The Lowdown
Righto, grab a coffee, let’s have a look at the next couple of weeks at Joaquina. It’s a sandbar setup, very consistent, exposed to the swell, and it likes it from the southeast. A crowd favourite, so expect it to be often busy. Water temp’s sitting around 66°, which is pretty much bang on average for this time of year, so no surprises there.
We kick off on Thursday the 3rd with some swell, but it's not happening. Thursday morning has 4ft of SE swell with an 11-second period, but a cross-offshore wind is making things tricky and the scores are low. The energy is moderate (360), but the conditions just aren’t cooperating. Thursday afternoon is even worse – poor surf, don't bother.
Friday the 4th through to Saturday the 5th is a write-off. Tiny swell, cross-onshore winds, choppy mess. The combined energy drops right down into the double digits for most of it – weak stuff. A gap of several days with no real recommendations.
Sunday the 6th sees a jump in size in the afternoon – 6ft from the SSE, but with a fresh cross-onshore wind (30 km/h) and a short 8-second period. That’s lumpy and messy, not worth a paddle.
Now, Monday the 7th is a standout. The morning is glassy as a mirror, with a solid 7ft swell from the SSE at 9 seconds. The combined energy is cranked right up (1101), but here’s the catch – the file says it’s predicted to be too big for this break. That’s expert-only territory. If you’re not on it, sit it out.
The rest of that week from Tuesday the 8th onwards goes quiet again. Small swell, cross or onshore winds, poor conditions. Energy levels are mostly low to moderate. We’re looking at another gap until the second week.
Monday the 14th shows some promise. The morning brings 5ft from the SSE, with a light cross-offshore breeze and clean conditions. Energy is solid (380), and the forecast says good surf. Not a monster, but it’s surfable and clean.
The real standout for this whole period is Tuesday the 15th. The morning is firing – 6ft of S swell, an offshore wind from the NNW at 10 km/h, glassy clean conditions, and the combined energy is pumping (707). That’s the best on offer. Afternoon turns average again.
Wednesday the 16th is glassy again in the morning but only 3ft, so small fun waves for the loggers.
Thursday the 17th morning has a clean 3ft wave with a 12-second period and cross-offshore breeze, decent for a grovel. But Thursday afternoon and Friday the 18th get messy with strong cross-onshore winds and big energy numbers (over 1000) – but those are wind-affected, so it’s a no-go.
Overall, the first week is mostly a bust. The real windows are Monday 7th morning for experts only, and Tuesday 15th morning for the best all-round clean, solid surf. After that, it fades again. Long-range looks promising but less certain.

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.
