The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Joaquina over the next couple of weeks.
Right off the bat, I gotta be straight with you – the next week and a half is a bit of a write-off. The surf is tiny, the wind is messy, and it’s just not worth paddling out for. We’ve got a long dry spell from now until about the 10th of August. There will be a few odd moments of clean, glassy conditions on the 5th afternoon, but the swell is only 2ft with a weak energy reading of just 118 – it’s not gonna do much. Wait it out.
The real story starts on the 12th of August. That’s when things finally fire up. Wednesday morning the 12th brings a nice 5ft swell from the SE, period of 8 seconds, and glassy conditions with light SW wind. The combined energy hits a solid 520 (moderate) – that’s a proper surfable day. The water temp is about 66°F with a tiny anomaly of +0.4°F, so pretty average for this time of year. By the afternoon, the swell bumps up to 7ft from the SE, still glassy, and the energy jumps to 992 – that’s getting exciting. This is clean, punchy beach break action, and it’s the best on offer for the whole outlook.
The 13th and 14th keep the party going. Thursday the 13th morning has a 10ft SE swell under glassy skies, but that’s a big one – over 8ft, so that’s expert territory only. The energy is a massive 2378 (very strong), so you’ll feel the ocean pulsing. The afternoon settles back to 7ft SE with perfect glass, and energy at 816. Friday the 14th is the standout for intermediate to advanced crew: 5ft SE swell, glassy, calm winds, and a 505 energy reading. By the afternoon, you get a 5ft S swell with a period of 11 seconds and a big energy of 1025 – that’s a long period groundswell pushing in, and it’ll be perfect for the sandbar. The glassy conditions make it a dream. If you can only pick one session, that Friday afternoon is the one.
Overall, ignore the first week. The 12th and 14th are the true gems. The 12th is for everyone, the 14th afternoon is for the experienced crew looking for power. Stay patient, and you’ll be rewarded.

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.
