Saint Lucia is an island country in the eastern Caribbean Sea on the boundary with the Atlantic Ocean. Part of the Lesser Antilles, it is located north/northeast of the island of Saint Vincent, northwest of Barbados and south of Martinique.
Expect hot and humid weather conditions year round due to the island's proximity to the equator. Fortunately, visitors will rarely feel uncomfortable as mild trade winds bring cool breezes off the water that offer some respite from the heat.
St. Lucia temperature ranges from 70 degrees Fahrenheit to the upper 90s. Humidity on the island averages between 70 and 90 percent throughout the year. December through January are generally the coolest months with the temperatures being in the mid 70s to mid 80s. The summer months of June through August are the hottest in St. Lucia where temperatures in the mid to upper 90s are not uncommon.
