Use the early window and let thunder set the schedule.

Start with a flexible morning beach window, carry water and plan a shaded or air-conditioned stop during the hottest stretch. At the first sound of thunder, leave the water and beach immediately and wait for official guidance before returning.

Keep the island loop easy when skies change.

Siesta Free Ride can connect the beach, Village, restaurants and your hotel without another parking search, so your group can pivot easily when a shower moves through.
