The Lowdown
Right then, gather 'round. Rusty here. Let's look at what's shaping up for Armacao over the next couple of weeks, and I gotta be straight with you—it's a tough stretch. We're looking at a long gap of no real surf to start, and even when something pops up, there's a catch.
The story for Armacao is pretty quiet for the first week. The guidance tells me this spot picks up swell best from the NE, so we're waiting for the ocean to point that way. Monday the 24th, the water is sitting at a normal 66° for this time of year.
Right now, it’s flat. Monday the 24th is dead calm in the morning with barely a ripple at 0.7 ft, but it’s from the wrong direction and there's no push. The afternoon glass-off amounts to nothing. Tuesday and Wednesday go by with nothing rideable, just light onshore junk. Thursday the 27th morning sees a pulse of 4 ft from the NE, with a period of only 6 seconds—that's weak windswell, and the cross-onshore wind will chop it up. Combined energy is moderate (145), but with the period so short and the wind trashing it, it'll be a messy closeout. Forget it. Friday the 28th afternoon shows a bigger 7 ft from the ENE at 8 seconds, with strong energy (502), but the same cross-onshore wind will just make for a washing machine. That's more of a kite-surfing setup if anything.
After Friday, the ocean goes quiet again. We have a run of days from Saturday the 29th right through to the middle of the following week with absolutely no surf on offer. Glassy conditions and flat spells.
There's finally a flicker on Tuesday the 1st of September afternoon. We get a 3 ft swell from the ENE with a period of 10 seconds, pushing moderate energy (186), and clean cross-offshore winds from the SSE. That's surfable, but the swell is small and the direction is okay, not perfect. It's the best of a bad bunch.
Then another notable one pops up on Tuesday the 8th of September morning. We've got 4 ft from the NE, period of 5 seconds—again, weak and short period junk. The afternoon swings up to 5 ft from the NE at 6 seconds, with moderate energy (146) and clean cross-offshore winds. Still, it's short-period swell that will be peaky and not hold a great shape for long.
Honestly, the only two windows that look even remotely worth a paddle are the afternoon of September 1st and the afternoon of September 8th. Neither is a standout; they're just the least poor options. The first week is a write-off, and the second week has a couple of days that might save it from being a total blank. We just have to wait and see if the forecasts dial in closer to the time.
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.
