The Lowdown

Alright, Rusty here again. Let’s break it down in feet and degrees.

We start Saturday morning, September 5th, at Barrinha. It’s a mellow start with a 3ft swell from the south, light offshore wind from the WSW at 3 mph. The water’s a pleasant 66°, which is normal for the season. The wave energy is weak (209), so it’s a longboard session. Saturday afternoon, the swell bumps to 5ft, the wind is cross-off at 9 mph, and it cleans up nicely. That’s your afternoon session.

Sunday the 6th gets bigger. The morning has 8ft from the south, but the period is short at 8 seconds – it’s going to be lumpy. The cross-off wind is 12 mph, so it’s rideable, but the energy is moderate (829). By the afternoon, the period stretches to 10 seconds and the energy is strong (1347), but the wind is howling at 18 mph. That’s kite-surfing or jet-ski conditions, not paddle surfing.

Monday the 7th morning is clean. 6ft from the south with a 10-second period, light cross-off wind at 6 mph, and moderate energy (518). The afternoon turns messy with a cross-on wind.

Tuesday the 8th is a washout. Cross-on winds up to 15 mph, small swell, and energy down to 236. Stay home.

Now, a real gem. Wednesday the 9th morning is flat calm. Glass. The swell is 4ft from the south, but with a 12-second period. The energy is moderate (361). It’s clean, lined up, and perfect for a longboard. The water is still 66°. No crowds to worry about.

Thursday the 10th morning is also glass. A tiny 2ft from the SSE, but with a very long 15-second period. The energy is moderate (415). It’s slow, clean, and peeling. The afternoon turns onshore and gets choppy.

Friday the 11th and Saturday the 12th are a total flat spell. The swell drops to 1ft, the energy is a pathetic 33. Two days of nothing.

Sunday the 13th brings a sudden change. The morning has 5ft from the east, but the wind is offshore and strong at 18 mph. The energy is strong (998) and the period is 10 seconds. It’s clean but bumpy. The afternoon stays similar with 6ft from the ESE.

The absolute standout is Monday the 14th. The morning brings 8ft from the SE with an 11-second period, and a moderate offshore wind at 12 mph. The combined energy is a massive 2887. The afternoon is just as good: 8ft from the ESE, 9 mph cross-off wind, and energy of 2424. This is the one. It’s big, powerful, and clean. But at 8ft, it’s expert-only. The crowd will be there, and it’s dangerous for the inexperienced. The swell direction is close to the optimum for Barrinha, so the break will be firing.

Tuesday the 15th morning is glassy again with 6ft from the ESE. The energy is strong (910). It’s clean and fun, but not as powerful as the day before.

From Wednesday the 16th onwards, it’s a slow fade. The swell drops, the wind turns cross-on, and the energy dies. The last few days are poor – the energy on the 20th is only 67, with a fresh cross-on wind. That’s a solid 5-day gap of nothing.

So, your best bets are the glassy mornings on the 9th and 10th for clean, mellow waves, but the standout is Monday the 14th for the big, powerful, clean swell. That’s the one to plan for, but it’s for the experts only.

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.
