It’s that time of year when Florida’s beaches become a sandy birthing center for endangered sea turtles trying to eke out future survival.

Nesting season for green sea turtles generally runs from June through September along the state’s east coast. Leatherbacks, the state’s other protected species, nest from March to July and loggerheads from April to September.

Most greens will wait for nightfall to emerge from the ocean to come on shore, often nesting on beaches they’ve visited before. They will lay roughly 128 eggs three or more times during a season.

Last year, 409 green turtle nests were reported in Broward, 49 in Miami-Dade and 7,725 in Palm Beach, according to Florida Fish and Wildlife Conservation Commission statistics released in February.

Their enemies: illegal harvesting, habitat encroachment, fishing net entrapment and ingested plastic.

Lights from streets and homes can also distract newly hatched turtles away from the ocean. Most beachfront cities restrict lighting during turtle season.

The Florida phenomenon fascinates locals who typically fill up open spots at nighttime turtle walks, turtle hatchling releases and lectures.

Here’s a sampling of local events. Sea turtle sightings are not guaranteed and refunds are unavailable.
