The Lowdown
Alright crew, Rusty here, giving you the straight talk on the next couple of weeks.
Honestly, it’s a tough stretch. We’re looking at a proper drought of surf for ages, with barely a ripple worth paddling for. It’s the kind of run that’ll have you staring at the horizon more than riding it. The first real sign of life doesn't show up until late in the game, so patience is the name of the game.
The first whisper of something rideable is a tiny 1.0ft swell on the morning of Tuesday, August 11th, but it’s so weak you’d be fighting for ankle-biters. The wind is offshore though, so it’s clean if you’re desperate. Things stay pretty flat and poor right through the next week, with only scraps of 1ft to 2ft showing up, usually with a cross-on wind messing it up. The water temp is sitting at a mild 67°F, which is pretty normal for this time of year, so no surprises there.
Now, the one bright spot, and it’s a doozy, is the afternoon of Monday, August 17th. The swell jumps up to a solid 10ft from the ENE with a period of 9 seconds. That’s a massive amount of energy heading our way. But here’s the catch, and it’s a big one: the forecast straight-up says the swell is predicted to be too big for this break. The wind is a cross-on shore, so it’s going to be a wild, churning mess. This is strictly for the absolute experts only, and even then, it’s more of a survival session than a fun one. The rest of the week after that fades back into nothing.
So, the honest truth? There’s no standout, no session to get excited about. The only event on the horizon is that massive pulse on the 17th, but it’s a beast for the brave or the foolhardy. Everything else is a flat, frustrating wait.
Rusty.

Information about the Armacao Surf forecast
The above surf forecast table for Armacao provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Armacao can be found by selecting the local surf guide option on the grey menu. Our Armacao 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 (Armacao) 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 Armacao 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.
Armacao is 19 km (12 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.
