The Lowdown
Alright, Rusty here, let's have a look at what's coming our way.
Alright, so for this stretch, we've got a bit of a rough start. There's no surf worth paddling out for until Sunday morning, so that's a blank day right off the bat. The main spot on the cards is Barrinha.
Sunday, September 6th: We’re getting a solid push of swell to kick things off, but it’s a bit of a double-edged sword. Sunday morning, surf is a clean but chunky 2.5m from the South with a short, 8-second period. The wind is a cross-off from the SW at 30 km/h, which will keep things tidy, but that short period means it'll be a bit fat and bumpy. The energy is big at 963, so plenty of water moving, but it’s not the best shape. By the afternoon, it's even bigger at 3.0m from the S, swinging to a better 10-second period, and the energy jumps to 1509. The wind is still a cross-off. Honestly, by the afternoon, it's getting too big for most. This is expert territory, so if you're not on it, give it a miss.
Monday, September 7th: Monday morning is the big winner for the early part of the week. The swell backs off to a much more manageable 1.7m from the South, still with a decent 10-second period. The wind is a light cross-off from the SW at just 10 km/h. That's the call for the cleanest, most user-friendly waves of the first few days.
Tuesday, September 8th: A write-off. The wind swings onshore and the surf gets small and choppy. Stay on the beach.
Wednesday, September 9th: Now we're talking. Wednesday morning is a gem. We’ve got a clean 1.1m swell from the South with a 10-second period. The wind? Absolute glass. A light N at 5 km/h and the water is flat. This will be perfect for a longboard or a funboard.
Thursday, September 10th: Thursday morning is interesting. The swell drops to a tiny 0.7m, but the period stretches right out to a very long 16 seconds. That's a proper groundswell, and with a light cross-off from the SW, it’ll be glassy clean. The energy is moderate at 431, suggesting long, waiting sets. Good for a point or reef, but at a beach break, that long period might make it a little too straight. Still, a beautiful morning.
Friday & Saturday, September 11th & 12th: Friday morning is glassy but tiny (0.7m). Friday arvo is a complete dud with onshore rain. Saturday morning offers some hope with a moderate offshore wind from the SW at 20 km/h and a 1.3m swell. It’ll be clean but the period drops to 9 seconds.
Sunday, September 13th to Monday 14th: This is the big swell event. Sunday gets huge: 3.0m in the morning and a monstrous 4.0m in the afternoon from the SE. The energy readings are off the charts (2132 and 5717). This is way too big for nearly everyone. It's for the hardcore crew only. Monday still has 2.4m leftover, but with a cross-onshore wind making it choppy and poor.
Tuesday, September 15th: Tuesday morning offers a reprieve. Glassy conditions and a clean 1.6m from the ESE with a 9-second period. A solid, fun day after the big stuff.
Wednesday, September 16th: A bit bumpy. 2 to 1.9m from the S, but with a moderate cross-off wind. Clean but not perfect.
Thursday, September 17th: This is the standout of the entire outlook. Thursday morning at Barrinha is looking mint. We’ve got a solid 1.9m from the South, a 10-second period, and the wind is glass. Absolutely glass. The energy is strong at 1311, so there’s plenty of push. This is the session to circle on the calendar. It’s clean, it’s got power, and the conditions are spot on. This will be the best on offer.
Friday the 18th through Sunday the 21st: The second week tapers off. Friday is cross-onshore and choppy with 1.8m, not great. Saturday is small and poor (0.8m to 0.9m). Sunday looks tiny and weak, and Monday returns to small but clean conditions with a light cross-off. Not much to write home about in the second week.
So, the clear standouts are Wednesday morning, September 9th for a glassy longboard session, and Thursday morning, September 17th for the best combination of size and conditions. Don't miss that Thursday morning.
Water temp is around 19°, which is bang on average for the time of year, so a spring suit will do you fine.
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.
