The Lowdown
Alright, Rusty here again. Let’s get the local lowdown.
The first stretch is a dead zone. From Thursday the 30th of July all the way until Monday the 10th of August, it’s mostly flat and weak. You’ll see a few glassy mornings, like Thursday the 30th with 1.3ft of SSE swell and a 9-second period, but the energy is tiny (44). It’s rideable, but nothing to write home about. Sunday the 2nd of August afternoon is glassy, but the swell is still just 1.6ft. The whole first week is a bust for any real surf.
The real action kicks off on Tuesday the 11th of August. The highlight is Joaquina on Tuesday afternoon. We’re looking at a solid 5.6ft of SE groundswell with a very long 16-second period, and the wind is light and glassy from the NE. The combined energy is massive – 1917 – so this is serious, powerful stuff. The swell direction is SSE, not the perfect SE, but the quality of the wave and the clean conditions make this the best of the whole run. This is for experienced surfers only; 5.6ft with that long period will be a beast. Water temp is about normal for the time of year.
Wednesday the 12th of August morning is another strong session, with 4.6ft of SE swell at 14 seconds, glassy with a light E wind, and very strong energy (932). The afternoon keeps it going with 4.3ft from the SSE at 13 seconds, still glassy. Thursday the 13th of August morning offers clean 3.3ft SE swell at 12 seconds, with light offshore winds from the N. That’s a solid, fun day.
The one to aim for is Tuesday the 11th of August afternoon at Joaquina. That’s the standout. Just expect a crowd, as it’s often busy. For that kind of glassy, long-period groundswell, it’s worth it.

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.
