Weather Forecast and Climate information
Aruba is situated 12 degrees 30' north of the equator. The weather is tropical but not extreme, with a median and fairly constant temperature of 82 degrees Fahrenheit (28 degrees Celsius).
It is important to mention that Aruba lies south of the general hurricane paths and usually only experiences fringe effects of nearby tropical weather. Nonetheless it is not unknown that tropical systems forms close by and do have their effects on the ABC islands (Aruba, Bonaire, Curacao).
Trade winds cool the island, making lying in the sun on one of the many beaches much more tolerable although care should be taken since this is deceptive - the sun is strong, in particular between 11am and 2:30pm and the use of high-SPF sunscreens is strongly recommended especially for fairer-skinned people.

What to wear
With Aruba's tropical climate, you will be comfortable in casual summer wear plus some light evening wear for restaurants, nightclubs and casinos (men might need a light jacket for some of these). Shorts and slacks can be worn on the streets of Oranjestad. Bikinis should preferably be reserved for beaches and swimming pools and are not permitted in shopping and business areas. No real need for elegant evening wear, casual silk or linen dresses & slacks will do. A light sweater for the cooler evenings might come in handy.
