Imposivel is a surf spot located to the north of Barra da Sirinhaem, right off the coast of Ilha Santo Aleixo. It's a bit tricky to get to, as it's only accessible by boat. This spot is known for its mysto lefts, which can be hard to find and require some effort to reach. The area can often feel isolated, making it a unique place for experienced surfers looking for a challenge.

The waves at Imposivel work best with a southeast swell, but you can also catch decent waves with swells coming from the east and south. This spot handles swell sizes around 4 feet (about 1.2 meters), breaking over an uneven reef. The ideal conditions are on a high tide with a bit of north wind, creating left-breaking waves ideal for those who are at an expert level. Make sure you are up for it, as the spot can be demanding, especially with its reef setup.

Since Imposivel is only accessible by boat, be sure to plan your trip accordingly. The surf can get pretty epic out here, but it helps to be prepared for some sharky waters, so stay alert while you're out there. This isn’t a spot for beginners, so if you're thinking about hitting Imposivel, make sure you’re ready for some serious surfing.
