The Lowdown
Alright, let’s talk about the surf in terms you might be more familiar with.
The first few days are a total bust. Thursday and Friday are blown out, so don’t bother. The water temp is about 66°F, which is normal for this time of year. The first real glimmer of hope comes on Monday morning (September 7th). We’re looking at a 8ft swell from the SSE, with a light offshore breeze from the WSW at about 6 mph. The period is 9 seconds, so there’s some decent energy in the water (combined energy of 829). This is a solid intermediate wave, but at that size, it’s a bit much for beginners. Barrinha is a consistent break, but crowds can show up, so it’s worth getting there early.
The real prize, though, lands on Friday, September 18th (morning). That’s the one to wait for. We’ve got a 7ft swell from the S, with a 15-second period – that’s a long, powerful groundswell unloading serious energy (combined energy of 2079). The wind is a clean cross-off from the SW, and the conditions are absolutely prime for experienced surfers. The swell is over 8ft, so this is expert territory only. It’ll wrap and hold its shape beautifully at a reef or point. The afternoon holds up too, with a 6ft swell and glassy offshore winds. That’s the best of the whole forecast.
Before that, the Monday morning (7th) is the earlier highlight. The 13th (Sunday) shows a 8ft S swell with clean winds, but it’s a bit questionable. The 16th (Wednesday morning) is glassy and clean with a 4ft S swell – a nice, smaller option. The 17th (Thursday morning) is also glassy with a 5ft S swell, but it’s just a warm-up for the big day.
The 18th is the standout. The swell direction, the wind, the period – it’s all coming together. It’s a long way out, so don’t bet the farm on it, but right now it looks like a proper session.

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.
