next week, from today through to early next week, we’re looking at small, weak, mostly messy conditions. Nothing really worth paddling out for. The first few days are plagued with cross-onshore winds and tiny swell, so save your wax. There’s a real gap here with no solid recommendations until things finally start to turn.
The first glimmer of something rideable shows up on Tuesday morning, August 4th, at Barrinha. It’s not huge, but we’ll finally get a glassy morning with a clean 4 ft swell rolling in from the S. The combined energy is moderate at 315, so there’s a bit of push, and with the wind dead calm, it’ll be pretty as a picture. It’s not a standout for size or power, but it’ll be the cleanest we’ve seen in days. Keep your expectations in check though.
Now, the real one to circle on the calendar. The true standout arrives on Monday afternoon, August 10th, at Barrinha. We’re talking a solid, long-period S swell pushing 6 ft with a period of 14 seconds. That’s proper groundswell energy, and the combined energy reading is a whopping 1927 – that’s strong. The wind is light and cross-off, so expect clean, lined-up walls. This one is for experienced surfers only as it’s over the 5 ft mark; beginners should sit this one out. The offshore flow and long period should set up some excellent, powerful waves. This is the best on offer, hands down.
That clean, punchy energy carries over into Tuesday morning, August 11th, with another 6 ft S swell, a light offshore wind from the WSW, and a combined energy of 1116. Still giving it plenty of welly, but the rain might be spitting a touch.
For the rest of the second week, it stays active but winds get a little more cross-off. Wednesday the 12th and Thursday the 13th still have good S swell between 4 ft and 6 ft, but the wind picks up a notch, making it a bit less perfect than that Monday and Tuesday window.
For the water temp, it’s about average for the time of year, so no worries about a cold snap.
That’s the story. A frustratingly quiet first week, but a solid pulse of clean, powerful S swell to look forward to in the second. Keep your eye on that Monday-Tuesday window at Barrinha.
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.
