Radiation Point is located at the easternmost point of the island, near the massive Voice of America transmitting station, which you can spot by the large antennas. Before you head out, it’s a good idea to check in at the gate, though permission is usually refused. If you can’t get through, just paddle around and make your way to the point. This spot tends to be fairly consistent, catching both local southeast windswell and some south and southwest swells, making it a solid choice for a session.
The waves at Radiation Point are mostly right-handers and break over boulders. It works best with a south swell direction and can handle swell sizes starting at around 2 feet (0.6 meters). You're likely to enjoy it more when the wind is coming from the west, which is cross-offshore for the biggest waves. Keep in mind that when the tide gets too high, the waves can become fat and inconsistent, so it's better to surf during low to mid tides. This spot is suitable for intermediate surfers, offering a chance to work on your skills.
As for the surrounding area, from Radiation Point to Porto Alegre, there are several right pointbreaks, but they usually need a decent swell to get rolling. If you find the conditions off at Radiation Point, you might want to explore a bit down the coast for other options.
