Why does... How does... Will it...?

Yes! Puerto Rico is closer to the equator in the Caribbean, so our sun sets year round between 6:30pm and 7:15pm. We adjust the first tour’s check in time accordingly for those seasonal changes. By the time you are on the shoreline, it is dark and the water is glowing.

If you are a sciency type, check out the explanation and diagram about how the earth’s orbit affects daylight on the Conversation website.

Short answer: No!

Long answer: Due to the moon rising an hour later every day, there are two weeks of no moon light (excellent biobay viewing), one week of minimal moon light (very good biobay viewing) and one week of a fair amount of moonlight leading up to the full moon (reflecting moonlight makes it harder, but the bay still glows and we will take you to the best spots to enjoy it).

Don’t let the lunar cycle stress you out. Whenever you are in Vieques is a great time to visit the biobay… except during the full moon closures: the day before, the of and the day after the full moon. 

The Puerto Rico Department of Natural and Environmental Resources manages Vieques’s biobay. DNER closes the bay for three nights every month around the full moon for conservation purposes. Give us a call if you are unsure of when to schedule your visit to Vieques.
