Miami Beach, FL Outdoor Lighting: Dark Sky Rules (2026)

Miami Beach is a nesting ground for three protected sea turtle species: Loggerhead, Green, and Leatherback. Chapter 46, Article V of the City Code establishes the Turtle Nesting Protection Ordinance, originally adopted in 2006 and significantly strengthened in October 2024. The updated ordinance expands requirements beyond exterior lighting to include interior lights in hotels and commercial properties that are visible from the beach. During nesting season from April 1 through October 31, all exterior lighting visible from the beach must be either turned off, shielded to prevent light from reaching the beach, or use turtle-safe amber or red wavelength lighting (590nm or longer). The city's guidance is to keep lights low, long-wavelength, and shielded. Properties within the regulated zone must retrofit non-compliant fixtures. The nesting season begins April 1 to account for the earlier Leatherback nesting period. Light pollution disorients nesting adults and hatchlings, which instinctively navigate toward the brightest horizon, mistaking artificial light for the ocean's reflection of the night sky. The city runs a Flip the Switch awareness campaign and hosts an annual Turtle Fest educational event.
