The Lowdown
Alright folks, Rusty here. Let's have a look at what Joaquina's got cookin' for the next couple of weeks.
Staring at the charts, it’s a bit of a slow burn to start. The first week is pretty gutless. We’ve got a few days of tiny, weak dribble – nothing worth paddling out for. From the 2nd to the 8th of August, you’re looking at flat spells and choppy, cross-shore junk. The wind just won't cooperate, and the wave heights are struggling to hit 2 feet. It’s a real write-off for anyone with a surfboard. You’d be better off checking the kitesurfing conditions, because there’s more energy for that than for a proper paddle session.
Then things start to wake up. The real action kicks off on the 9th of August. Sunday morning will see a jump in swell height to 7 feet from the S, but it’s a bit messy. The afternoon, however, is a different story. We get a 5-foot SSE swell and the wind swings offshore, cleaning it right up. That’s our first proper window.
Now, here’s where we get excited. August 10th (Monday) is the standout. The morning serves up a clean 6-foot swell straight from the SSE, with a light offshore wind. That’s prime. The combined energy is a solid 970 – that’s proper, powerful groundswell. The period is 12 seconds so it’ll have some good shape and line up well on the sandbar. Monday afternoon stays clean at 6 feet from the SSE. The following morning, August 11th (Tuesday), is flat-out glassy with a 5-foot, 13-second SSE groundswell. The energy is still very strong at 711. This is that perfect window where you can paddle out easily between sets and get some long, lined-up waves. This could be the pick of the entire forecast for the confident intermediate.
Remember, this spot is Joaquina, and it's a very consistent sandbar. With a period over 15 seconds on the 11th and 12th, the swell is a proper long-period groundswell. It’ll bend and wrap nicely around the sandbars here, but it can make beach breaks a bit straight. The offshore winds on those days, particularly the glassy conditions, will keep it all tidy.
The quality holds for the next couple of days – the 12th still has a great 4-foot SSE groundswell with a gentle offshore in the morning. You’ll start to see it fade a bit after that, with cross-shore winds and smaller swell moving in.
Looking way out to the second week, Sunday the 16th and Monday the 17th of August look promising again. We’re looking at a 5-foot easterly swell with that cross-off wind keeping it clean. The energy is in the 300s, so it’s a solid, fun size, but we’re a bit far out to nail it perfectly. Promising, but treat it with caution.
So, for my money: if you can only pick one day, point the van at Monday the 10th or Tuesday the 11th of August. That’s your clean, powerful, glassy groundswell window. Get out there.
Rusty.

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.
