The Best Time of Year to Dive in Bali

Bali's Diving Seasons Explained

Bali has two main seasons: the dry season (April to October) and the rainy season (November to March). Both offer great diving, but with subtle differences.

The dry season is generally considered the best time to dive. During this period, the seas are calmer, visibility can reach up to 30 meters, and there's less rainfall to stir up sediment. It's also when sites like Nusa Penida shine, thanks to stable currents and excellent conditions for spotting pelagics.

The rainy season, on the other hand, brings fewer tourists and more lush landscapes above water. While rainfall is higher, many dive sites remain accessible and vibrant especially along Bali's east coast, where conditions are often sheltered.

Planning Around Marine Life

One of Bali's main attractions for divers is its seasonal marine visitors.

From July to October, you're more likely to spot the elusive mola mola (oceanic sunfish) around Nusa Penida. These deep-water giants rise to shallower depths when the water gets colder, offering a rare and thrilling encounter.

Manta rays, however, can be seen year-round, especially at Manta Point, a site known for its cleaning stations and resident ray population.

Macro lovers looking for ghost pipefish, nudibranchs, or frogfish will find Bali's muck dive sites productive no matter the season particularly around Tulamben and Seraya.

Water Temperature and Visibility

Water temperatures in Bali range from 26°C to 29°C, but may drop to 22°C at deeper sites during July to September especially around Nusa Penida. This makes a 3mm wetsuit suitable most of the year, though some divers prefer a thicker suit in cooler months.

Visibility is often best between May and September, especially in open ocean sites. If photography is on your agenda, this window is ideal.

Crowds and Conditions

July and August are peak tourist months in Bali. While the diving is fantastic, popular sites can get crowded both on land and underwater. If you're seeking a quieter experience, consider visiting in May, June, or September you'll still catch great visibility without the heavy crowds.

For those who prefer personalized attention, booking through a well-established scuba diving center in Bali ensures guided dives with local insight, no matter the season.
