The Lowdown
Alright, let’s get into it. The next couple of weeks are looking pretty bleak for us here at Armação. There’s a whole lot of nothing on the cards before we get any real surf, and even then, it might be a case of too much of a bad thing. We’re looking at a long stretch of flat, clean but useless conditions for the first few days. It’s not until the 18th that we see any kind of bump, and even that’s weak, short-period leftover stuff—nothing to get excited about.
The 18th brings in a small, weak swell from the ENE with a period around 6 seconds. Combined energy is a paltry 63 in the morning, building to 132 by the afternoon, but it’s messy and junky. Poor waves, honestly. The 19th is even worse—short, weak, onshore junk. Not worth your time.
Then we hit the big one. On the morning of the 20th, the swell jumps to a solid 9.8ft from the ENE, with a period of 9 seconds. The combined energy is a massive 1261—that’s some serious power. But here’s the catch: the wave comment says it’s predicted to be too big for this break. This is a setup where the sheer size and power are going to make it a mess, probably closing out and just dumping. It’s not a surfer’s friend; it’s a washing machine. Unless you’re a glutton for punishment, I’d give that one a wide berth. It looks far more interesting for kite surfers than paddle surfers.
After that, it’s more flatness. The 25th has some tiny, weak, wind-affected slop, and the 28th and 29th are just ankle-biters. The 29th morning is glassy, but with a 1ft swell and a period of 8 seconds, there’s just no push. You’d be floating around with nothing to ride.
So, the bottom line: there is no standout day here. The only real swell is too big and onshore for Armação, and everything else is too small. It’s a frustrating outlook, but that’s the way it goes sometimes. Forecasts can change, but right now, it’s looking like a two-week pause. Keep your board dry and wait for the next pulse.

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.
