Conditions in March
March in Belize is, quite simply, a diver’s dream. You're hitting the sweet spot at the tail end of the dry season, which means predictable, glorious weather both above and below the surface. Expect bright, sunny days with minimal rainfall, making for comfortable surface intervals and epic sunsets. Air temperatures typically hover around a pleasant 28-30°C (82-86°F), perfect for lounging between dives.
The sea state is generally calm and inviting in March, especially within the sheltered confines of the barrier reef. You might encounter some gentle swells offshore, but nothing that would typically disrupt diving operations. Water temperatures are beautifully warm, sitting comfortably between 26-28°C (79-82°F), so you'll be feeling cozy even during longer dives. Visibility is often outstanding, frequently exceeding 30 meters (100 feet), offering crystal-clear views of the vibrant coral ecosystems and teeming marine life. Currents can vary depending on the dive site, from mild drifts to more exhilarating pushes on offshore atolls, but your dive guides will always assess conditions carefully to ensure a safe and enjoyable experience for everyone.
What you will see
Belize in March is a vibrant tapestry of marine life, offering a truly immersive experience. While whale shark season typically kicks off a little later around the full moons of April, May, and June, March still offers incredible opportunities for pelagic encounters. Keep your eyes peeled for eagle rays gracefully gliding by, and the occasional hammerhead or Caribbean reef shark patrolling the reef edges. Schooling jacks and barracudas are a common sight, their silver scales flashing in the sun-dappled water. For those who appreciate the smaller wonders, the shallows are bustling with an incredible array of macro life, from delicate nudibranchs to camouflaged frogfish hiding amongst the sponges.
One of the true highlights of Belize diving is its phenomenal coral health. In March, with excellent visibility, you'll be treated to breathtaking expanses of hard and soft corals thriving in their natural glory. Look out for massive brain corals, towering elkhorn formations, and delicate gorgonians swaying gently in the current. These vibrant reefs are home to countless reef fish species, including angelfish, parrotfish, snapper, and grouper. Green sea turtles and hawksbill turtles are frequently spotted, often grazing placidly on seagrass or resting on coral heads. March is a fantastic time to witness the sheer biodiversity that makes the Belize Barrier Reef a UNESCO World Heritage site.
Top dive sites this month
Without a doubt, a trip to Belize in March demands a visit to the iconic Great Blue Hole. While not teeming with abundant coral life, the sheer scale and geological wonder of this massive sinkhole are truly awe-inspiring. Descending into its depths, you'll witness ancient stalactites formed when the cave was above sea level, and keep an eye out for reef sharks circling in its dark embrace. The visibility in March really enhances the experience, allowing you to appreciate the vastness of this natural marvel.
For more vibrant reef diving, the walls of the Turneffe Atoll and Glover's Reef Atoll are exceptional in March. At Turneffe, sites like "The Elbow" are renowned for their chances of encountering large pelagics, including eagle rays and reef sharks, pushed in by currents. The extensive coral gardens and abundant fish life there are a treat. Over at Glover's Reef, the pristine walls offer incredible biodiversity. Sites such as "Half Moon Caye Wall" and "The Aquarium" are packed with colorful corals, sponges, and a dazzling array of reef fish, often with playful resident turtles. The calm conditions of March are ideal for exploring these world-class atolls.
Practical tips for your trip
Considering the balmy water temperatures of 26-28°C (79-82°F) in March, a 3mm shorty wetsuit or even just a rash guard for sun protection will be perfectly adequate for most divers. If you tend to get cold easily or plan on multiple dives a day, a 3mm full suit might offer a bit more comfort, but anything thicker would likely be overkill. This month is fantastic for divers of all experience levels. The calm conditions and excellent visibility make it very welcoming for newer divers, while the opportunities for pelagic encounters and deep wall diving on the atolls provide plenty of exhilaration for more advanced enthusiasts.
Liveaboard availability in March can be competitive, as it’s a popular time to visit Belize. We strongly recommend booking your Blue Rides liveaboard well in advance to secure your preferred dates and vessel. Early booking not only guarantees your spot but can sometimes unlock better deals. When packing, think light and breathable clothing for onshore excursions. Don't forget reef-safe sunscreen, a wide-brimmed hat, sunglasses, and insect repellent for evenings. A dry bag is always a good idea for protecting your valuables on boat excursions. Be aware that most of Belize operates on US dollars and Belizean dollars (fixed at 2 BZD to 1 USD), and credit cards are widely accepted in larger establishments, but it's always handy to have some local currency for smaller purchases.
