2026-2027 season
Bull Shark Season in Playa del Carmen
Every winter, bull sharks return to the waters off Playa del Carmen. The tourism season is concentrated between November and March, but these are wild animals: arrival dates, shark numbers and the end of the aggregation vary from year to year.
This guide is for choosing dates and planning the trip. For behaviour rules, photography, observation and attraction, see our separate guide to responsible bull shark diving. If your dates are already set, check bull shark diving options, prices and availability in Playa del Carmen.
2026-2027 season: November to March
The management plan for the Mexican Caribbean Biosphere Reserve identifies a dedicated Bull Shark Public Use Subzone off Playa del Carmen and describes the aggregation mainly from November through March, when water temperature is around 26 °C. Tourism activity is normally organised from November 1 to March 31.
That does not mean every shark arrives on November 1 or leaves on March 31. The dates help you plan; sightings should never be sold as a guarantee.
What is the best month?
January and February are usually the most requested months because the season is well established. November can produce excellent encounters, although the first weeks are more variable. March is still part of the season but sits at the final end of it.
| Part of the season | What usually happens | What to keep in mind |
|---|---|---|
| November | The first arrivals appear and the season gets underway. | This is the most variable part of the season. |
| December | Shark presence is usually more established. | A good option before the busiest weeks. |
| January and February | The core of the season and usually the most requested months. | Booking ahead is sensible. |
| March | The final stretch of the tourism season. | Numbers can start to fall as conditions change. |
If you travel at the beginning of November, you can also combine diving with Day of the Dead in Playa del Carmen.
If your dates fall in December, see why Christmas is an especially complete time for a Playa del Carmen dive trip.
What we know about the Playa del Carmen aggregation
Research has confirmed the presence of pregnant females at this site. A study using a fully submersible ultrasound detected embryos in free-swimming bull sharks and suggested the area may be important during gestation.
What science has not established is one simple, definitive reason for the aggregation. Temperature, food availability, reproductive cycles and other environmental factors may all play a role. For that reason, we have removed overly simple claims that directly attribute the sharks' arrival to nutrients from the cenotes.
You can read the study in Frontiers in Marine Science if you want the research behind this.
Depth, certification and conditions
The aggregation site is on a sandy bottom and common dive profiles can reach roughly 20-24 metres, depending on the exact site, conditions and dive format. The scientific study cited above was carried out at 24 metres.
That is why “Open Water is always enough” is too simplistic. Open Water depth limits can be shallower than some common profiles. Scuba Alux confirms the required level before booking based on the planned dive, your certification and recent experience.
Winter water can feel noticeably cooler than summer. Wetsuit choice depends on the actual temperature and your own cold tolerance, so tell us if you tend to get cold.
What a bull shark trip looks like
The day starts with a specific briefing covering the dive profile, group positioning, signals and the behaviour expected when sharks approach. You then travel to the aggregation area and dive according to the conditions and planned format.
In Playa del Carmen you will hear the terms observation and attraction. We keep the detailed comparison out of this season guide on purpose. Our responsible bull shark diving guide covers the differences, diver behaviour and what to look for in an operator.
How many sharks will you see?
There is no guaranteed number. The official management plan records reports of dives where 12 to 24 animals were counted, but that is a documented observation, not a promise for your dive. Numbers and distance can vary substantially from day to day.
If an operator guarantees a specific number of sharks before knowing how the season is developing, treat that claim cautiously.
Building bull sharks into a dive trip
Bull shark season overlaps with excellent diving across the Riviera Maya. Over several days you can combine the encounter with:
- Cenotes: from open-water-friendly sites to deeper options for Advanced divers. See cenote diving.
- Cozumel: reefs, walls and drift diving. See Cozumel diving.
- Playa del Carmen reefs: useful as an acclimatisation dive if you have been out of the water for a while.
Already know your travel dates?
Send us your certification, approximate number of logged dives and dates. We will tell you which profile fits you and how to combine it with cenotes or Cozumel.

When is bull shark season in Playa del Carmen?
Tourism activity is concentrated from November 1 to March 31. Actual shark presence can begin or end earlier or later because these are wild animals.
Which months are usually best?
January and February are usually the most requested months because the season is well established. November and March are also part of the season but can be more variable.
Can you guarantee how many sharks we will see?
No. The management plan records reports of dives with 12 to 24 animals, but no number should be presented as a guarantee for a specific dive.
What certification do I need?
It depends on the planned profile. Some dives can reach roughly 20-24 metres, so the required level may be above Open Water. Scuba Alux confirms this before booking based on certification and experience.
Are observation and attraction the same thing?
No. Observation uses no food to attract sharks. Attraction may use bait as an olfactory cue within the relevant protocol. Our responsible diving guide explains both formats.
Can I combine bull sharks with cenotes or Cozumel?
Yes. It is a common combination for a multi-day trip and lets you mix the seasonal shark encounter with cenotes, Playa del Carmen reefs and Cozumel.
