The Lowdown
Alright folks, Rusty here. Let’s get into it for Joaquina. We’re looking at a pretty quiet start to the outlook, with a real slow patch for the first few days. The good news is it does build into something cleaner later on, so don’t write the whole period off.
The first real surf worth paddling out for shows up on Tuesday morning, August 4th. We’re talking a small 2ft SSE swell with a moderate 112 units of energy. It’s not going to blow your mind, but there’s a light cross-offshore breeze keeping the surface clean. It’s a limp start, but it’s something.
Wednesday, August 5th, is much the same story – a tiny 2ft SSE swell, still cross-off, still clean. It’s ankle to knee high, but at least the wind is working with us. The energy is modest at 79 units, so don’t expect much push.
The pattern holds through Thursday morning, August 6th, with a 1ft SSE swell and light offshore winds. The water temp is about average for the time of year, so no surprises there.
Now, we hit a bit of a rough patch from Friday, August 7th, through the weekend. The swell does build – we see 5ft to 6ft SSE swells, and the energy spikes up to 1655 units on Sunday, August 9th. But the wind is a mess. Solid cross-onshore winds, rain showers, and lumpy conditions. That’s a hard pass for paddle surfing. Honestly, with that much wind and messy surf, it’s looking more like a kiteboarder’s playground than a surfer’s.
The real standout comes on Monday, August 10th. After a morning of marginal 5ft swell with cross-onshore wind, the afternoon turns glassy. We’ve got a 5ft SSE groundswell with a 14-second period, 912 units of energy, and glassy conditions. That’s clean, lined up, and has some punch. Joaquina’s sandbars should handle that long period nicely, though it might be a bit full for the beach break. This is the best on offer – a solid, clean, chest-to-head-high session.
Tuesday, August 11th, keeps the good run going with a 4ft SSE swell, still glassy in the morning, turning offshore in the afternoon. The energy is still moderate at 452 units. Super clean, quiet, and inviting.
After that, the swell fades through the middle of the week, dropping back to 2ft by Wednesday, August 12th, with offshore winds. It’s back to small, clean, and cruisy. The last few days of the outlook, from August 13th onward, drop off completely with almost no surf and poor wind, so your window is really from the 10th to the 12th.
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.
