The Lowdown
Alright, Rusty here again for the imperial crew.
Right off the bat, the first week is pretty quiet. Praia Grande is a beginner-friendly, exposed beach break that picks up swell mainly from the east. The water’s sitting at 66°F, which is basically what you’d expect for this time of year.
The first few days, from Sunday the 2nd through to Saturday the 8th, the swell is tiny, mostly around 2ft to 3ft, with a short 7-second period, so it’s weak and sloppy (combined energy in the 40s and 50s). There’s nothing to get amped about. The wind gives a few windows of clean conditions – Sunday the 2nd morning is a light offshore breeze that cleans it up, and a couple of glassy mornings on Monday the 3rd and Tuesday the 4th with the NNW breeze dropping off. But with that tiny swell, it’s just small, ordinary waves for a learner to mess around on. Not worth a drive.
Then Saturday the 8th afternoon sees a bump to 4ft from the southeast, combined energy hitting 156 (moderate), but the wind goes cross-onshore and the period is only 6 seconds – choppy and messy.
The real standout starts showing on Tuesday the 11th. Tuesday morning brings in a clean 4ft swell from the southeast with an 11-second period, offshore wind from the SSW at 6 mph, and combined energy at 351. That’s a solid, surfable groundswell with clean conditions. The longer period means longer waits between sets, but the wave shape will be much better. This is the first real highlight. The next day, Wednesday the 12th morning, is even cleaner with a 2ft southeast swell at 13 seconds and glassy wind, but size is back down.
Thursday the 13th morning looks good too – 3ft from the SSE at 12 seconds, offshore breeze, combined energy 277. Again, clean.
The biggest shout of the whole forecast is Saturday the 15th morning. We’re looking at 5ft from the southeast, 10-second period, offshore wind from the west at 6 mph, glassy clean, and the combined energy is 558 (strong). That is the best wave of the run. For a beginner spot, 5ft is getting proper, but for a decent surfer on a beach break, that’s a fun size with clean shape. The direction lines up nicely with the east swell window.
Then Sunday the 16th and Monday the 17th mornings both look decent – 4ft and 4ft from the east, with offshore and glassy winds, giving clean waves, but energy drops back to 234 and 268. Not the big one, but still good.
Best On Offer: Saturday the 15th morning for the biggest, cleanest swell of the period. Honourable mention: Tuesday the 11th morning for the first solid groundswell.
Rusty.

Information about the Praia Grande Surf forecast
The above surf forecast table for Praia Grande provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Grande can be found by selecting the local surf guide option on the grey menu. Our Praia Grande 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 (Praia Grande) 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 Praia Grande 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.
Praia Grande is 12 km (7 miles) from the city of Sao Francisco do Sul. If you plan a holiday in Santa Catarina - Norte, look for hotels and other accommodation in Sao Francisco do Sul. Sao Francisco do Sul has rooms for a wide range of budgets as well as car hire and transport links.
