Weather, Climate & Forecast

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.

Temperature

The temperature on Aruba is measured in Celsius and is practically constant throughout the year. On average the temperature varies between the 26 and 32 degrees Celsius.
Most hotels also communicate the temperature in Fahrenheit and since the electrical current is the same as in the US (110V/60Hz), most air conditioning systems in Aruba are manufactured for the US market and therefore also show degrees in Fahrenheit. Here is a convenient conversion table:

Celsius 22 26 30 32 38
Fahrenheit 70 80 86 90 100

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.
