Table - best surf conditions forecast for Armacao over the next 16 days.
Alright, gang, Rusty here. Lookin’ at the next couple weeks, it’s a lean stretch. The water is a chilly 60°, which is a solid 7° colder than usual for this time of year—gonna need a thick wetsuit, no doubt.
From Thursday 9th July through the week of 13th July, it’s pretty much flat. The swell is tiny, the energy is weak (as low as 3 to 10 in the combined swell energy), and the wind is mostly cross-on or cross-off. There’s a glassy moment on Friday 10th morning, but the swell is only 1ft from the NE with a period of 5 seconds—barely a ripple. It’s a blank run, and for this spot, that’s not unusual when the conditions line up like this.
The first real pulse shows up late on Friday 17th July. The swell hits 5ft from the ENE with a period of 8 seconds, and the combined energy is 310 (moderate). The wind is light cross-on at 6 mph, so it’s not clean, but it’s the first wave we’ve seen. The swell direction is slightly off the optimum NE for Armacao, but it’s close enough to get some rideable waves. It’s a beginner-friendly size, but the cross-on wind will make it a little bumpy.
Saturday 18th July afternoon has a similar 6ft ENE swell, but the wind picks up to 12 mph cross-on, and the energy is 511 (strong). That’s a lot of power, but the chop will be messy. This one looks more like a kite-surfing day than a paddle-surfing day.
The best shot comes on Monday 20th July afternoon. The swell is 6ft from the ENE, period 9 seconds, and the combined energy is 591 (strong). The wind is cross-on at 12 mph, so it’s still a bit bumpy, but it’s the most powerful and consistent pulse of the forecast. It’s not perfect, but after a long dry spell, this is the one to target.
So, to sum it up: a long flat spell until Friday 17th July, then a few days of moderate to strong, choppy ENE swell. No classic day, but Monday 20th July afternoon is your best bet.
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.
