The Lowdown

Alright, folks, Rusty here. Let's talk about the next couple of weeks at our local sandbar, Barrinha. It's a bit of a mixed bag, but we've got a few windows to get excited about.

The overall pattern is a slow start with a big, messy pulse early on, then a cleaner, more consistent run of swell through the middle of the second week. The water temp is sitting right around average for this time of year, so nothing out of the ordinary there.

We kick off on Sunday, September 6th, with a solid pulse of S swell, but it's a bit of a brute. The morning is a write-off – 8ft of S swell at 8 seconds, but it's all cross-off wind and the energy is moderate (831). The afternoon goes up to 10ft with a better 10-second period, and the energy is strong (1478), but honestly, it's just too big for this break. That's expert-only territory and the wind is still a bit messy.

Monday morning, September 7th, is where it starts to get interesting. We've got a clean 6ft S swell, period at 10 seconds, and the wind is offshore from the WSW. Combined energy is moderate (551). That's a proper, clean, surfable wave. The afternoon dies off a bit with onshore wind, so the morning is the window.

The middle of the week is a bit of a lull. Tuesday and Wednesday see the swell drop and the wind flips onshore, leaving us with soft, choppy conditions. The swell energy is weak to moderate. Thursday, September 10th, is a tiny day but a beautiful one. The morning is glassy – 2ft of S swell with a very long 16-second period, giving it a moderate energy (434) for its size. That's a clean, glassy, long-period groundswell. It'll be perfect for the longboard or a fun fish, but the sets will be very spread out.

Then we have a few days of nothing much. Friday and Saturday morning are flat and junky. But then Saturday afternoon, September 12th, throws a little surprise. The wind goes glassy, and the swell jumps to 6ft from the SSE at 9 seconds. The energy is moderate (591). That's a clean, fun-sized wave for the afternoon session.

Sunday, September 13th, brings another big pulse of SE swell, 8ft, but it's cross-shore and the energy is strong (1450). It's a lot of water moving but not clean. Monday, September 14th, is the biggest day of the run, with 10ft of ESE swell, but it's onshore and raining. The combined energy is very strong (4599), but it's completely blown out.

Now, here's the standout. Tuesday, September 15th, is the one to circle. The morning has 7ft of SSW swell at 8 seconds, but the wind is offshore from the WSW. The energy is strong (1278) and the forecast is for "very good surf conditions." The afternoon is also solid with 7ft of S swell at 9 seconds and clean cross-off wind. Both sessions are a go.

Wednesday, September 16th, is glassy in the morning with a clean 6ft SSE swell. The energy is moderate (597). It's a beautiful, clean, mid-sized morning. The end of the week builds again. Friday, September 18th, has a glassy morning with 5ft of S swell at a nice 12-second period. The energy is moderate (842), and it's looking like another session of "very good surf conditions."

The best bet on offer is Tuesday, September 15th, with that morning offshore wind and solid 7ft swell. The second best is the glassy morning of Friday, September 18th. Both are clean, well-sized, and have good energy. The glassy morning of Thursday, September 10th, is a beautiful longboard day.

The crowd factor is "sometimes" at Barrinha, so you might have some company but it's not a circus.

Rusty out.

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.
