Best Time to Visit Aruba for Warm Weather
Aruba is warm year-round with very little temperature fluctuation due to its location in the southern Caribbean near the equator.
Despite the relatively stable climate in Aruba, there are some fluctuations in temperature throughout the year. The months of January and December are slightly cooler than the rest of the year, with high temperatures averaging around 85°F (29°C) and 86°F (30°C), respectively. The hottest months are August and September, with high temperatures averaging around 90°F (32°C). May, June, July, and October also have high temperatures of 89°F (32°C).
These fluctuations in temperature can be attributed to a few factors, such as changes in ocean currents and winds. Aruba is located in a region where the trade winds blow from the east, which helps to regulate the island’s temperature and prevent it from becoming too hot. However, changes in wind patterns can cause fluctuations in temperature, and changes in ocean currents can also affect the island’s climate.
You’ll also want to consider humidity, which can be extreme in Aruba. The muggiest months in Aruba are May through early December (source), with August, September, and early October usually being the worst.

If you want to maximize daylight hours, you will want to visit the island between the months of March and September.

Best Time to Visit Aruba to Avoid Rainy Weather
The climate in Aruba is hot, semi-arid and is characterized by dry, sunny weather with very little rainfall. Even the rainy season doesn’t get as much rain as other Caribbean islands. Out of roughly 700 islands in the Caribbean, Aruba consistently ranks as having the least amount of rainfall (Aruba averages approximately 15 inches of rain for the entire year).
The lack of rainfall is due to its location outside of the hurricane belt, as well as the island’s arid topography, which results in little moisture being retained.
Despite its location near the equator, Aruba does experience a “rainy season”, which typically occurs between October and January. During this time, the island receives slightly more rainfall than other months, but it is still relatively low compared to other Caribbean islands.
During rainy season, it is probably best to pack a jacket for Aruba. March through August is the best time to visit Aruba if you want to avoid rain.

Best Time to Visit Aruba to Avoid Windy Weather
Aruba is windy most of the year due to strong trade winds. September through December have less wind than other months on Aruba.
Aruba’s location in the path of the trade winds means that there is a constant flow of air moving from east to west across the island. These trade winds are created by differences in air pressure between the equator and the Earth’s poles.
The winds are further amplified by the geography of Aruba, which is relatively flat and lacks tall mountains or other natural features that might block or deflect the wind. This means that the winds can move relatively unimpeded across the island, leading to consistently windy conditions.
Additionally, the ocean surrounding Aruba contributes to the island’s climate. The nearby waters are relatively warm, and this creates a thermal gradient between the ocean and the land. This gradient causes air to rise over the island, which can create even stronger winds as cooler air from over the ocean rushes in to replace the rising air.
Overall, the combination of the island’s location in the path of the trade winds, its relatively flat geography, and the thermal gradient created by the warm ocean waters all contribute to Aruba’s consistently windy climate.
Many people actually enjoy the wind in Aruba because it brings relief on hot, humid days, and creates a nice breeze at night. You can usually find relief near large hotels and other structures that act as wind barriers (types of resorts in Aruba).
