Hawaii - Manta Dive and Snorkel Tour in Kona

When Is the Best Time

The manta rays are here abundant at this specific spot throughout the year. So there isn't a precise season for manta rays. Therefore, the snorkel and dive tour is offered year-round, always in the evening when it is dark outisde. However, sometimes ocean conditions can spoil the trip, especially in the winter and spring from November until March/April. It's a popular tour and likely to be sold out days before, particularly during weekends. We spotted plenty of manta rays; some almost touched us. 

Avoiding Crowds

The popular manta tour is often fully booked even in the shoulder season. Up to 150 people watch this awesome "dinner show" in the sea each evening. Therefore the advanced booking is recommended. Nevertheless, everybody gets enough space to hold the floating device also to take pictures.

Shoulder Season

It starts in spring from mid-April to mid-June and in fall from September to November. It's busier during the "Golden Week" in Japan end of April until the beginning of May.

Peak Season 

It is utterly crowded when the Ironman takes place in October, also very busy with increasing summer rates, from July to August. Hawaii is overrun during Christmas, New Year's Eve and Independence Day week.

Weather and Ocean Conditions

The south and the west of Big Island experiences less rain. Kona is located in the west, therefore excellent to stay here for a couple of days. Showers frequently occur in Hawaii, especially late afternoon and during the night, but not that often in Kona. The Hawaiian climate is tropical but never too hot. There are only two seasons; the summer - dry season and winter - rainy season. Spring and autumn do not exist. The warm ocean temperatures of at least 77°F/25°C have an impact on the air temperature, which is mild the entire year. 

Summer - Drier Season

During summer, the drier season, the ocean is calmer, making snorkelling much easier, especially for beginners. The island is drier from May to October. Kona is often cloudy during the summer, reaching 87°F/31°C and night temps are around 73°F/23°C.

Winter - Rainy Season

Mauna Kea
Snow often occurs on Mauna Kea in winter.

In the winter, the rainy season, the sea can be turbulent; high waves can spoil your trip. Day temperatures are pleasant above 80°F/27°C and nights drop to 66°F/19°C.

Diving in Winter
  • Hammerhead Sharks can be spotted year-round most probable encounters are in January and February.
  • Whale sharks are more likely to spot between mid-December to mid-January.

Spotting manta rays up close was always on my bucket list. My friend Leif went to Kona for diving and told us about this thrilling experience. It is almost guaranteed to spot the mantas just next to you. Why?

Manta Ray with wide open mouth

Close to the airport of Kona is a manta ray "cleaning station". The tour operators position lights to the surface and the bottom of the sea. They call it a "campfire". The plankton gets attracted by the lights and the manta rays by plankton. Snorkelers hold themselves at floating devices which are also equipped with lights shining to the bottom. Divers are on the ocean floor and watch the spectacle.

Manta Ray

While the manta rays feed, they swim elegant, turn around and often come close to the surface and you. Sometimes I really thought they would bump into me, but they never even touched me. Manta Rays are not dangerous for human beings; it is the opposite. Never touch a manta ray! It can cause bacteria infiltration and infection from your hand.

Monk Seal in Kona

It was unbelievable we spotted six manta rays at the same time. It was so exciting I couldn't take many pictures or footage. It’s a memorable experience where Kona is one of the best places in the world. However, the tour takes part in the mantas' natural environment; it is not a zoo tour. It is rare, but it can happen that you don’t spot any on your trip. Plan ahead that you may have another evening available for this outstanding experience. The location is north of Kona, close to the airport. The spot is called "Manta Heaven", and it was an incredible experience. It is also a popular place for diving known as “Golden Eel Cove”. We came here for free-diving the next day and spotted a rare monk seal. Overall, Kona is an excellent spot underwater! 

Hawaiian Manta Rays Facts

Manta Ray up close

  • The Hawaiian manta ray species belongs to the Manta Alfredi. 
  • Big Island - Kona has the highest population density of all Hawaiian Islands, with more than 270 manta rays found in the vicinity of around 40 miles.
  • These manta rays don't migrate.
  • Usually, they reach 10 to 12 feet in width, but there is one here over 14 feet.
  • Names were given to all of them, identified by the pattern on their bellies.
  • They have the largest brains amongst all species of fish.
  • Manta Rays are capable of heating up and cooling down due to their "heat exchange system".
  • A female gives birth after 13 months. The young one is feeding independently immediately after it was born.
  • They cooperative feeders; means feeding in groups called "chain feeding" one by one on a fair share basis.
  • Since 2008 they are protected around Hawaii. 

Comments

Leif

The dive site Kona is good during the day. You can spot goat fish, jacks, moray eels and frogfishes. During the night the spot gets awesome as mantas are visiting the place to feed. You can spot up to 30 rays during the dive. Plankton gets attracted by the lights in the night, and the mantas come close to divers and snorkelers. It is one of the best night dives on earth.

Diving gives you another great perspective. I already did it a couple of times and it's always a breathtaking experience.
