The Lowdown
Alright folks, Rusty here. Let’s have a look at what the ocean’s got cookin’ for us over the next couple of weeks.
Right off the bat, we’ve got a real flat spell. Don’t even bother waxing the board for the first few days. The 11th through the 14th are basically a write-off with tiny, weak energy and onshore junk.
Things start to stir around Tuesday the 15th. We get a pulse of easterly swell pushing 6 ft, with moderate wave energy (574). The problem is the wind is mostly cross or cross-on, keeping things a bit lumpy. Not the day to call in sick for.
Wednesday the 16th and Thursday the 17th see that same swell drop off and get chopped up by onshores again. We’ve got a bit of a waiting game.
Now, here’s where it gets interesting. The real window opens on Sunday the 20th. The wind swings around to the north-northeast, giving us a clean cross-off at Galheta. We’re looking at waves around 3 ft to 4 ft from the east, with solid energy (222). It’s not huge, but it’ll be clean and fun for an intermediate.
But the standout, the one I'm circling on the calendar, is Monday the 21st of September. Glassy conditions in the morning. The wind is dead calm from the north, 3 mph. The swell holds at 4 ft from the east. That is as good as it gets for a clean, user-friendly session. The wave energy is pumping at 322. The swell period is short (7 seconds), so it won’t be a big, powerful groundswell, but the clean conditions will make up for it. That morning session is your best bet. After that, the wind goes easterly and messes it up.
After Monday, things quieten down again. We get a few small, clean days around the 23rd and 24th, but the swell drops right off. By the 26th, we’re back to tiny 1 ft leftovers, so don’t plan a trip around the second weekend.
Bottom line: this forecast starts flat, builds to a small but very clean window around the 20th and 21st, with Monday the 21st morning being the undeniable highlight. After that, it fades away.
Rusty.

Information about the Galheta Surf forecast
The above surf forecast table for Galheta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Galheta can be found by selecting the local surf guide option on the grey menu. Our Galheta 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 (Galheta) 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 Galheta 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.
Galheta 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.
