Pinellas beaches enter nesting months with a simple ask – keep them dark, clean and flat.
During spring, sea turtle nesting season is underway in Pinellas County, marking the start of a six-month stretch when one of the area’s oldest natural rituals plays out after dark on local beaches. County officials say nesting and hatching run from May 1 through Oct. 31, and that the loggerhead is the species most commonly found nesting in Pinellas. All seven sea turtle species are listed as threatened or endangered.
For beach towns from St. Pete Beach north through Clearwater, that makes early summer more than tourism season. It is also the period when female turtles come ashore at night, dig nests with their rear flippers and lay 100 to 150 eggs at a time. A single female may lay three to eight nests in one season. After roughly 45 to 70 days, hatchlings emerge and instinctively head toward the brightest natural horizon – traditionally the moonlight and starlight reflecting off the water. County guidance says only about one in 1,000 hatchlings survives to adulthood, which is why even small disruptions matter.
The biggest human-made problem is light. Pinellas County warns that bright lights and illuminated objects visible from the beach can disorient hatchlings, drawing them inland instead of toward the Gulf. Florida wildlife officials say artificial lighting can also discourage nesting females from coming ashore at all, or push them toward less suitable nesting spots. In a county defined by condos, hotels, roadways and late-night beach activity, that makes lighting one of the most consequential issues of the season.
That is why the seasonal message for residents, renters and visitors is so direct: keep it low, keep it long, keep it shielded. Under Pinellas County and Florida Fish and Wildlife guidance, beachfront lighting should be mounted low, aimed downward and shielded from the beach, while bulbs should use long-wavelength light in the amber, orange or red range. The county also advises property occupants to turn off lights visible from the beach after sunset and use approved amber lighting when light is necessary. Florida Fish and Wildlife says the preferred standard is light at 560 nanometers or greater, with unnecessary decorative lighting shut off entirely.
The rules are not just suggestions in many places. Pinellas County says 12 of its 13 barrier-island municipalities have lighting ordinances intended to help hatchlings find their way to the water. On St. Pete Beach, city guidance also tells beachgoers not to shine lights at turtles, not to use flash photography around them, and never to interfere with marked nests, which are protected under state law.
Beyond lighting, the public’s role is remarkably practical. St. Pete Beach promotes the phrase “Clean, Dark, Flat” as the easiest way to remember what helps most. “Clean” means removing trash, food waste, toys and gear. “Dark” means avoiding artificial light on the beach at night. “Flat” means filling in holes and knocking down sandcastles before leaving. Those small obstacles can trap hatchlings or block nesting females, and county officials similarly urge beachgoers to pick up trash and cover holes to create a clear path to the water.
Monitoring the season is a countywide effort. In north Pinellas, Clearwater Marine Aquarium says it begins patrols on April 15 and monitors about 21 miles of beach, with staff, interns and volunteers searching just before sunrise for tracks, nests and false crawls. In the southern part of the county, Sea Turtle Trackers says its volunteers patrol St. Pete Beach, Shell Key and Outback Key every day from May through October, marking and protecting new nests and responding year-round to stranded turtles. Together, those patrols form the quiet, early-morning backbone of local sea turtle protection.
Pinellas County notes that it recorded a record 669 sea turtle nests in 2019, though officials say nesting numbers have declined since then, making each nest more significant. The broader outlook can also be shaped by storms and beach conditions. Clearwater Marine Aquarium reported that along the beaches it monitors, the 2024 season produced 271 nests, up from 227 in 2023, but many active nests were later washed out by hurricanes. That mix of resilience and vulnerability is exactly why local officials return to the same message every spring: protecting sea turtles is not abstract conservation policy, but a set of nightly decisions made by the people who live near the beach and the people who visit it.
For anyone who encounters a turtle, hatchling or disturbed nest, the guidance is simple: keep your distance, do not touch, and report injured, stranded or harassed animals to the FWC Wildlife Alert Hotline at 888-404-3922. In a place that markets its sunsets and shoreline as everyday pleasures, sea turtle season is a reminder that the beach belongs to more than the people on it. For the next several months, a darker, cleaner, flatter beach could mean the difference between a lost hatchling and one that makes it home.www.pinellas.gov/sea-turtle-protection
