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 (<answer>1,420</answer> 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.
