The Lowdown
Alright, Rusty here. Let's have a look at what we've got cooking over the next couple of weeks.
Right off the bat, we're looking at a bit of a slow start. The surf on Monday the 31st is real marginal with a messy wind on it, so we're skipping that. Things actually start to look up pretty quickly though. The standout period kicks off on Tuesday morning, September 1st. We've got a clean 6ft swell pushing in from the ESE with an 8-second period, and the wind is offshore from the WSW at 9 mph. That's gonna make for some clean, fun waves at Barrinha. The water temp is sitting at 66°F, which is pretty much bang on average for this time of year, so no surprises there.
That Tuesday morning session is our first true highlight, but Wednesday morning, September 2nd, is looking even better. The swell drops just a touch to 5ft, but the period stretches out to 9 seconds, giving the waves a bit more shape and punch. The combined energy is solid at (427), and with that clean offshore wind from the WSW at a light 6 mph, the conditions are going to be primo. This is your best bet for the first half of the week—get out there.
After that, we hit a bit of a lull. The surf drops off significantly from Thursday the 3rd onwards, getting small and messy with strong cross-onshore winds. There's a gap of a few days with nothing really worth paddling out for.
Now, looking further down the line, there's another spike worth noting. Monday morning, September 7th, brings in a proper pulse of energy. We're looking at a 5ft swell from the South with a 10-second period, and the combined energy is pumping at (998)—that's strong, powerful wave energy. The morning winds are offshore from the SW at 9 mph, which should keep things clean. This one is a bit further out, so there's always some uncertainty, but it’s a promising setup for a solid session.
Later on, Sunday morning, September 13th, shows another clean option with a 5ft SSE swell and light offshore winds from the SW at 6 mph. The energy is decent at (308), and while it's not a monster, it's a good option for a fun Sunday surf if the long-range forecast holds.
So, to sum it up: the best windows are Wednesday morning, September 2nd for the most reliable clean fun, and keep an eye on Monday morning, September 7th for the bigger, more powerful swell.
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.
