Rock the Ocean's annual Tortuga Music Festival returns to Fort Lauderdale Beach this weekend with a three-day event featuring performances from country and rock artists such as Post Malone, Riley Green and Kenny Chesney. The festival partners with the Rock the Ocean foundation to raise awareness about marine conservation efforts. It has raised over $6 million through ticket sales and donations to support scientific research, education, and ocean conservation initiatives. Officials are urging festival attendees to stay hydrated throughout the festival and report any suspicious activity.
