Alright, let's get into it.

We've got Rosa on the radar. The water temp is sitting at 61°F, which is a solid 5°F colder than usual for this time of year. That's a notable chill, so you'll want a good wetsuit.

The first real action kicks off on the morning of Saturday the 4th of July. The swell is a solid 7ft from the south, with a nice long 12-second period pushing in some serious energy (2070). The wind is light and cross-offshore from the WSW, keeping things clean. This is for the experienced crew though – 7ft with that much punch isn't a beginner wave. It's the standout of the whole run.

Sunday morning on the 5th of July is another good look. Swell drops a touch to 6ft from the SSE, still an 11-second period, and the wind goes glassy from the NNE. That's about as clean as it gets. The energy is moderate (933), so there's plenty of push without it being too daunting.

The window tightens up after that. We get a few more chances, like the morning of Tuesday the 14th of July with 5ft from the SE and glassy conditions again, and the morning of Wednesday the 15th of July with a tiny 3ft swell but those glassy winds. The swell sizes are smaller, and the conditions aren't as consistent.

A couple of later calls show some potential. The morning of Friday the 17th of July has a 7ft swell from the ENE, but it's a short 7-second period and the wind is light cross, so it might be a bit lumpy. Then on the morning of Saturday the 18th, there's a 5ft SE swell, but again, tricky winds.

Overall, your best bet is that Saturday morning, the 4th of July. It's got the size, the period, and the wind. The early morning on the 5th of July is a close second for a bit more user-friendly size. There are gaps of a few days with nothing great, but that's how it goes sometimes.

Information about the Rosa Surf forecast

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

Rosa is 12 km (7 miles) from Imbituba. If you plan a holiday in Santa Catarina - Sul, look for hotels and other accommodation in Imbituba. Imbituba has rooms for a wide range of budgets as well as car hire and transport links.
