The port of Pasacao is rich in stories on how it got its present name. Since the part is a bustling area, dockguards were stationed to maintain peace and order. These guards would usually shout "Pasa ikaw, Pasa ikaw" as instructions to passengers. This Spanish-Tagalog mixed up "pasa-ikaw" was mistaken by the passengers as the name of the place - Pasacao.
From February to May is hot and dry season in the Philippines and Pasacao in particular. From this months most visitors and tourists come to Pasacao to unwind. It is during the "Lingo ng Pagkabuhay" or the Easter Sunday that most resorts and beaches are fully loaded with visitors coming from nearby places and other areas of the world.
