The Lowdown

Alright, surfers, Rusty here. Let’s have a look at what’s coming up for our local sandbar.

Alright, there’s one main spot on the menu for the next 16 days, and that’s Barrinha. It’s fairly exposed to the swell and picks up a bit of size, but it's not a non-stop affair. We’ve got a bit of a slow start, but the middle of the week is looking promising.

The first real action kicks off on Tuesday morning. It’s not the cleanest start with a risk of thunderstorms and a moderate breeze from the SW, but the swell is up to 5 ft from the ESE. The period is short at 8 seconds, so it'll be a bit chop-happy, but the combined energy is moderate (264). It’s surfable, but a bit ordinary.

The standout of the whole run is Wednesday morning, September 2nd. The sky clears, the wind swings to a light SW breeze which is cross-offshore, and the swell jumps to a solid 7 ft from the SE. The period lengthens to 10 seconds, giving it some proper push. The combined energy is strong (712). This is the kind of morning that gets you out of bed early. Conditions are clean, and the wave quality is expected to be very good. This is your best bet for the whole forecast period.

Thursday, September 3rd, the swell drops back a bit, and the wind goes cross-shore, making conditions poor. Friday and Saturday are small, with 3 ft or less on offer, and the wind is still messy. The swell energy is weak in the range (84-170). It’s not really worth a paddle.

Sunday, September 6th, the swell starts to build again. The morning is 7 ft from the S, but the period is just 8 seconds, so it’s a bit lumpy. The afternoon pushes up to 8 ft from the S with a 9-second period, and the combined energy is very strong (1099). At that size, it’s getting into the expert-only zone, and with a moderate breeze, it’s not going to be clean. It’s marginal.

The next real chance of a clean wave comes on Tuesday, September 8th. The swell is still a consistent 5 ft from the SSE, but the wind goes completely glassy – first from the SE then from the ENE. Combined energy is moderate (357-300). It’s a good day for a longboard or a fun fish, with clean, glassy conditions.

After that, the long-range forecast gets messy. The wind turns onshore and strong, with a cross-on chop from the NNE. The swell stays around 5 ft to 3 ft but with a long period of 12 seconds, which is a groundswell – it’s got energy but it’s likely to be a bit straight and hard to handle at a beach break like Barrinha. Conditions are poor. That stretch from Wednesday, September 9th through to Saturday, September 12th is a write-off.

There’s a flicker of hope on Monday, September 14th morning. The wind is offshore from the W, light breeze, and the swell is 3 ft from the S with an 11-second period. The combined energy is moderate (397). It’s clean and should offer some nice, long lines. That’s a solid option for the second week.

The very end of the run, around Wednesday, September 16th, is small and clean again in the morning, with 3 ft from the N and a very short period of 5 seconds. It’s a glassy, fun-size day, but not much grunt.

So, the clear winner is Wednesday morning, September 2nd. That’s the one to plan for. The Monday the 14th is a promising backup, but it’s further out so keep an eye on it.

Water temp is around 66°F, which is just about average for the time of year. No major surprises there.

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.
