Best Time to Dive in Playa del Carmen

Playa del Carmen offers diving twelve months a year. Cenotes stay at a constant 25°C, Cozumel is accessible year-round and the Caribbean Sea rarely disappoints. But some experiences are seasonal: bull sharks from November to March, and whale sharks from May to September.

Choosing the right dates can be the difference between a good dive trip and one you will remember for years. This guide goes month by month: what you can see, what you miss and what makes each period worthwhile. Practical, direct and designed to help you plan your trip with Scuba Alux.

January and February — The best time for shark lovers

January and February are the key months for bull shark diving in Playa del Carmen. Pregnant females have been gathering off Mamitas Beach for several weeks, and the number of sharks per dive is at its highest. Seeing 5 to 15 sharks on a single dive is not unusual when the season is good.

✅ Pros	❌ Cons
Bull shark peak: 5-15 sharks per dive	No whale shark: the season does not start until mid-May
Exceptional visibility in cenotes and Cozumel	The Caribbean Sea can be slightly cooler, around 24-26°C; a 5 mm wetsuit is recommended
High diving season, with a lively atmosphere in town	Boat spots for Playa del Carmen, Cozumel and bull shark dives sell out earlier
Cenotes are excellent all month	Higher demand: booking in advance is important

Best for: Best for divers who want bull sharks as the main experience. This is when the highest concentration of females is usually found off Mamitas Beach.

March — A transition month with almost everything available

March is the closing month of the bull shark season. Sightings are still good in most years, although the number of sharks per dive starts to drop compared with January and February. Overall conditions are excellent: the water begins to warm up and the weather on land becomes very pleasant.

✅ Pros	❌ Cons
Bull shark still active: end of season	Fewer bull shark sightings than in January and February
Water temperature starts to rise	No whale shark yet
Cenotes and Cozumel in excellent condition	Easter holidays may increase demand in town
Very pleasant weather on land	—

Best for: Best for divers who still want a chance of bull sharks combined with great general conditions. If your trip overlaps with Easter, book early.

April — Quiet diving and ideal water

April is for divers who prioritise dive quality over big pelagic encounters. The water is at an ideal temperature, visibility in Cozumel is excellent and cenotes run normally. Without the pressure of peak season, the underwater experience is quieter and often more enjoyable.

✅ Pros	❌ Cons
Water at 27-28°C: ideal for diving	No bull shark: season closed
Excellent visibility in Cozumel and spotted eagle ray season, with better chances of seeing them	No whale shark yet: still a few weeks away
Fewer tourists than in peak months	An in-between month without a headline animal
Cenotes start to get a very special light	—

Best for: Best for divers who prioritise Cozumel and cenotes without peak-season pressure. Excellent conditions, fewer people and usually more reasonable flight and hotel prices.

May — Whale shark season begins

May marks the start of whale shark season in the Riviera Maya. The first individuals begin to appear, although the largest groups usually arrive in July and August. It is a great month for combining whale shark snorkelling with cenotes and Cozumel in the same trip, while prices are still reasonable.

✅ Pros	❌ Cons
First whale shark sightings	No bull shark: wait until November
Warm, comfortable water around 28°C	Whale shark groups are still small; July and August are more spectacular
Beautiful light in the cenotes	Intense heat on land, although it is not a problem underwater
Cenotes and Cozumel are in great shape	—

Best for: Best for anyone who wants to combine whale shark, cenotes and Cozumel in one trip. A strong transition month into summer.

June — Heat on the surface, wonders underwater

June is very interesting for divers looking for good value. Whale shark season is underway and groups grow week by week. Cenotes are in excellent condition: strong light at certain times of day, a constant 25°C and perfect visibility. Cozumel remains exceptional.

✅ Pros	❌ Cons
Whale shark with growing groups	No bull shark
Cenotes at a perfect constant 25°C	Very intense heat on land: you will appreciate time underwater
Lower prices than July and August	Fewer whale sharks than during the July and August peak
Very good conditions in Cozumel	—

Best for: Best for divers on a tighter budget who want the whale shark experience without July and August peak-season prices.

July and August — Whale shark peak

July and August are the headline months for whale shark. Dozens of individuals can gather in a single sighting, making this one of the most spectacular snorkelling experiences on the planet. For divers, cenotes are at their most photogenic, with natural light entering at perfect angles during the early morning.

✅ Pros	❌ Cons
Whale shark peak: dozens of individuals	No bull shark: wait until November
Cenotes with spectacular natural light	High tourism season: more people in town
Water at 29-30°C: the Caribbean at its warmest	Book well in advance due to high demand
Excellent Cozumel diving with gentler summer currents	Very intense heat out of the water

Best for: Best for experiencing whale shark at its most spectacular. If you travel with family or non-divers, whale shark snorkelling is accessible without a diving certification.

September — The quietest month of the year

September is the quietest month of the year in Playa del Carmen and, paradoxically, one of the most interesting for a certain type of diver. Cenotes are almost empty; you may dive Dos Ojos or Chac Mool with barely another group in the water. The underwater experience feels completely different from January or August.

✅ Pros	❌ Cons
Lowest prices of the year	No bull shark yet: season starts in November
Cenotes almost to yourself	Last weeks of whale shark, with smaller groups
Highly personalised attention in a quiet destination	Some services may have reduced availability compared with high season
Warm water and flexibility to combine dives	—

Best for: Best for divers who avoid crowds and want a more intimate experience. Cenotes in September feel totally different: quiet underwater and very personalised attention.

October — The perfect bridge month

October is a very underrated month for diving in Playa del Carmen. Conditions are excellent: the water remains warm, Cozumel visibility is perfect and cenotes work as usual. With no headline pelagic species and no high-season pressure, prices drop and underwater experiences are very calm.

✅ Pros	❌ Cons
Low prices: full low season	No bull shark or whale shark
Water still warm at 28-29°C	If you want big pelagics, it is worth waiting until November
Perfect visibility in cenotes and Cozumel	Lower visitor numbers mean less atmosphere than other months
Fewer waits and fewer crowds	—

Best for: Best for divers who want Cozumel and cenotes at a good price, without waiting times or crowds. Very underrated if dive quality matters more than large animal encounters.

November — Bull shark season begins

November marks the return of female bull sharks off Mamitas Beach. Sightings start with smaller groups than in January or February because the females arrive progressively, but the season is already active. Weather on land is among the best of the year: dry, cooler and very pleasant.

✅ Pros	❌ Cons
First bull shark sightings of the season	No whale shark: season closed until May
Perfect cenote conditions	Fewer bull shark sightings than in January and February
Very pleasant weather as the heat starts to drop	Book early: the season starts to fill up
Less pressure than January and February	—

Best for: Best for divers who want bull shark without the pressure of January and February. Fewer people, first females arriving and some of the best weather of the year on land.

December — The most complete month for diving in Playa del Carmen

December is the most complete month of the year for diving in Playa del Carmen. Bull shark season is active and numbers grow week by week towards the January peak. Cozumel conditions are exceptional, with some of the best visibility days of the year. Weather on land is dry, bright and pleasant.

✅ Pros	❌ Cons
Bull shark active and increasing in numbers	No whale shark
Exceptional visibility in Cozumel and cenotes	Higher prices around Christmas and New Year
Perfect weather: dry and pleasant on land	Small-group spots sell out; book in advance
The full combination: bull shark, cenotes and Cozumel	The most requested month after January and February
