Aruba features a hot, tropical savanna climate (Köppen Aw) with minimal seasonal variation, making it ideal for year-round residency. Daytime temperatures consistently range from 30-33°C, with nights at 24-26°C, accompanied by trade winds that moderate the heat. Annual rainfall is very low at around 400-500mm, mostly during brief October-December showers, while the dry season spans February-May. High sunshine hours exceed 3000 annually, with sea temperatures always above 26°C perfect for water activities. Low hurricane risk south of main paths appeals to expats seeking reliable warmth, though high humidity and winds require adaptation for comfort.
