The Lowdown
Right then, let’s talk about Joaquina. Over the next couple of weeks, the swell is going to flicker on and off, but it’s not going to be a blockbuster period. The best of it really sits in this first weekend, so let’s get into it.
Friday the 14th is a bit of a tease. We’ve got a solid SSE groundswell pushing in at 3ft to 5ft, with a period of 13 seconds, so there’s some decent energy there (combined energy of 802 to 949). Problem is, we’ve got onshore wind and light rain, so it’s going to be lumpy and a bit of a battle. Not the cleanest, but if the tide plays ball, you might find a fun one.
Now, Saturday the 15th starts to look a bit more interesting. The swell drops slightly to 5ft – 5ft, but the period is short (7 seconds)—so it’s more of a local windswell. The wind swings to a light cross-offshore in the afternoon, and things clean up nicely. That afternoon session early Saturday is probably the pick of the first few days. Clean faces, small but workable. Morning on Sunday the 16th is also solid, with that same cross-off breeze and 4ft of east swell. That morning window is your best bet for some tidy, fun waves at Joaquina.
After that, things go quiet. From Monday the 17th right through to Thursday the 21st, we’re looking at a real lull—waist-high dribble at best. The combined energy drops to pathetic numbers (7 to 222), and the wind gets messy. Honestly, unless you’re happy on a foamie in ankle slop, you’d be better off doing something else.
Friday the 21st shows a tiny pulse of 3ft from the ESE, but it’s cross-onshore and marginal. Still small. Then another dry spell from the 22nd through the 25th. The swell is basically non-existent. Barely a ripple. If you’re a beginner, this is the definition of flat.
Things start to rumble again from Monday the 24th, but it’s not good. We get a jump in swell to 6ft on the Monday morning from the SSE, combined energy (518), but with a strong cross-onshore wind and light rain, it’ll be a choppy, blown-out mess. That’s more of a kite-surfing wind than a paddle-surfing setup.
The strongest pulse of the whole period surfaces Wednesday the 26th: 6ft from the ESE, combined energy (469). But again—cross-onshore wind, light rain, and that messy chop. It’s a shame because otherwise, it could be a proper session. Not the day for a standard shortboard unless you’re a glutton for punishment.
The very tail end, Friday the 28th morning, offers a glimmer: 4ft east swell with a clean cross-offshore breeze. Small, but the wind is right, so it’ll be glassy and fun if you’re not expecting much power.
Standout call: If you can get out there on Saturday the 15th afternoon or Sunday the 16th morning, that’s your window. Clean conditions, waist-to-chest high waves, and good vibes. For anything else in the second week, it’s too far out to rely on, and the charts look messy.
Water temp is about average for this time of year, nothing unusual to report.

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.
