Nusa Penida is a large island located in the southeast of Bali, across the Badung Strait. To the northwest lie two smaller flatter islands, Nusa Ceningan and Nusa Lembongan. There are some dive operators on Lembongan and the islands can be reached by dive boat in approx. an hour from Sanur or Padang Bai. Most dives sites are to the north around Lembongan and Nusa Penida and in the channel between Ceningan and Nusa Penida. Currents can be really strong around these islands because they lie smack in the path of the Indonesian Through flow. The Lombok Strait separates the Indonesian islands Bali and Lombok and is the second most important strait through which water is exchanged between the Pacific Ocean and the Indian Ocean.
Why is it so cold? Temperatures are around 26-ªC but depending on the currents it can be a chilling 15 or 20-ªC. This cold water comes from an area north of Nusa Penida where it is very deep (1300m). Nusa Penida is a large barrier to the currents coming from the north and produces strong upwellings – that’s the cold water pressed upwards. The cold water makes for relatively good visibility though.
Lembongan island Lembongan island has shallow areas where there are seaweed farms and mangrove forests. Blue Corner (Ental Point): Ceningan Channel Nusa Penida Nusa Penida This island also accessible by traditional boat, called jukung from Padang Bai, Candi Dasa and Kusamba. Toyapakeh lies on Nusa Penida’s northwest point, in Ceningan Channel, close to the pontoons where the tourist ships moor. Gamat Bay is a small bay located between Toyapakeh and Crystal Bay. Crystal Bay (Penida Bay) Ceningan Point (also called Ceningan wall) lies at the northern tip of Ceningan island. Malibu Point is on the east coast of Nusa Penida, outside Suana village. Manta Point (Batu Lumbung) Batu Meling and Batu Abah: Batu means “rock”. Nusa Dua, Sanur and Benoa There are some fringing reefs along Serangan island and the coast of Nusa Dua, but visibility is usually not very good due to the closeness of Benoa harbor (Teluk Benoa).
