Compared to most Caribbean destinations, almost anytime is a good time to go to Aruba.
Many vacationers try to avoid the Caribbean's annual hurricane season, which runs from June 1 to November 30. The island of Aruba, located 15 miles off the coast of Venezuela, is located just south of the hurricane belt.
Aruba is part of the ABC islands of Aruba, Bonaire and Curacao that are known as attractive Caribbean vacation destinations because they usually see few effects from the hurricanes and tropical storms that pass through the rest of the region. However, the island does run the risk of a rare hurricane passing nearby, such as Omar in October 2008.
The average monthly high temperature is nearly 89 degrees Fahrenheit, according to the Meteorological Service of Netherland Antilles and Aruba. That makes Aruba one of the warmest destinations in the Caribbean. The average monthly low temperature is 78 degrees.
As a result, the water temperature averages 81 degrees during the year and rarely varies more than a few degrees.
Rainfall is exceptionally low on Aruba -- only 16 inches in total for the year and less than 1.4 inches per month.
Best and Worst Months
Caribbean weather is known for its warmth, but Aruba is warmer than most because of its close location to the equator.
Average high monthly temperatures exceed 90 degrees in August and September and drop to a low of 86 in January and February.
Rain totals about 2.5 inches in October and December and exceeds three inches in November.
Anyone wanting to get ideal conditions for visiting Aruba should consider January through July as good times to go. The higher temperatures in August and September will make shopping, hiking and other outdoor activities more uncomfortable.
October through December are less than ideal because of higher rainfall and the rare possibility of a hurricane or tropical storm. But the risk of a hurricane is low enough and the rainfall is moderate enough compared to the rest of the Caribbean that vacationers will still face favorable odds with the weather.
