Farne Islands, England: Underwater Puppies of the North Sea
Dive Highlights: Cold Water, Boat Dives, Aggregations

Lying just off Northumberland’s rugged coast, the Farne Islands are the place to head if you’re feeling youthful. Here, curious, playful and utterly unafraid gray seals treat divers as entertainment. They’ll nibble your fins, blow bubbles in your face, barrel-roll past your mask and generally behave like overly excited golden retrievers.
August hits the sweet spot. Pups born earlier in the year have grown bold and inquisitive, water temperatures reach their annual peak, and lengthening daylight extends dive windows. Kelp forests sway beneath the surface, and the zooming, twisting seals constantly make eye contact. Pack your drysuit and a spirit of adventure. —Candice Landau

G.P. Schmahl/NOAARuby brittle stars in Flower Garden Banks National Marine Sanctuary.
Each August, under the glowing waning gibbous moon, the reefs of the Gulf of Mexico’s Flower Garden Banks National Marine Sanctuary come alive with life, or rather, life in the making.
Corals pop their gametes out into the surge, hoping for a miracle of conception, and so do the lesser-known ruby brittle stars. As the sun disappears from view, male brittle stars clamber atop the corals in writhing piles to shoot their shot, releasing plumes of brick-red sperm into the water. At the same time, females perch on their tippy-toes to release eggs for fertilization.
Divers can catch these spindly invertebrates in the act on the eighth night after the full moon. So mark your calendar! You won’t want to miss this spectacle. —Ariella Simke

Bali, Indonesia: Here Comes the Sunfish

Travels to the Island of the Gods promise otherworldly moments above the surface and below. You can spend your days in Bali witnessing fascinating ceremonies at Hindu temples and surfing epic waves between scouting for harlequin shrimp and burrowing octopuses in the waters off Tulamben and diving the walls of Menjangan Island.
Plan your visit from June to October to hit the sweet spot of giant ocean sunfish season, when massive, slab-shaped mola mola—the heaviest bonefish in the world—are frequently seen by divers in the waters of Nusa Penida, a small island off Bali’s southeast coast.
Dive sites like Crystal Bay and Manta Point and cleaning stations around the island are among the best spots in the world for entering the water with these fascinating pelagics that propel themselves forward by flapping their large dorsal and anal fins while their bodies stay strikingly rigid. —Terry Ward

Vanuatu: Luxury Liner Turned War Relic
Dive Highlights: Boat Dives, Wrecks, Shore Diving Options
Candice LandauCoral covers the bow of Vanuatu’s SSPresident Coolidge.
Resting on its side in the waters off Espiritu Santo, the SS President Coolidge ranks among the world's most accessible large shipwrecks. Not only that but it’s divable by shore and boat. This 654-foot former luxury liner turned troop carrier struck friendly mines in 1942 and now lies between 70 and 240 feet, a time capsule of wartime in the Pacific.
Large open cargo holds make it possible to explore some of the wreck’s treasures, including military jeeps, helmets, rifles and medical supplies. If you’ve taken technical diving classes, it’s also possible to penetrate the wreck and view chandeliers, ceramic toilets lined in rows and “The Lady,” a porcelain statue that has become the wreck’s signature image.
The wreck's gradual slope means divers of varying experience can explore different sections, though deeper compartments demand technical training and careful gas planning.
But don't pack up when the sun drops. After dark, the President Coolidge transforms into one of diving's rarest spectacles. Flashlight fish emerge from the wreck's recesses, their bioluminescent organs blinking like underwater fireflies against the black water. Rather than feeling as though you’re diving a wreck, suddenly you feel as though you’re in a planetarium, with stars winking in and out of existence. Few places on Earth offer this phenomenon so reliably. August is a great time to go as the seas are calm, water is warm and visibility can exceed 100 feet. —Candice Landau

Colombia: Thrill and Chill
Dive Highlights: Boat Dives, Aggregations, Big Animals, Photo Opps
The archipelago of San Andres, Providencia and Santa Catalina blends Afro-Caribbean and Hispanic culture into a laid-back Colombian escape. Whether you’re seeking relaxation, adventure, culture or fiesta—or a mix of all four—you’re sure to find it among the region’s turquoise water and easy island pace.
San Andres, the largest of the islands, is lively and accessible, with easy shore dives, plenty of macro life and more than 40 dive sites suitable for all levels. Providencia, a lush volcanic island, offers a quieter, more rugged underwater experience, boasting dramatic walls, endangered pillar coral and frequent reef shark encounters. And tiny Santa Catalina is a picturesque topside pit stop.
July and August are considered Colombia’s mini dry season. For divers, that means warmer, clearer water and lighter currents to match the archipelago’s easy-going vibe. —Kristin Paterakis
