The Lowdown
G’day, Rusty here. Let’s cut to the chase—this stretch is going to be a real grind. The water’s sitting around 18°, which is a bit colder than normal for this time of year, so you’ll want the full rubber. For the next week and a half, Galheta is pretty much flat-out ugly. Small, weak swell, cross-onshore winds, and choppy, lumpy conditions. The combined energy barely gets going, mostly sitting in the low double or single digits—like 52, 15, 74—just weak, gutless stuff. Nothing worth paddling out for. There are a few moments of glassy conditions on the 17th and 18th, but the swell is still tiny, under 0.5m, with short 6-8 second periods. Not worth the effort. The 20th is a write-off with barely a ripple and energy at 4. That’s a long, flat gap from around the 13th through the 20th, nearly a full week of nothing.
Then things start to wake up. On Monday the 21st, we finally get some proper energy. The swell jumps to 2-1.6m from the ENE with a period around 8 seconds, and the combined energy climbs to 333-331—that’s moderate, solid push. The wind goes offshore and light, so it’s clean. Glassy morning on the 24th with 1.6m from the ESE, energy at 346, that’s the pick of the whole run, but it’s still just a 2 out of 10 on the overall quality because the period is short and the direction isn’t ideal. Galheta is exposed and prefers SSE swell, so we’re getting a bit of a side-angle thing here. Still, clean and chest-high is better than nothing.
The 25th holds at around 1.1m with offshore wind, clean but ordinary. By the 26th, it drops back to 0.8m, glassy morning, but again just ordinary. The 27th has a bit more push—0.9m with offshore wind and energy at 102, but the afternoon gets messy with cross-off conditions. Honestly, the standout window is the morning of the 24th—1.6m, ESE, glassy, clean lines, and moderate energy. That’s the one to circle. After that, it fades quickly, and the 28th is back to small, weak leftovers.
So here’s the deal: if you’re keen, the 24th morning is your best shot. Otherwise, this is a waiting game. The surf quality is poor for most of the forecast, with only a couple of brief windows where it’s surfable but very ordinary. The swell is there on the 21st and 24th, but the short period means it’ll be a bit soft and sectiony. It’s not a total blank, but it’s not a week to be picky. Keep your expectations low, and you might snag a few clean ones when the wind drops.
Rusty out.

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.
