The Lowdown
Alright crew, Rusty here. Let’s break down what’s in store for Joaquina over the next couple weeks.
The start of the week is where the magic is. Monday morning, August 24, is the one to circle – Joaquina gets a strong 6ft swell from the SSE with a 15-second period. That’s a lot of juice (1547 in combined energy) and with the wind glassy out of the SW at 3 mph, it’s going to be clean and powerful. This is for experienced surfers only – that size and long period will move fast.
Swell drops a bit by Tuesday the 25th, but it’s still a solid 4ft from the SSE with a 13-second period. Wind swings light offshore from the north, so expect glassy conditions again. Water temp is around 67°, about average for the time of year.
Wednesday the 26th brings a shift in direction – a consistent 5ft SE swell with that same long 15-second period, and moderate energy (1034). The wind stays cross-offshore out of the N, so clean surfaces all day – a quality session for anyone who knows the break.
After Thursday the 27th, the size drops quick. You’re looking at 3ft down to just 2ft through the end of August and into early September, with onshore winds from the S making things choppy and ugly. There’s a stretch of several days from Friday the 28th through Tuesday the 1st of September where conditions are straight-up poor.
Into the second week, there’s a flicker of hope. Tuesday morning September 8 shows a return of 5ft SE swell with glassy conditions, and by the afternoon a new 6ft SE groundswell with a very long 16-second period rolls in (energy climbing to 1580), but it comes with a light cross-shore breeze that could throw off the shape a little. That one’s worth watching, but it’s a long ways out.
No doubt about it – Monday and Tuesday mornings this week are the standouts. Solid, clean, and powerful for the crew who can handle it at Joaquina.
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.
