Despite the fast-flowing water currents at certain times of the year, the diving destinations in this region are some of the best in Bali.
This section lists the top sites around Lembongan Island with further information about the unique marine life that exists in the area.
Three islands attract scuba divers and snorkelers to this area:
The archipelago straddles the Badung Strait (e.g. where the tidal shift shoots past Bali's south eastern coastline).
As a result, the cold upwelling currents that rise from the Indian Ocean tend to keep the water clear - but a little chilly.
In fact, the water clarity found at the north western dive spots of Nusa Lembongan and Nusa Penida is the primary reason why local dive shops rate them as some of the best diving in Bali, Indonesia.
You should expect to have underwater visibility ranging from 15 to 20 metres for most of the year, especially at the deep water sites.
In general, the water temperature stays around 27° Celsius for most of the year. But, it drops to the low twenties from July through to September. So, these are the best months to see the gigantic Mola Mola (ocean sunfish).
Diving at the southernmost sites offers the best opportunities for swimming with the majestic manta rays as they swirl above.
The underwater topography in this part of the Nusa islands is relatively sparse with large plateaus. In other words, you will find many cleaning and feeding stations that are a favourite meeting place for mantas.
Besides the usual ravines and swim-throughs, the diversity of the marine ecosystems also create natural habitats for coral formations and incredible sea life. For example, some of the lesser-known species include:
It's fair to say there is no clear winner for whether Nusa Lembongan or Penida is better for diving. But, this list will help you find the best dive site in Nusa Lembongan for beginners as well as for divers with a lot of experience:
Pro Tip: All divers and snorkelers should have a surface signaling device to show their position in the water to any passing boats.
