The Lowdown
Alright folks, let's talk about Joaquina. This stretch of sandbar is a classic, very consistent and exposed to the swell, but we've got a bit of a slow start here. The first few days – Monday and Tuesday the 20th and 21st – are basically flat with tiny 0.3 to 0.7ft dribble and onshore or cross winds. Nothing to get excited about. Wednesday the 22nd is still tiny and messy. Then Thursday the 23rd we see a jump in size – 4 to 7ft from the SSE/S – but the wind is cross-onshore and choppy, so it's a write-off. The real window opens up on Friday the 24th. That afternoon brings a glassy 5ft SE swell with a period of 9 seconds, and the combined energy is a solid 306 – moderate, but clean. The wind is dead calm, so the surface will be like glass. This is your best bet for the whole outlook. The swell direction is right on the money – SE is what Joaquina loves. Keep in mind though, this spot gets crowded often, so get there early. Saturday the 25th and Sunday the 26th are messy again with cross winds and choppy conditions, even though Sunday morning has a bigger 6ft ESE swell – it's just not clean. Then Monday the 27th morning gives us another gem: 5ft ESE swell, glassy again, with 389 combined energy. That's a touch bigger and still very clean. The period is 10 seconds, so it's a nice little groundswell. After that, the size drops off through the rest of the week, with mostly small, ordinary waves and onshore winds. The last decent window is probably Sunday the 2nd of August afternoon with a 3ft SSE swell and clean conditions, but it's small. Overall, the standout is Friday the 24th afternoon, with Monday the 27th morning as a close second. The water temp is about average for this time of year, nothing unusual. So if you're keen, pencil in Friday afternoon – just watch the crowds.

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.
