Bali Diving Season is unique but most importantly is that Bali provides friendly conditions for both beginner and advanced divers as well as Discover Scuba Diving / Try Diving.
There are several factors that could influence the bali diving season but primarily it’s the Bali moon cycle than the weather. For Neptune Scuba Diving, rarely it happens that we cancel a trip due to the weather but it does happen that sometimes the Bali moon cycle will create surges and underwater currents that are difficult to manage.
Here’s what you need to know about the Bali Diving Season and Bali Moon Cycle
High and low tides are particularly pronounced when the sun and moon are in alignment. Drift diving can be particularly difficult at these times. In contrast, the first and three-quarter moon results in tides with milder currents and milder conditions. It’s due to the fact that the tide has a greater impact on dive conditions at many of Bali’s dive sites than does the weather season.
Bali’s weather is always warm and fairly constant, with daily high air temperatures ranging from 30-35C / 86-95F, and nightly lows ranging from 24-26C / 75-78F. Despite this, the weather in the mountains is significantly cooler.
There are two distinct seasons in Bali due to the patterns of wind and rain. During the dry season, from May to September, temperatures remain unchanged. The wet season, on the other hand, occurs from November to March.
You can dive in Bali any time of year. Certain dive sites, such as Nusa Penida and Padang Bai, are most popular from June to October. From June to October, the mola mola (giant ocean sunfish) is most common when colder water from the depths of the ocean rises. During the remainder of the year, sea temperature ranges from 26-28C / 78-83F, but it occasionally drops below 20C / 68F.
The tide is strongly influenced by the moon. During the full and new moon phases, when the moon and sun are aligned, the tides surge in what is known as a spring tide, producing extreme high and low tides. Drift diving can be quite difficult then. Tides are more moderate and flowing during the first and third quarter phases of the moon. At many of Bali’s dive sites, the tide has a stronger effect on dive conditions than the weather season does.
