When is whale shark season in Holbox?

The official season runs from June to August, with July as the peak month. Sightings occasionally happen from mid-May through mid-September, but the central months are the most reliable.

Month-by-month calendar

Late May: the first sightings begin. Fewer people, but lower and irregular odds.
June: the season starts strong. Good odds and not yet the July saturation.
July: the peak month. Maximum concentration of sharks and over 95% sighting probability. Also the busiest.
August: excellent, similar to July, with many sharks present.
Early September: season's close. Sightings still happen, with fewer people.

Chances of a sighting

During peak season (July–August), the probability exceeds 95%. They are wild animals, so nothing is 100% guaranteed, but Holbox offers some of the best conditions in the world. In the rare case of no sighting, we refund the bracelet cost.

Weather and sea during the season

Temperature: summer heat (28–33 °C / 82–91 °F), warm waters and good visibility.
Rain: possible brief afternoon showers; departures are early, when the sea is calmest.
Sea: calmer in the morning; that's why we set sail around 7:00 am.
Bring biodegradable sunscreen (mandatory).

High vs low season: price and crowds

The tour price stays stable ($2,800 MXN, all-inclusive), but the experience changes: July and August see more demand and more boats, so book early. If you prefer fewer people, aim for June or early September. Accommodation does get pricier in high season.
