December to April: the sweet spot

Dry season brings sunny days, calm seas, and excellent snorkel visibility. This is peak season, so book ahead since tours fill up.

May and June: great and quieter

Good conditions with fewer crowds and slightly lower prices. An underrated window for Cayo Icacos.

July and August: warm but variable

Warm with mostly good days, though occasional swells can stir up visibility. Mornings are calmest, so book early sailings.

September and October: hurricane season

Peak Atlantic hurricane season. Tours can be cancelled at short notice and seas are less predictable. Build in buffer days and book refundable tours.

November: shoulder bonus

Conditions settle again with returning clarity and fewer crowds before December. A quietly excellent month.
