The wet season begins some time in May, ending in mid-October. During this period, temperatures are in the mid 80s to low 90s (29–35 °C), accompanied by high humidity, though the heat is often relieved by afternoon thunderstorms or a sea breeze that develops off the Atlantic Ocean, which then allow lower temperatures, but conditions still remain very muggy. Much of the year's 55.9 inches (1,420 mm) of rainfall occurs during this period. Dewpoints in the warm months range from 71.9 °F (22.2 °C) in June to 73.7 °F (23.2 °C) in August.
