The Lowdown
Alright, let me break it down for you, mate. It’s Rusty, and I’m looking at Joaquina for the next couple of weeks.
Honestly, the first few days are a total bust. The swell is barely there – 0.3ft to 1ft waves with hardly any energy. The water is sitting at 61°, and that’s 5° colder than it should be this time of year, so it’s gonna be a chilly paddle. The wind is blowing cross-off from the north, and it’s just flat. This dry spell runs right through the end of the week.
We finally get a little bump on the 22nd of July. Wednesday morning shows 2ft of swell from the SSE with a 8-second period, and the wind goes glassy. The combined energy is still weak, about 59. It’s rideable, but nothing to write home about. That glassy patch is the best of a pretty average start.
The one you need to mark on your calendar is the morning of the 27th of July. I know it’s a week out, but this is the pick of the forecast. The swell comes up to 4ft from the east, the wind goes offshore from the NNW, and it’s clean. The combined energy is 251 (moderate), so there’s some punch. The ideal direction for Joaquina is SE, so this east swell is a bit angled, but with offshore wind, it’ll still be a fun morning. The break is a sandbar, very consistent, so you’ll get waves. That’s the best session.
The 30th of July is another good one. Thursday morning is glassy again with a 3ft SSE swell and a combined energy of 285. That’s another clean, solid morning. By the 31st of July, we get a bigger pulse – 6ft from the east, but the period drops to 8 seconds and the wind gets stronger from the NNW. That’s getting into the size where it’s not for beginners, and the cross-off wind will make it a bit rough. Still, for the experienced crew, it’s got some serious energy (672).
So yeah, it’s a slow start, but the last week of July shapes up nicely. The 27th morning is the winner – offshore wind, clean, and a solid chest-high wave. Don’t miss the 30th either. Get after it.
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.
