There is no wrong time to visit Aruba. Unlike much of the Caribbean region, Aruba has a dry climate and an arid, cactus-strewn landscape. Cooling trade winds help to keep temperatures consistently mild, averaging around 28°C (82° F) almost all year round. The average rainfall is less than 50 cm (20 inches) a year, occurring mainly in short showers during November and December. Aruba is located safely away from the traditional path of hurricanes.
January, February and March are the most popular times to visit. During Carnival, just before Lent, the island is hopping with parades, festivities and parties. Mostly the Americans from the east coast fleeing winter make Aruba the most touristed of the Netherlands Antilles. If you prefer smaller crowds and a more relaxed atmosphere, plan your trip for mid-April through September.
