The Lowdown
Alright, Rusty here. Let's talk about what's cooking at Joaquina.
The next couple of weeks are a real mixed bag. We're looking at a long stretch of small, pretty average conditions before a promising pulse of energy arrives in the second week. Don't get your hopes up for the first week, but hang in there, because there's a proper window of clean surf on the horizon.
We start off with a flat spell. From Tuesday the 28th right through to the 4th of August, it's a write-off. The swell is tiny, mostly under 2ft, and the wind is either onshore or creating cross-ripple. The wave energy is weak, sitting at under 120 for most of that time, often much less. The water temp is hanging around 65°, which is pretty normal for this time of year, so no surprises there.
The first real glimmer of hope comes on Tuesday, the 4th of August. The morning is looking alright. We’ve got a 3ft swell from the SSE, with a moderate combined energy of 209. The wind is a clean cross-offshore from the N, which will keep the surface tidy. It’s not huge, but it’s a definite step up from the nothing we’ve been looking at. The Wednesday morning on the 5th is also clean, but the swell is a little smaller.
Now, the real standout is Sunday, the 9th of August. The morning looks like a beauty. We’re looking at a 4ft swell from the S, and the wind is forecast to be glassy. That’s a recipe for the best conditions in the entire forecast. The energy is a solid 224. It’s not huge, but for a peaky sandbar, that glassy wind will make it super fun. The afternoon turns a bit cross-shore, so get in early.
But the big one, the one to circle on the calendar, is Monday, the 10th of August. The morning is where it all comes together. We’ve got a solid 3ft swell from the SSE, but the period jumps to 15 seconds. That’s a proper, long-period groundswell. The wind is a beautiful cross-offshore from the NNW. The combined energy is a whopping 513. This is the best swell of the bunch. That long period will wrap in nicely, but it’s a point break setup, so it might have a bit of lull between sets. The Tuesday morning on the 11th is also glassy with a similar swell, but the period drops a little.
So, the best bet is Monday the 10th of August. The morning at Joaquina is the pick of the entire forecast. The combo of a strong, long-period groundswell and clean cross-off wind is going to be special. Sunday the 9th is a very close second with that glassy morning. The earlier days are just not worth paddling out for.
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.
