Diving in Belize in November

Conditions in November

If you're looking for that sweet spot between the seasons, November in Belize is your answer. This month marks the transition from the rainy season to the dry season, offering a fascinating blend of conditions that often works in a diver's favor. The official hurricane season technically ends on November 30th, so while the risk of major storms is very low, you should still expect the occasional tropical shower, usually in the afternoon or overnight. These brief downpours rarely disrupt a full day of diving and have a wonderful side effect: they wash the air clean and leave behind lush, vibrant landscapes on the cayes. The upside of this transitional weather is that you bypass the peak tourist crowds of December and January while still catching the start of the prime diving season.

Out on the atolls where our liveaboards operate, the sea conditions are generally improving throughout November. Surface chop can still be present, especially on longer crossings, but it’s typically manageable and calms down significantly as the month progresses. Once you’re in the lee of the atolls like Turneffe or Lighthouse Reef, the dive sites are well-protected. The real reward is underwater. Water temperatures are delightful, hovering between a very comfortable 27-29°C (81-84°F). You’ll be perfectly warm for multiple dives a day without needing bulky exposure suits. Visibility is also typically excellent, ranging from 20 to over 30 meters (65-100+ feet) on the outer walls. After a heavy rain, visibility might temporarily drop in some of the inner lagoon sites, but the world-class wall dives on the outer edges of the atolls almost always retain their gin-clear quality.

What you will see

Belize’s Barrier Reef is a year-round spectacle of life, and November is a fantastic time to witness its buzzing, vibrant state. The corals, refreshed by the summer rains, are thriving. You won't find the massive whale shark aggregations of spring, but what you will find is arguably even more consistent and rewarding: incredibly healthy reef systems teeming with resident populations of large marine life. The outer atolls are patrol grounds for Caribbean reef sharks and majestic nurse sharks, which you’ll see on nearly every dive, often resting under ledges or cruising curiously along the walls. Keep a keen eye out in the blue for spotted eagle rays, which often travel in pairs or small groups, gliding effortlessly past the reef edge. Southern stingrays are also a common sight, camouflaging themselves on the sandy bottoms.

The sheer fish count is staggering. As you drift along the dramatic coral walls, you’ll be surrounded by enormous, swirling schools of horse-eye jacks, Creole wrasse, and blue tangs that move as one unified organism. Hawksbill and green turtles are frequently encountered, munching on sponges or simply enjoying a rest on the reef top. Macro life thrives here too, for those with a patient eye. Look for Pederson's cleaning shrimp in anemones, cryptic arrow crabs scuttling on sponges, and the occasional seahorse hiding in the seagrass beds of the inner lagoons. While November doesn't have a specific spawning aggregation event like the groupers in winter, the overall biomass and energy of the reef are at a high point, making every dive a rich and dynamic experience. It’s classic Caribbean diving at its absolute best.

Top dive sites this month

A liveaboard trip in November unlocks the holy trinity of Belizean diving: Lighthouse Reef, Turneffe Atoll, and, of course, the legendary Great Blue Hole. Your itinerary will be built around these iconic destinations, and November conditions allow for prime access. The Great Blue Hole itself is a must-do for the sheer geological wonder of it. Descending into the deep blue abyss to witness the immense submarine stalactites at 40 meters (130 feet) is an experience that stays with you forever. While it's not a dive known for prolific marine life, you’ll often see a few curious reef sharks patrolling the drop-off as you descend.

The real stars of Lighthouse Reef, however, are the surrounding walls. Half Moon Caye Wall is arguably one of the best wall dives in the entire Caribbean. It’s an underwater cliff exploding with life, from huge barrel sponges and gorgonian fans to an almost guaranteed escort of reef sharks and eagle rays. Another gem here is Long Caye Aquarium, a site that lives up to its name with its aquarium-like clarity and dense populations of reef fish. Further west, Turneffe Atoll offers a different flavor of diving. We always aim for a dive at The Elbow, a thrilling drift dive at the southernmost point of the atoll. The converging currents here attract the big stuff, and it's your best spot to encounter massive schools of snappers and jacks, as well as larger pelagic hunters cruising in from the deep.

Practical tips for your trip

Packing for a Belize liveaboard in November is straightforward. With water temperatures comfortably in the high 20s Celsius, most divers will be perfectly happy in a 3mm shorty or a full-length 3mm wetsuit. If you tend to get cold after multiple dives, a 3mm full suit is a safe bet, but anything thicker is unnecessary. This month is fantastic for a wide range of divers. While there are plenty of relaxed, shallow reef dives suitable for all levels, a Belize liveaboard itinerary truly shines for intermediate to advanced divers. The exhilarating wall dives, the potential for currents at sites like The Elbow, and the mandatory deep dive at the Blue Hole mean you’ll get the most out of the trip if you are comfortable with your buoyancy and have some experience with drift and deep diving procedures.

November marks the beginning of the high season, so liveaboard availability starts to tighten up. We highly recommend booking your spot several months in advance to secure your place on the best boats. When packing, don't forget your reef-safe sunscreen, polarized sunglasses, and a hat for the sun-drenched surface intervals. Given that it's the end of the rainy season, it’s also wise to pack a light rain jacket for the occasional shower. Most importantly, bring your certification cards, especially your advanced open water card if you plan on diving the Blue Hole. Get ready for a week of spectacular diving, where you’ll explore remote atolls and pristine reefs far from the day-boat crowds.
