The Lowdown
Alright surfers, Rusty here. Let’s break down what’s happening at Joaquina over the next couple of weeks. The short version is we’ve got a quiet start, but there’s a killer session coming up at the end of July that’s got me stoked.
The first week is pretty flat. From Friday the 17th through the early part of the following week, the swell is tiny and weak. The combined energy readings are mostly in the single and double digits, so there’s not much to chase. It’s a real lull, so save your energy.
We get a little pulse on Wednesday the 22nd. Swell is a tiny 2ft from the SSE, period around 8 seconds. The morning is glassy, which is a nice sight, but the energy is still low (combined energy of 51). It’s surfable, but nothing special. Thursday the 23rd afternoon sees a bump to 4ft from the SSE, with the combined energy hitting 344, but it’s still rated as marginal.
Now, things start looking up for the weekend. Saturday the 25th is looking nice. We’ve got a solid 4ft swell from the SE, with the period stretching to 10-13 seconds, bringing some real groundswell punch. The wind is light and variable, going glassy in the afternoon. The combined energy sits at 350-426. This is clean, fun-size surf. Not the biggest, but with those offshore/glassy conditions, it’ll be a sweet session.
But the real standout, the one you need to plan for, is Wednesday the 29th of July. Wednesday afternoon delivers a beautiful 5ft swell from the SSE, with a period of 12 seconds. That’s a proper groundswell. The combined energy jumps to a massive 1012, so there’s plenty of power. And the wind? It goes glassy. This is the kind of session that makes you call in sick. The swell is over 5ft, so it’s getting a bit heavy for beginners, but for the experienced surfers, it’s prime time. The swell direction is a good match for the SE optimum, and with the light wind, expect smooth, clean faces.
Keep in mind this spot is a sandbar, and very consistent, so it’s usually got a bank. The downside? It can get crowded and often is, so be ready to share the lineup. The water temp is about average for this time of year, so a 3/2 wetsuit is probably the call.
There’s a window a couple days later, on Friday the 31st of July, with a bigger 7ft swell from the SE, but it’s predicted to be too big for the break, geared more for experts. The energy is enormous (1705 in the morning), but for your average surfer, that’s a day to watch from the beach.
So, to wrap it up: the first week is a gap with no real surf. The standout session is Wednesday afternoon the 29th of July. Saturday the 25th is a solid second option for a cleaner, smaller wave. Get on it if you can.
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.
