The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks. It’s a slow start, but there’s a real sleeper hit waiting for us later on.
Right now, the ocean’s pretty flat with a weak SE swell. The combined wave energy is only 171, so it’s weak. The water temp is sitting at 65°, which is right on the money for average this time of year. The first few days are a total bust for any decent waves, with tiny surf and ordinary conditions.
Wednesday the 5th offers a brief moment of hope with glassy conditions in the morning at Joaquina (sandbar), but the swell is only 2ft from the SE with a period of 10 seconds. The energy is a measly 98, so it’s barely worth wetting your suit. After that, we get a run of clean, offshore mornings, but the swell is just too small – 1ft and 0.7ft – to get excited about. You’ll be waiting a long time for a set.
The first real standout on the calendar is Saturday the 8th. The morning is looking good with a 4ft SSE swell running at a solid 13-second period. That’s a proper groundswell, and the combined energy jumps up to 569 (moderate wave energy). The wind is a light, cross-off breeze from the NNW. This is the sweet spot for Joaquina. The waves will be clean and have some push. It’s a sandbar, so with a long-period swell like this, it might wrap in a little straighter, but the quality should be there for an intermediate level. The water temp is still 65°, feeling normal. The afternoon cleans up even more with a light offshore, but the swell drops a touch to 3ft. Saturday morning is the pick of the first week.
Sunday the 9th gets ruined. The wind swings around to the south at 25 km/h, cross-on and choppy, making a mess of things despite the swell picking up to 5ft and then 7ft. The energy hits 1523 on Sunday afternoon, but with that onshore wind, it’s a groaner. That’s more of a kite-surfing setup than a paddling one.
We get a bit of a break with a crappy, windy pattern right through until the following weekend. Friday the 14th and Saturday the 15th see some cross-onshore winds and lumpy conditions. Saturday the 15th morning has a decent 6ft SE swell with a 13-second period (energy at 981), but it’s cross-on and choppy again. Not great.
Now, the real hidden gem might be on Tuesday the 19th. The day kicks off with glassy conditions and a tiny 1ft SE swell, but the period is a very long 18 seconds. That’s a seriously long groundswell. The energy is only 111, so it’s weak. But then Tuesday afternoon, the wind shifts to a light cross-off from the NNE, and the swell builds to 2ft with a 16-second period, energy jumping to 237. For a sandbar, a super-long period like that can be a bit tricky, but with the light, clean wind, the waves that do come through will be beautifully shaped and have plenty of power. This is a promising, long-range standout, but don’t bet the house on it yet.
After that, we’re back to windy, onshore slop to finish the run. So, to sum it up: your best bet is Saturday the 8th morning for the most reliable, clean surf, and keep an eye on Tuesday the 19th for a potential glassy, long-period session.
Rusty.

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.
