"South Florida's Swimmers Face Deadly Marine Heat Wave Threatening Coral Reefs"

Swimmers in South Florida are braving record-high ocean temperatures, with water reaching up to 92.5 degrees Fahrenheit off the coast of Virginia Key. The scorching heat has led to 16 consecutive days with a heat index at or above 105 degrees in Miami, prompting the National Weather Service to issue an extreme heat advisory. Despite the hot water, beachgoers are undeterred, enjoying the warm ocean that feels like a "thick, simmering syrup." The unusually warm temperatures have also resulted in pristine beaches and sightings of manatees and sharks.
