The Lowdown
Alright, Rusty here again, this time for the imperial crew. Let’s break down the next 16 days.
I’ll be blunt: the surf is flat and forgettable for the whole run. Wave heights barely get above 3 ft, and the combined swell energy is weak – all readings are below 100, mostly in the double digits. This is a long, drawn-out period of small, weak surf. The first six days – from Tuesday the 15th right through Sunday the 20th – are a complete blank. Water temp is about 65°F, which is pretty much spot on for this time of year.
Your only real chance for a wave comes on Monday the 21st. During the morning, a 2ft ENE swell shows up. It’s tiny, but with a clean cross-off wind from the SSW, the surface should be glassy. Combined energy is still weak (73), so it’s just a small, clean crumble for a longboard. By the afternoon, the wind turns onshore and the quality drops.
From Tuesday the 22nd through Saturday the 26th, it’s the same story: tiny waves under 2ft, with cross and cross-off winds that keep things tidy but the waves have zero power. The swell energy drops way down.
Sunday the 27th sees the wind pick up to 18 mph from the south, which is cross-shore and will make the surface lumpy. The 2ft swell is barely worth looking at. This is more of a kite-surfing wind day than a paddle session.
The last hope is around Wednesday the 30th: a 3ft ENE swell with a cross-off wind from the NNW that will clean it up a bit. But the combined energy is still very weak (75).
So here’s your one true standout: Monday the 21st morning. A 2ft ENE swell, clean, but tiny. That’s as good as it gets. Praia Brava gets enough exposure from the east to see it, but the lack of size and energy means it’s only for the most patient surfer on a big board. Everything else is a dud. A long blank stretch at the start, and even the “better” days are pretty ordinary. Keep your expectations low and your wetsuit handy. Forecasts can change, but right now it’s a quiet run.
Rusty.

Information about the Praia Brava Surf forecast
The above surf forecast table for Praia Brava provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Brava can be found by selecting the local surf guide option on the grey menu. Our Praia Brava 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 (Praia Brava) 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 Praia Brava 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.
Praia Brava is 23 km (14 miles) from the city of Florianopolis. If you plan a holiday in Florianópolis, look for hotels and other accommodation in Florianopolis. Florianopolis has rooms for a wide range of budgets as well as car hire and transport links.
