Climate is warm humid with storms and strong winds and rainfall during July-October, and a prolonged dry period from November to July (Alvarado and Huacuz, 1996). Major hurricane and tropical storm activity prevails during June to November in the Eastern North Pacific (NHC, 2013). The black sea-turtle breeding season coincides from August to March, with the hurricane and tropical storm activity, which suggests that morphologic changes along-beach and on the beach profile occur seasonally. Two zones are favored for turtle nesting: the middle zone of the beach profile, around100 m from the beach tide front, and alongshore on the western and central sectors of Colola beach (Fuentes et al., 2010).
