Average high temperatures range between 84°Fahrenheit (F) and 89°F, and lows between 73°F and 80°F (23°C to 27°C). Low temperatures in the winter rarely dip below 73°F (23°C). Between April and June there is typically little rainfall. Hurricane season is officially June 1 through November 30, with peak months for storms between August and October.

The strong Easterlies can sometimes bring clouds of African dust from the Sahara; millions of tons of dust can be transported each year, affecting air quality, and potentially affecting marine life, including coral reefs.

Welcome to Buck Island!

Located 1½ miles from the island of St. Croix, Buck Island Reef National Monument includes over 19,00 acres of both submerged and dry lands. On land, trails will take you through our tropical dry forests, manchineel beach forest, pristine sand beaches, and rocky shores. In 2001, our park was made the first Marine Protected Area, providing protection for all park resources from the island's highest peak to 5,000 feet below the water. Our beaches are home to several endangered and threatened species, such as hawksbill, green, leatherback, and loggerhead sea turtles, and the St. Croix Ground Lizard. Every summer, least terns arrive to nest, followed by pelicans in the fall. Elkhorn coral, the first listed marine invertebrate, surrounds two-thirds of the island. Elkhorn coral patch reefs rise up nearly 40 feet to the surface. Prehistoric peoples canoed from the "mainland" of St. Croix and camped on the beach, where they fished and gathered sea turtle eggs, bird eggs, and conch. In the 1700s and 1800s, the Danish government established a signal station on the island’s highest peak, at 328 feet (100 meters). A signal keeper, his family, and enslaved workers lived nearby.
