What you will see

June in St. Maarten and Saba is a wonderful time for marine life encounters, with a particularly rich tapestry of reef inhabitants and some exciting pelagic possibilities. While large-scale seasonal aggregations are less pronounced than in certain other global hotspots, the everyday reef life is truly spectacular. Expect to be greeted by an explosion of colorful reef fish – parrotfish, angelfish, butterflyfish, and snappers are in abundance, darting amongst healthy hard and soft corals. Keep an eye out for moray eels peering from their crevices, and various crustaceans, from tiny arrow crabs to larger lobsters, hiding in the reef structure. The sheer density and diversity of macro life will also keep keen photographers busy, with nudibranchs, gobies, and blennies frequently spotted.

While June isn't a peak month for massive whale sharks or manta ray aggregations like some Indian Ocean destinations, you still have a decent chance of encountering larger pelagics in the deeper waters around Saba, particularly on its renowned pinnacles. Reef sharks, such as Caribbean reef sharks and nurse sharks, are year-round residents and are frequently seen patrolling the deeper sections of the reefs. Occasional sightings of eagle rays gracefully gliding by are also not uncommon, especially when drifting over sandy bottoms adjacent to the reef. The generally calm conditions also mean that creatures like turtles – green, hawksbill, and loggerhead – are often more relaxed and easier to observe as they graze on seagrass beds or rest on coral bommies.

Beyond the typical reef inhabitants, June can sometimes bring opportunistic sightings. Schools of tarpon and barracuda are often spotted hunting in the blue, and if you’re lucky, you might even catch a glimpse of schools of jacks or even tuna passing by. The healthy coral ecosystems act as magnets for a wide array of species, ensuring that every dive offers something new and exciting. You’ll be constantly pointing things out to your buddy, from a camouflaged scorpionfish to a shy octopus changing colors on the reef.

Top dive sites this month

For those diving St. Maarten and Saba in June, certain dive sites truly shine due to the prevailing conditions and the marine activity. Around Saba, the famous "Pinnacles" – Diamond Rock, Man of War Shoals, and Third Encounter – are absolutely spectacular. These underwater mountains rise dramatically from the seabed, creating nutrient-rich upwellings that attract larger pelagics and support an incredible diversity of reef fish. The clear June waters allow for breathtaking views of these formations and the abundant life that congregates around them. These sites are typically better suited for more experienced divers due to potential currents and depth, but the rewards are immense.

Closer to St. Maarten, the wreck of the Antilles is a must-dive in June. This 60-meter (200-foot) cargo ship, sunk in 1993, is now a thriving artificial reef, teeming with marine life. The excellent visibility this month allows you to appreciate the full scale of the wreck, with schools of fish swirling around the superstructure and moray eels making their homes in various compartments. For a shallower, vibrant reef experience, Creole Rock, a marine park area, is fantastic for all levels. Its healthy coral gardens are home to countless reef fish, and it’s a brilliant spot for macro photography. In June, the generally calm waters around these St. Maarten sites make for relaxed and enjoyable dives.

Practical tips for your trip

Given the wonderfully warm water temperatures in June (27-29°C / 81-84°F), you'll likely find a 3mm shorty wetsuit to be more than adequate for warmth and protection. Many divers even opt for just a dive skin or board shorts and a rash guard. Remember that multiple dives over several days can sometimes make you feel a bit cooler, so having a thin full-length suit isn't a bad idea if you tend to get cold easily. This month generally suits divers of all levels, from beginners looking for calm, clear conditions to advanced divers eager to explore the deeper pinnacles and wrecks. The diverse array of sites ensures there's something for everyone, but always communicate your experience level with your dive operator.
