Sea Turtle Nesting Season

Sea Turtle By Sarosh Jacob

Three species of sea turtles typically nest on Broward’s beaches each season: leatherbacks (Dermochelys coriacea), loggerheads (Caretta caretta), and green turtles (Chelonia mydas). 

Adult females emerge from the ocean at night to lay their nests and use natural light from the moon and stars to orient back to the water. Unfortunately, artificial lighting near the beach can disrupt this sea-finding process and cause turtles to become disoriented. To reduce the amount of artificial lighting reaching the beach in Broward, local coastal municipalities enforce lighting ordinances during sea turtle nesting season (March 1 - Oct. 31).

Lighting near the beach should be “sea turtle-friendly” and follow all three criteria below, established by the Florida Fish and Wildlife Conservation Commission:

Keep it low: Fixtures should be mounted as low as possible to achieve their purpose. Fixtures/bulbs should produce the lowest lumens (light) necessary for the task.

Keep it shielded: The bulb, lamp or glowing lens should be shielded from the beach. This includes interior lights. Curtains and shades can be closed after sunset.

Keep it long: (wavelength) Fixtures/bulbs must produce long wavelength light (560 nm or longer) without filters, gels, or lenses. Amber and red LEDs are good examples of these types of light.

The Florida Fish and Wildlife Conservation Commission provides a list of certified fixtures that meet all three criteria listed above.

Alternatively, you can contact the County for assistance with light retrofitting or additional information.
