The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next 16 days at Joaquina. We're in for a slow start, so don't be in a rush to grab your board.
The first week is pretty flat and ordinary. From Sunday the 2nd right through the following Saturday the 8th, the swell is tiny and the wind is mostly messy. You'll see a few days with a little bump – like Tuesday morning the 4th with a 2ft SSE swell, and the combined energy is a weak 136 (moderate wave energy). But it's just not worth paddling out for. The wind is cross-offshore on the 4th, which is clean, but the waves are just too small. There's a real gap here with no good surf on offer.
Things start to get a bit more interesting around the second week. On Monday the 10th, the swell picks up to 5ft from the SSE, but the wind is a cross-on, so it's messy. The combined energy is 322, which is moderate. That's still a pass. Tuesday the 11th is the first real standout. We've got a 6ft SSE swell in the morning, bumping to 6ft in the afternoon, with a period of 13 to 14 seconds. That's a proper groundswell. The combined energy jumps to 867 in the morning and a strong 1212 in the afternoon. The wind is light cross-on, so it'll be a bit bumpy, but there's some real power in the water. It's an intermediate spot, so this size is fine for most, but it's not a beginner's day.
Wednesday the 12th keeps the energy going with a 7ft S swell in the afternoon and a combined energy of 1764 (very strong). But the wind is a moderate cross-on, making it choppy. The swell is getting big, bordering on expert territory. By Thursday the 13th, the swell drops back to 5ft, but the wind is still a moderate cross-on. It's a bit of a messy week overall.
The real standout, if you've got the skill, is Tuesday the 11th. That 6ft, 14-second groundswell from the SSE with light cross-on wind is the best energy we see. The direction is a bit off from the optimum SE, but the power is there. It's a very consistent break, so you'll get waves. Crowds are often an issue at Joaquina, so expect company.
For the rest of the run, the swell drops off again from Saturday the 15th onward, with 2ft to 4ft swells and clean cross-off winds, but the energy is weak to moderate. The 17th has a 4ft E swell with a clean cross-off, but it's a short 8-second period, so it's a bit weak.
The water temperature is sitting at 65°F, which is about average for the time of year, with a small anomaly of -0.5°F. Nothing to worry about there.
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.
