Table - best surf conditions forecast for Joaquina over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what Joaquina has in store for us.
First thing you gotta know: the water is sitting at 62°F right now, which is a whopping 4°F colder than normal for this time of year. That’s a serious chill, so you’ll want a thick suit if you’re heading out.
The week kicks off with a pulse of solid groundswell. Wednesday afternoon the 8th sees a clean 2ft swell from the SSE with a long 12-second period and a combined energy of 333 (moderate). The wind is a light cross-off from the NNE at just 3 mph, so conditions are clean. It’s not huge, but it’s a good sign of things to come.
Thursday the 9th drops off a bit with smaller 2ft waves from the ESE, period around 10-11 seconds, and energy down to 120. The wind stays cross-off but picks up a little, getting a bit breeze by the afternoon. Just ordinary surf.
Now, here’s where it gets interesting. Friday morning the 10th is a standout. The swell is only 2ft from the ESE, but the period jumps to 14 seconds – that’s a proper groundswell. The combined energy is 208 (moderate), and the wind is glassy from the SW at 3 mph. That’s about as clean as it gets. The waves will be small but super lined up, perfect for a longboard or a fun log. Just keep in mind, with a period that long, it might break a bit too straight for a beach break like this, but for a mellow morning session, it’s the pick of the week.
Saturday the 11th is the real winner. Morning sees 4ft of ESE swell, 13-second period, and energy jumping to 451 (strong). The wind is glassy from the NW at 3 mph. That’s clean, powerful, and consistent. The afternoon holds up with 4ft, same direction, and a light cross-off from the north at 6 mph. This is the best on offer – solid size, clean conditions, and consistent sets. It’s not too big for intermediates, but beginners might find it a handful.
Sunday the 12th is more marginal. The swell hangs around 3-3ft from the SE, period 11-12 seconds, but the wind turns cross-on from the south, putting some texture on the surface. Still surfable, but not as clean.
Monday the 13th is a write-off. Strong cross-on winds from the south at 12-16 mph chop up the 2-2ft swell. Choppy and messy – not worth paddling out.
Tuesday the 14th through the rest of the week sees smaller surf, mostly 2-3ft from the ESE or SE, with periods dropping to 8-9 seconds. The wind is mostly cross-off or glassy in the mornings, so there are still clean windows for a wave, but the energy is low (around 100-140). Ordinary conditions.
By the end of the second week, from the 20th of July onwards, the swell completely fades. We’re talking 0.3ft waves with energy down to single digits. That’s flat. No recommendations there. The gap from the 20th to the 23rd is a dead run.
So, to wrap it up: Saturday the 11th is your best bet – biggest swell, cleanest conditions, and plenty of energy. Friday morning the 10th is a close second for the glassy, long-period groundswell, even if it’s small. Get out there while it’s good.
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.
