Sea Turtle Lighting Ordinance Guide

"Dark sky at night, turtle's delight!"

Many counties and cities along Florida’s coast have adopted sea turtle lighting ordinances. The intention of these ordinances is to protect Sea Turtles along the Florida coastline during the nesting season by restricting the amount of light permitted through windows and doors.

Hatching sea turtles are guided to move toward the water by the light of the moon. The artificial lighting of coastal construction is known to confuse the hatchlings.
