Alright, Rusty here. Let's get into it.

Look, I've scanned the charts for the next couple of weeks and to be brutally honest, it's a tough stretch for Armação. We've got a decent amount of time staring at flat, wind-chopped or just plain messy conditions. There are long gaps where you wouldn't even bother paddling out. The first real sniff of anything happens much later on, so don't get your hopes up for the near term.

The water is sitting at 61°F, which is a massive 5°F colder than what we'd normally expect for this time of year. You'll be wanting a thick steamer, that's for sure.

The first session that even registers is on Saturday, July 11th in the afternoon. We're looking at a tiny 2 ft swell from the north, but it's wrapping in with a nasty 9 mph cross-onshore breeze from the NNE. The wave energy is pitiful, just 12 (weak). It's going to be a bumpy, gutless mess. Not worth a second look.

We get a brief, tiny window of glassy conditions on Friday morning, July 10th. The wind is dead calm – glass – but the swell is laughable at 0.7 ft from the NNE with a short period of 4 seconds. The combined energy is only 2. You could probably paddle around but you won't catch a thing.

Then things go totally dead for a solid stretch. From Saturday afternoon all the way through to the end of the second week, it's a desert of flat, clean, but unsurfable conditions. There's a lot of offshore wind in that period, but no swell to go with it.

Finally, on Sunday, July 19th, we get a tiny bump. A 1 ft swell from the ENE with a period of 7 seconds pops up on the Sunday morning, but it's on a 6 mph cross-onshore breeze. The energy is still only 10. Still not enough to get excited about.

The only standout, and I use that term loosely, comes late on Monday, July 20th. The swell picks up to 6 ft from the ENE, with a period of 8 seconds. The combined energy jumps right up to 390 (moderate). The problem? It's sloppy. The wind is from the NNE at 9 mph, blowing right across the face, making it choppy. For this break, with that bump in size and the onshore wind, it's going to be a rumbly, messy affair. It's the best we've got in the whole 16 days, but even then, it’s not going to be clean. This is more of a session for a fun, beater board. There's nothing here for beginners with the swell pushing 6 ft, and it's just too messy to be a classic.

All in all, a pretty bleak run for Armação. Keep the board in the car for a better forecast.

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.
