Sea turtle nesting season generally runs from spring through early fall, with most U.S. nesting beaches seeing activity between March and October, and a strong peak from about May to July.

When is sea turtle nesting season?

For most warm‑water coasts where sea turtles nest, the pattern looks like this:

  • Overall season window: Roughly March through October on many Florida and Southeast U.S. beaches.
  • Peak nesting months: Often May, June, and July, when the highest number of females come ashore to lay eggs.
  • Example – Florida Atlantic coast:
    • Some areas “officially” mark nesting season as May 1 through October 31.
* In Southeast Florida (e.g., Boca Raton to Hutchinson Island), nesting is typically **March through October** , peaking **May–July**.
  • First nests: Many monitoring programs report their first nests in early to mid‑May , with nesting females continuing into mid‑August in some locations.

Because sea turtles nest in warm climates worldwide, exact timing varies slightly by region, but if you are on a U.S. Atlantic or Gulf beach, “sea turtle nesting season” almost always means the late spring to early fall months, centered on late spring and early summer.

Quick tips if you’re visiting during nesting season

  • Avoid bright lights on the beach at night so hatchlings can orient to the ocean.
  • Don’t disturb marked nests or crawl tracks in the sand. Many areas stake or tape them off to protect eggs.
  • Fill in holes and smooth out sandcastles before you leave so nesting females and hatchlings don’t get trapped.
  • If you want to see nesting safely, look for guided, permitted “turtle walks” offered by local nature centers or refuges.

TL;DR: If you’re planning around sea turtle nesting, think late spring through early fall , with May–July as the heart of the season on many popular nesting beaches.
