Yes, but not the ones people mean. The sea off Dubai holds whale sharks, blacktip reef sharks and various small bottom-dwelling species, all of which are harmless to swimmers. Shark attacks in UAE waters are effectively unheard of, and swimming from a charter boat carries no meaningful shark risk.

The Arabian Gulf is shallow, averaging around 35 metres, very warm and very saline, which is a difficult environment for large pelagic predators. What it does support is smaller reef and bottom-dwelling species, plus seasonal visitors.
The one worth hoping for is the whale shark. They pass through Gulf waters, most often between April and September, and they are filter feeders: the largest fish in the sea, with no interest in and no capacity to harm a swimmer. Seeing one from a charter is rare and is the kind of thing crews remember for years.
Blacktip reef sharks are more common and generally under two metres. They are shy and leave the area when people arrive.
Sun is first, by a distance. Two hours on a swim platform in Dubai burns people who would not burn in an entire European afternoon, and the reflection off the water doubles the exposure.
Then boat traffic. This is a busy coast, and the reason charters anchor in specific sheltered spots rather than wherever looks nice is that the crew know where the traffic runs. Swimming away from the boat is the thing crews actually worry about.
Then currents, which are modest inside the Palm crescent and stronger in open water. Jellyfish appear occasionally and are a nuisance rather than a danger.
The two standard anchorages are behind the Palm Jumeirah crescent and among the World Islands. Both are sheltered, both are away from the shipping lanes, and both are shallow enough to see the bottom on a clear day.
Crews put the ladder down, stay on deck while people are in the water, and ask that nobody swims beyond the stern. That is standard practice everywhere and it is about traffic and currents, not about sharks.
The species that appear in the questions people are really asking (great white, bull, tiger) are essentially absent from the Arabian Gulf, and the reason is the water itself rather than luck.
The Gulf is a shallow, almost enclosed basin averaging around thirty-five metres, connected to the Indian Ocean only through the Strait of Hormuz. Summer surface temperatures exceed 33°C and salinity is well above ocean average because evaporation outpaces inflow. Large pelagic predators need deep, cooler, oxygen-rich water and long migration routes, and the Gulf offers none of those.
What thrives instead is a shallow-water community: reef fish, rays, small sharks, turtles and, seasonally, whale sharks passing through. It is a genuinely interesting ecosystem and it is not a dangerous one.
Realistically, on a normal three-hour charter with a swim stop behind the Palm, marine life is a bonus rather than a feature. The commonest sightings by a wide margin are fish schooling under the boat at anchor and the occasional ray passing over sand.
Dolphins are the sighting people hope for and they do happen: Indo-Pacific humpback and bottlenose dolphins live along this coast, most often seen early in the morning and further offshore. A dawn charter or a fishing trip has a far better chance than an afternoon run along JBR.
Turtles show up near the Palm breakwaters and around the World Islands. Whale sharks are a genuine rarity. Nobody should book a charter expecting wildlife, and everybody should keep an eye out anyway.
The honest answer is that almost nobody does, and those who do are usually looking at a blacktip reef shark under two metres that is already leaving. They are shy animals and a group of people getting into the water is exactly what makes them go.
Standard practice if you see one is unremarkable: do not chase it, do not corner it against the boat, and get back aboard calmly if you would rather. Tell the crew, who will decide whether to move the anchorage, usually not, and usually because it has already gone.
The behaviour that would actually create a problem is the behaviour nobody on a charter engages in: spearfishing with a catch on your belt, swimming among a baitfish boil, or getting between a ray and the open water. Ordinary swimming off a bathing platform is not a scenario in which anything here has any interest in you.
Snorkel gear is aboard on request and costs nothing, and the honest assessment is that Dubai is not a snorkelling destination. The bottom in the usual anchorages is mostly sand, visibility varies from good to poor depending on wind in the previous day or two, and there is no reef in the sense that the Red Sea or the east coast of the UAE has reef.
What there is: fish gathering under the hull almost immediately once the engines stop, occasional rays over the sand, and around the Palm breakwaters and the World Islands some structure that holds more life. On a clear winter day behind the crescent you will see the bottom and a reasonable amount moving over it.
If snorkelling is genuinely the point of the trip rather than a pleasant twenty minutes of it, the honest advice is Fujairah and the east coast, which is a two-hour drive and a different sea entirely. For everyone else the gear is there, it is free, and it is worth ten minutes.
It is worth restating what actually sends people home from a charter unhappy, because none of it is marine life and all of it is preventable.
Yes: whale sharks, blacktip reef sharks and several small bottom-dwelling species live in or pass through Gulf waters off Dubai. All are harmless to swimmers, and shark attacks in UAE waters are effectively unheard of.
Yes. Charters anchor in sheltered spots behind the Palm crescent or among the World Islands, away from shipping lanes. The real hazards are sun, boat traffic and currents rather than marine life.
Occasionally, most often between April and September. They are filter feeders and completely harmless. Sightings are rare enough that crews remember them, so it is not something to plan a charter around.
Occasionally, usually in warmer months and usually in patches rather than everywhere. They are a nuisance rather than a danger. Crews will move the anchorage if a swim stop turns out to be in a patch.
Incidents are effectively unheard of. The Gulf's shallow, warm, highly saline water does not suit the large predatory species associated with attacks elsewhere.
Essentially no. The Gulf is a shallow, almost enclosed basin averaging thirty-five metres, with summer surface temperatures above 33°C and salinity well over ocean average. Large pelagic predators need deep, cooler water and long migration routes.
Sometimes. Indo-Pacific humpback and bottlenose dolphins live along this coast and are most often seen early in the morning and further offshore, so a dawn charter or a fishing trip has a much better chance than an afternoon run.
Almost certainly it is a blacktip reef shark under two metres that is already leaving. Do not chase or corner it, return to the boat calmly if you prefer, and tell the crew, who will usually confirm it has gone rather than move the anchorage.
