The Lowdown

Alright folks, Rusty here, checking in with the local outlook for the coming days. It’s a bit of a slow start, but we’ve got a promising run of cleaner surf shaping up later, especially if you’re willing to wait for the weekend after next.

Right now, we’re in a flat spell. The water is 60° and sitting much colder than normal for this time of year, so you’ll want a decent wetsuit. For the first few days, from Friday the 17th through to Monday the 21st, it’s pretty much a write-off. The swell is tiny, barely a ripple, and the wind is mostly cross-onshore or choppy. There’s nothing worth paddling out for. You’ll be staring at a blank ocean.

Then on Tuesday the 22nd, things start to whisper. Wednesday morning the 22nd, we see a slight bump, but the conditions are still very ordinary. The real shift kicks off Wednesday afternoon the 22nd. The wind goes offshore out of the WSW at 6 mph, and we get a 4ft south swell with a 10-second period. The combined energy is moderate at 320, and it’s clean. This is the first proper window.

Thursday morning the 23rd is actually a standout. Glassy conditions, light W wind, 4ft swell from the SSE at 10 seconds, and energy at 326. It’s clean, it’s quiet, and that’s a solid window for a session at Barrinha.

Friday the 24th keeps the clean cross-off wind, with a 3ft south swell in the morning, but by the afternoon it jumps to 6ft with a short 8-second period. That’s getting a bit bumpy and a touch too much short-period energy for the casual surfer. It’s marginal.

The weekend of the 25th and 26th gets messy again with cross-onshore winds and choppy conditions, so we’ll skip that. Monday the 27th sees a return to offshore winds and a smaller, cleaner 3ft swell.

Now, the real news is further out. On Tuesday the 28th, the swell jumps to 8ft from the SE, with a combined energy of 1054 – that’s strong wave energy. But the wind is cross-off at 16 mph, and the conditions are marginal. Not ideal for a paddle.

But hold on. Wednesday the 29th is where it gets interesting. Offshore wind out of the SW at 3 mph, with a 6ft swell from the east. Then by afternoon, it goes glassy with a 5ft east swell. Both windows are clean, and the energy is still strong. That’s a very good day.

The absolute best, however, is the first of August. Saturday morning the 1st of August, we get a 5ft ESE swell with a 13-second period, cross-off wind, and clean conditions. The energy is 904 – strong. And then Saturday afternoon, it gets even better: 5ft ESE swell, 16-second period (that’s proper groundswell), light cross-off wind, and the energy is 1318. The surf will be powerful, clean, and have good shape. Barrinha will be the spot. Keep in mind that long period swell like this can break a bit straight at beach breaks, but with the right tide, it’ll be a treat.

Between the 22nd and the 1st, there’s about a week of on-and-off, but the clear winner is that first weekend of August. Don’t sleep on the Wednesday the 29th either, but the 1st is the standout.

That’s the story from here. Get out there when you can.

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.
