The Lowdown
Right, gather round. Rusty here. Let’s have a look at what’s coming down the line for our little patch of coast.
Honestly, mate, it’s a pretty grim start to this outlook. The first week is basically a write-off for a proper surf. The swell that’s around on Sunday the 19th and Monday the 20th is all over the place – about 5ft to 6ft from the NE, but with a short, weak period of 8 seconds and a combined energy reading of 564 to 637. It’s got that cross-onshore wind on it, so it’s just lumpy and messy. Not worth paddling out for. After that, we hit a massive flat spell. From Tuesday the 21st right through to the end of the month, there’s next to nothing. A few days of glassy conditions but no swell to speak of. It’s a proper dead run.
We finally get a bit of life back in the new week. On Saturday the 1st of August, we see a tiny pulse of 3ft from the ENE with a 5-second period, but it’s still poor. The real glimmer of hope, the only thing worth getting excited about in this whole 16-day window, comes on Sunday the 2nd of August. The morning session is your best bet. We’ve got a 3ft swell from the ENE, period is a bit better at 6 seconds, and the combined energy is moderate at 79. But the big win is the wind – it’s glassy, dead calm. That’s a major positive. It’ll be clean, but with that short period, the waves will be a bit soft and fat. It’s not a standout for power, but it’s the only time we get clean, surfable waves. The afternoon gets chopped up again by a 12 mph cross-onshore wind.
So, for the whole run, the one and only highlight is the glassy morning of Sunday the 2nd of August. It’s not gonna be epic, but it’ll be the best we’ve got. Don’t hold your breath for the rest of it.
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.
