Frequently Asked Questions

Is there good diving on the Big Island?

Absolutely. The Big Island is considered one of the best diving destinations in the world. Its volcanic underwater topography creates unique lava tubes, arches, and caverns. The coast is protected from major ocean swells, resulting in excellent visibility and calm conditions. It’s famous for reliable encounters with manta rays, turtles, dolphins, and a vast array of endemic reef fish.

What are the best months to scuba dive in Hawaii?

You can scuba dive in Hawaii year-round, but the best months are typically during the summer (April to October) when the water is warmest and the seas are calmest, especially on the Kona coast. Winter months (November to March) can bring larger swells, but Kona’s leeward side remains relatively protected, offering great diving Big Island conditions most of the year.

Is Kona good for scuba diving?

Kona is exceptional for scuba diving. Its location on the leeward side of the Big Island shields it from the prevailing trade winds, resulting in consistently calm, clear waters. This makes it the epicenter for diving Hawaii Big Island, with world-renowned sites like the Manta Ray Night Dive, Black Water dives, and countless healthy coral reefs.

Is it better to snorkel or scuba dive in Hawaii?

It depends on what you want to experience. Snorkeling is fantastic for seeing vibrant, shallow reefs and is accessible to almost everyone. Scuba diving allows you to explore deeper, see different marine life (like sharks in lava tubes or garden eels on sandy bottoms), and experience the feeling of weightlessness. For the most immersive experience, scuba diving Big Island is unparalleled.

Which Hawaiian island is best for scuba diving?

While all Hawaiian islands offer great diving, the Big Island (specifically the Kona coast) is widely considered the best overall. It boasts the highest biodiversity, the most unique volcanic underwater landscapes, and the most reliable big animal encounters, including the world-famous Manta Ray Night Dive.

When to dive Kona?

The best time to dive Kona is generally in the morning when the seas are calmest and visibility is at its peak. Year-round diving is excellent, but summer (April-October) offers the warmest water and flattest conditions. However, winter diving is also fantastic and offers the chance to hear humpback whales singing underwater. Any time is a good time for Kona diving.
