The Lowdown
G'day, Rusty here, checkin' in from Joaquina. We've got a sixteen-day window ahead and it's a bit of a mixed bag, so let's get straight into it.
Kicking off Tuesday the 11th, the morning is pretty average. Swell's around 5ft from the SSE at 12 seconds, but that cross-on wind makes it feel messy. The energy's moderate at 628. The afternoon is where it gets interesting – the wind goes totally glassy, the swell holds at 4ft from the SSE. That's proper clean and will have some nice shape on those sandbars. It's the standout for the first week, no doubt.
Wednesday the 12th sees the swell drop a touch to 4ft, but the wind swings north and goes cross-offshore, keeping things clean. It's rideable but not the peak of the run. Things go downhill from Thursday the 13th into the weekend – we get cross-onshore winds, choppy conditions, and the waves just aren't playing ball. The swell drops right off from Sunday the 16th onwards, with heights barely scraping 3ft and the energy dipping into the double digits. There's a real dead stretch from Monday the 17th right through to Saturday the 23rd of August – mostly poor surf with weak little windswells and onshore crud. A couple of glassy mornings pop up on the 21st and 22nd, but the swell's only 2ft to 2ft, so it's more of a longboard or swim fin kind of day.
Now for the good stuff. The real standout is looking like Tuesday the 25th of August. We've got a solid 6ft groundswell from the SSE with a very long period of 16 seconds. The energy's strong at 1757. It's glassy all day, with light rain and next to no wind. That's proper, powerful surf for experienced surfers – a bit too meaty for the beginners, but for those who know what they're doing, it could be unreal. Wednesday the 26th holds similar energy, 5ft from the SE at 14 seconds, offshore winds in the morning, and clean waves. The period's still long, so those points and reefs will be the go – the beach might turn a bit straight with that much power.
Keep an eye on that Tuesday the 25th and Wednesday the 26th – that's where the magic's hiding. The rest of the run is pretty ordinary, but as we always say, forecasts shift, and a good one's coming.
Rusty out.

Information about the Joaquina Surf forecast
The above surf forecast table for Joaquina provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Joaquina can be found by selecting the local surf guide option on the grey menu. Our Joaquina 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 (Joaquina) 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 Joaquina 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.
Joaquina is 9 km (6 miles) from 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.
