The Lowdown
Alright, surfers, ol' Rusty here with a look at what Joaquina's got cookin' for us over the next couple of weeks. We've got a solid stretch of swell ahead, but you've gotta pick your moments.
Joaquina is a sandbar setup, very consistent, and the water is sitting at a pretty normal 66°F for this time of year, so no wetsuit worries there.
The real standout is Wednesday morning, August 26th. We're looking at a solid 5ft swell pumping in from the SE, with a super long 15-second period. That's a proper groundswell. The wind is a light N at 9 mph, putting it as a cross-offshore. That's going to give us some clean, lined-up waves. The combined energy is a solid 1140, so there's plenty of push. This is for the experienced crew, though, as it's got some power.
The action starts to fade as we head into Thursday the 27th. The swell drops to 4ft in the morning, and while the wind is light and cross-off, the energy is down to 729. It's still surfable, but not as punchy. Things go downhill from Friday the 28th through to early September. The swell drops right off, and we've got a run of small, weak days with a lot of onshore wind. By Saturday the 29th, it's a complete write-off with choppy, cross-onshore junk.
We get a brief, tiny window of glassy conditions on Sunday afternoon, August 30th, but the swell is only 3ft with a short period. It's barely worth a paddle. The first week of September looks pretty bleak, with a lot of onshore wind and small, messy surf. The wind really cranks up on Thursday the 3rd, with a strong breeze from the S making it a total mess.
Now, lookin' further out, things start to get interesting again. On Monday the 7th of September, we see a late-afternoon flurry of activity with a 4ft E swell and glassy conditions. Then Tuesday the 8th morning is a solid bet: 5ft from the E with a light cross-off NW wind, giving us clean waves. The energy is moderate at 341. The big caveat here is the short 8-second period, so it might be a bit crumbly on the sandbar, but it's still the best option in the second week.
The long-range window around the 9th and 10th of September has some promise, with a longer period ESE swell (15-18 seconds) and consistent cross-off winds, but the swell height is only 2ft to 2ft. It's a promising sign for the long-term, but it'll be small.
So, to wrap it up: your best bet is Wednesday morning, August 26th. If you miss that, keep an eye on Monday afternoon and Tuesday morning, September 7th and 8th.
Rusty, signing off.

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.
