Belize, home of the famous Blue Hole, was one of Jacques Cousteau’s favorite dive spots.
There really isn’t a bad time to dive in Belize, but there are different times to dive in Belize according to what you want to see and experience most.
In this article, we take a look at diving in Belize throughout the year and what’s on offer from season to season.
Diving in Belize: June Through November
The rainy season in Belize begins in late June and runs through to November. That said, you can still expect 12 to 24-meter / 40 to 80-foot visibility at off-shore dive sites. If you don’t mind a bumpy boat ride, you can enjoy the best of Belize with fewer tourists at this time of year.
The water temperature in Belize doesn’t fluctuate much, but it’s the warmest from June to November (26-29°C/79-84°F). Expect similar temps topside.
Starting in October, you may have the opportunity to experience Nassau grouper mating season in Belize. Thousands of these fish descend on the Cayes to mate and give birth to their young from October through December.
If you want to dive in Belize but are looking for a more affordable way to do it, these could be the months for you. Flight prices tend to be lower and hotels and dive operators often have some great deals and promos up for grabs! Booking last minute doesn’t guarantee you a place but could result in even further discounts. Please note, however, that the general policy in Belize is no refunds for cancellation of a trip.
Diving in Belize: December to April
By early December, the rains begin to taper off and water temperatures drop slightly (just a few degrees). Expect water temperatures in the mid 20s Celcius / upper 70s Fahrenheit. Air temperatures during these months are slightly cooler as well.
The dry season is also peak tourist season. When temperatures drop in the northern hemisphere, the sunny beaches of Belize are a popular place to warm up.
Peak tourist season means that accommodation prices are at their highest during these months. Flight prices are also at a premium during this time.
Best Time to Dive in Belize: April, May and June
What’s the best time of year to dive in Belize? What is the best time to see whale sharks in Belize? While this isn’t peak tourist season, April to June is a great time for divers, and we recommend these months for the following reasons:
- General (non-diving) tourist crowds die down starting in April.
- Underwater visibility is at its peak – a major plus for wide angle photographers.
- April, May and June are the best months to see whale sharks in Belize’s tropical waters.
- Prices are more realistic than during peak season for flights and accommodation.
- The rainy season starts in June (so consider June a shoulder month if you want the best chance of avoiding rainy days).
The Blue Hole
It’s impossible to report about Belize and not mention more about the Blue Hole. This dive site is one of the most famous sites in the world.
In 1971, aboard his ship the Calypso, Jacques Cousteau explored the Blue Hole for the first time. During this expedition, Cousteau’s team discovered the hole had several ledges as it vertically narrowed. This limestone formation has ledges at 21 m (69 ft), 49 m (161 ft), and 91 m (299 ft) making it suitable for advanced divers. What’s most interesting about the Blue Hole is its history. The Blue Hole is home to submerged caves that contain stalactites that were formed above land. Now submerged beneath the waves these stalactites have created a timeline of the Hole’s existence – and gradual sinking. Not only is its depth significant, it’s also over 300 m (1,000 ft) across.
In 2018 a submarine expedition attempted a deep dive to find the bottom of the Hole and was able to scan the Hole with sonar up to 91 m (300 ft), less than Cousteau’s initial expedition that reported a depth of 125 m (410 ft).
Today, the Blue Hole is one of the most sought after dive sites on the planet. The ‘Hole’ is also home to some of the largest freediving competitions in the world.
