Belize is the only country in Central America without a coastline on the Pacific Ocean (only the Caribbean Sea to its east), and the only one in the region with English as its official language. With more than 400 islands, white sandy beaches, and the second-longest barrier reef in the world, Belize is definitely a world-class scuba diving destination!
The Belize Barrier Reef is the world’s second-largest barrier reef, stretching over 300 km along the Caribbean coastline. This vibrant reef system, combined with numerous atolls, cays, and the famous Great Blue Hole, makes Belize one of the most iconic diving destinations in the world.
Diving in Belize offers a mix of stunning coral reefs, dramatic walls, cavern systems, and thrilling deep dives. Divers can encounter reef sharks, nurse sharks, stingrays, eagle rays, tarpons, groupers, and an abundance of colorful tropical fish. Currents are generally mild, making Belize accessible for divers of all levels, though some sites offer drift diving for a more exhilarating experience.
The subtropical weather in Belize means it is warm year-round, particularly along the coast. This make diving here can be all year around. Sea turtles nest on the sandy beaches from June to August. Whale sharks sightings are common from March to June along the southern barrier reef.
The water temperature is pleasantly warm during the summer at 30°C and a comfortable 26°C in winter. Off the barrier reef and atolls, visibility is often 30 metres or more year-round , it’s slightly less inside the reef.
Liveaboard trips are often runs for 8D/7N to the outer atolls past the barrier reef, throughout the week you will dive at Turneffe and Lighthouse Reef. Sheer walls like Painted Wall, Half Moon Caye Wall and Quebrada are adorned with huge crimson gorgonians and wandering, lilac rope sponges. Weather permitting; divers explore the mystical Blue Hole, a collapsed freshwater cave system.
