Compared to May, the warmest months are June through November, when daytime temperatures can rise to more than 90 degrees Fahrenheit or about 33 Celsius. The heat is especially noticeable in the island’s interior. Beach sand will sometimes feel uncomfortably hot on bare feet, as we found out from our summertime visits there.

The coolest months are January through March, when highs even out at around 79 degrees Fahrenheit.

Because of the arid and desert climate of Aruba, temperatures vary throughout the day. They are likely to be coolest at nighttime.

The ever-present trade winds in Aruba help to make even the warmest temperatures feel more comfortable.

Aruba has little humidity throughout the year. The heat, therefore, is a dry heat, making the air feel less unpleasant.

Sea temperatures remain fairly consistent throughout the year, usually staying between 79 degrees and 83 degrees Fahrenheit. There are exceptions; the water was too chilly for swimming for us and other people during a February visit.

Aruba has little rainfall throughout the year. The amount of rainfall increases during hurricane season, and Aruba receives the most rainfall between October and December.
