Have you ever dreamed of swimming alongside a creature the size of a school bus—yet as gentle as a puppy? Whale sharks are among the ocean’s most magnificent creatures, and Belize offers a rare chance to see them up close. But like all good wildlife encounters, timing is everything.
In this guide, we’ll break down the best time to visit Belize for whale shark watching, share expert tips, and even include a wildlife calendar so you can plan around more than just one bucket-list experience.
Why Belize Is a Whale Shark Hotspot
Belize’s pristine coastline is part of the second-largest barrier reef in the world, and nestled within it lies the Gladden Spit and Silk Cayes Marine Reserve. This is the epicenter for whale shark encounters in Belize. But why here?
Between March and June, large schools of cubera, mutton, and dog snappers gather at Gladden Spit to spawn around the full moon. Whale sharks – filter feeders that can grow up to 40 feet, and flock to the area to feed on the released eggs. These gentle giants don’t bite, sting, or chase. They calmly cruise through the Caribbean waters, providing a peaceful and awe-inspiring experience for divers and snorkelers alike.
Belize has become a globally recognized destination for responsible whale shark watching thanks to its strict conservation rules and committed local guides.
When Is Whale Shark Season in Belize?
If you’re planning a trip around this phenomenon, it’s critical to understand when and why whale sharks appear.
Peak Season:
- Mid-March through June
- Most active around 2–3 days before and after the full moon
During these months, conditions align perfectly: spawning fish draw whale sharks, the water is clear, and tour operators are ready to take you out from Placencia or Hopkins.
Full Moon Dates to Watch: March 3, April 2, May 1, May 31, June 29
Plan your tour on the day of the full moon or the two days before/after for the best chance of an encounter.
Where and How to See Whale Sharks in Belize
The main launch points for whale shark tours are:
Placencia | Hopkins Village
Tours travel offshore to Gladden Spit, a protected marine area about 26 miles southeast of Placencia. Most excursions are half- or full-day trips and include professional guides, certified dive masters, and all necessary gear.
Snorkeling vs. Scuba Diving
- Scuba divers have better chances due to the depth (60–80 feet), but snorkelers can sometimes spot whale sharks closer to the surface.
- Some tour companies require a PADI Open Water certification for divers.
Price Range: $150–$250 USD depending on dive/snorkel option, group size, and inclusions.

- Waterproof camera or GoPro
- Snorkeling or dive certification card
- Motion sickness remedies (especially for offshore trips)
