The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking at Barrinha.

Right now, things are pretty flat and messy. The start of the week is a write-off with poor, onshore conditions and small, weak swell. We’ve got a few days of nothing much until things start to turn on Wednesday the 9th. That morning should see a small improvement – light cross-offshore wind from the SSW cleaning up the lines, with 4ft swell from the south, period around 10 seconds. It’s not huge, but it’ll be your best chance for a wave in this first stretch, and combined swell energy is moderate at (382). Don’t expect a crowd, but it can get busy here sometimes.

Thursday the 10th keeps the swell around, but the wind turns cross-onshore, making for bumpy conditions. It’s a bit of a waiting game until Saturday the 12th, when a solid pulse arrives. Saturday morning sees a jump to 8ft SSW swell, but the period is short at 8 seconds, and the combined swell energy ramps up to (1020). The winds are cleaning up though, with a light cross-offshore. By Saturday afternoon, it’s a different beast: 10ft from the S, period 10 seconds, and the swell energy jumps to a strong (1651). wind and tide are favorable, but this is getting big – over 8ft, so it’s strictly for the experienced crew only. Sunday the 13th holds size at 10ft with an 11-second period, and the energy is very strong at (3493). Winds stay clean, but again, this is expert territory.

Monday the 14th gets messy again with strong onshore winds and a drop in quality. Tuesday the 15th offers a real gem though – glassy conditions, offshore wind from the WSW, and a clean 3ft SE swell with a nice 12-second period. Combined energy is moderate (379). The water temp is about average for the time of year here, so nothing unusual to report. This will be a clean, fun, glassy morning for intermediate surfers.

The rest of the second week is a mix. Wednesday the 16th brings clean but smaller surf (3ft, S swell, 10 seconds), and Friday the 18th morning is another glassy session with 4ft SSE swell and 9-second period. Energy is moderate (318). After that, the patterns fall away into small, choppy conditions with onshore winds through the 19th, 20th, and 21st, with combined energy dropping below 200 – it’s weak and not worth paddling out for. A small pulse returns on Tuesday the 22nd with a clean 3ft easterly swell but only an 8-second period, surfable but nothing special.

Overall, the standout is Saturday afternoon, September 12th – but only if you’re an expert chasing a big, clean swell. The real highlight for most of us is Tuesday morning, September 15th – that glassy, long-period swell with light offshore winds is a beauty. Get it while it’s clean.

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.
