Life Cycle of Sea Turtles

Hey.

Can anyone tell me the exact (or at least narrow down) time between the Green Turtle/Hawksbill Turtle mate and lay their eggs and then the time before the hatchlings start coming out.

Green turtle - Wikipedia, the free encyclopedia
At around 45 to 75 days, the eggs hatch during the night and the hatchlings instinctively head directly into the water.

The incubation period is 64 days (Limpus 1995a).

The incubation period averages 60 days.

That's why I ask here if anyone can give me a more exact info. It's not very clear there... I thought maybe there could be someone here who was a bit of an expert.

By the way, Congrats to post number 600! Tada...

From the FAO SPECIES CATALOGUE, VOL. 11. SEA TURTLES OF THE WORLD, found at:

For the Hawksbill:

The duration of the incubation in days varies among separated nesting beaches and also along the season. It may last from 47 to 75 days, depending on the place and time.

For the Green sea turtle:

Egg incubation on the sand beach normally extends from 48 to 70 days; the duration of the incubation is related to temperature and humidity which change in the course of the season; hence it will be longer in cool weather conditions.

For the Eastern Pacific Green:

The incubation period varies with latitude and time of the season, from a minimum of 46 to a maximum of 62 days, in warm and cool weather respectively, commonly it is 50 to 55 days.
