What time does it start getting light on the island? by 6:30 am it is probably already quite light.
Aruba sunrise: 6:16 AM. Aruba sunset: 7:07 PM. (The closer to the Equator, the less seasonal variation in hours of daylight/ darkness. According to what I've read, the sun doesn't 'gradually' rise & set like most of us in higher latitudes are used to, but that it literally pops up and pops down).
That must be weird! So, ok, it is dayight at 6:30. Thanks. :)
