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 Reef!
Located 1½ miles from the island of St. Croix, the 19,015–acre Buck Island Reef National Monument includes the 176-acre island consisting of tropical dry forest, and 18,839 acres of submerged lands and coral reefs. Proclaimed a national monument in 1961 by President John F. Kennedy, it was expanded in 2001 to preserve one of the Caribbean’s finest marine gardens. Endangered and threatened species live and nest here, including four species of sea turtles (hawksbill, green, leatherback, and loggerhead) and the St. Croix Ground Lizard. 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 "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.
