The Lowdown
Alright, let’s break down Joaquina for the next few weeks.
The start is flat and disappointing. From Tuesday the 4th through Friday the 7th, the swell is tiny, 0.6 ft down to 0.6 ft, with combined energy weak as hell – 144 down to 17 (weak energy). The wind is cross-off, which is okay, but the waves are just not there. Thursday the 6th is especially poor with risk of thunderstorms.
Then we get a proper window. Saturday morning, the 8th of August, that’s the one. The wind is light offshore from the NW, a gentle 3 mph, and the swell is 4 ft out of the SSE with a long 15-second period. That’s groundswell, and the combined energy hits 610 (moderate-to-strong wave energy). That’s the best morning of the whole run – clean, lined up, and set to be a classic. Just know this spot gets busy, so expect company.
Sunday the 9th and Monday the 10th get trashed by a strong southerly wind, 16 mph, cross-on, turning the 4 ft swell into choppy junk. The energy is still there (410–489) but the wind ruins it.
The middle of the week goes quiet again. Tuesday the 11th through Thursday the 13th is mostly poor to marginal, but on Wednesday the 12th afternoon and Thursday the 13th morning, the wind goes cross-off and light, giving us clean 3 ft to 4 ft SSE swell. Surfable, but nothing special.
Then, on Saturday the 15th of August, we get another chance. Morning glass-off with zero wind, 4 ft ESE swell at 8 seconds. That’s short-period but clean, and combined energy is 295 (moderate). If you get out early, it’ll be fun despite the short period.
The final week, from the 16th to the 19th, is mixed. Sunday the 16th morning has a gentle offshore breeze and 3 ft E swell, but it’s short period (7 seconds) and the energy is weak (148). Then it’s mostly cross-on winds and choppy, poor surf until Tuesday the 18th, when the swell picks up to 5 ft–6 ft SE with a short 6-second period and combined energy climbing to 278 (moderate). The wind is cross-off and clean, but that short period makes it punchy – more interesting for kite surfing than a traditional paddle session.
So, bottom line: Saturday the 8th morning is your best bet. Saturday the 15th morning is another clean window, but the short period takes the edge off. The long-range stuff is promising but not certain.
The water temperature at Joaquina is about average for this time of year, nothing unusual.

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.
