Diving Dhiffushi: dive sites, snorkelling and seasons

The house reef

The house reef is a walk-in snorkel from the beach, with no booking needed. It is shallow near the shore and good for children and nervous swimmers. Parts of it are patchy, so treat it as a warm-up. Stay well away from the harbour and boat lanes, never snorkel alone, and check the current before swimming out to the edge.

Boat trips

For healthier coral, turtles, rays and sharks, take a boat. Half-day snorkelling trips usually combine two or three stops, such as Coral Garden or a turtle reef. Divers usually do morning and afternoon boat dives. Longer full-day trips go further afield for mantas and whale sharks.

Depths and levels are approximate; your guide picks sites to suit the day’s current and weather.

Other sites include Stairs, a stepped reef with ledges, and West Rock Wreck, a small wreck at around 10–26 m. Famous North Malé classics such as Banana Reef, HP Reef and Lion’s Head are offered as longer trips when enough divers sign up. See all sites and the island’s dive centres on the diving page.

• North-east monsoon (roughly December to April): usually calmer seas and the clearest water, often 30 m or more. Channel sites like Colosseum are at their best, with currents flowing into the atoll.
• South-west monsoon (roughly May to November): more plankton, more rain and wind, and visibility nearer 10–20 m. This is manta season on Dhiffushi’s side of the atoll, at Manta Bay and the One Palm cleaning station.

Whale sharks are a separate trip. They live year-round in the South Ari Marine Protected Area, about 82 km from Malé, with the most sightings from about August to November. From Dhiffushi it is a long day out; see the whale shark and manta trip. The sea stays around 29°C all year, so a thin wetsuit or rash vest is plenty.

Dive centres on Dhiffushi generally teach under PADI or SSI. Typical options are:

• Try Scuba / Discover Scuba: a supervised first dive, no certificate.
• Open Water: usually three to four days, with theory, confined water and four open-water dives.
• Advanced and specialities: deep, navigation, Nitrox and similar, often with fun dives counting towards them.
• Refresher: worth booking if you have not dived for a year or more.

If you are already certified, bring your card (or app) and logbook. Maldivian law asks divers to show certification and recent experience.

Treat these as rough guides from 2025–2026 listings, not quotes:

• Single boat dive: commonly about USD 45–70 on local islands, often less per dive in packages.
• Open Water course: roughly USD 475–800, depending on whether accommodation is bundled.
• Snorkel trips: turtle reef trips about USD 30–45; nurse shark trips about USD 40–130.
• Whale shark and manta day trip: around USD 150 per person, meals included.

Ask whether equipment hire, Nitrox, boat fees and taxes are included.

Maldivian diving regulations set firm limits. Recreational dives must stay above 30 m, no decompression dives are allowed, operators must be licensed and solo diving is not permitted. Many centres also require each diver to wear their own dive computer.

Channels and outer reefs can have strong currents, so you will often drift. Listen to the briefing, stay with your guide, and carry a surface marker buoy. On a local island, cover shoulders and knees when walking from the beach or harbour back through the village.

Choosing a safe operator

Ask a few simple questions before you book:

• Are you licensed by the Ministry of Tourism, and can I see it?
• How many divers per guide, and are groups split by experience?
• Is there oxygen and a first-aid kit on every boat?
• What is your emergency plan, and which recompression chamber would you use?
• When was the equipment last serviced?
• Do you cancel or change sites when the sea is rough?

Several famous sites near Dhiffushi, including Banana Reef, HP Reef and Lion’s Head, are protected areas. Rays, including mantas, have been legally protected in the Maldives since 2014.

• Never touch, chase, ride or feed any animal, and avoid trips that use food to attract sharks or rays.
• Keep at least 3 m from mantas and 3–4 m from whale sharks; do not swim above them or block their path.
• No flash close to their eyes.
• Keep fins off the reef, never stand on coral and take nothing away.
• Wear a rash vest and reef-safe sunscreen.

Free evening stingray watching from the beach follows the same rules.

Divers Alert Network suggests waiting at least 12 hours before flying after a single no-decompression dive, and at least 18 hours after several dives or several days of diving. Most people plan their last dive the day before departure.

The island’s health centre handles first aid and minor injuries; serious cases go to Malé. Dive centres on Dhiffushi use the hyperbaric (recompression) unit at ADK Hospital in Malé, which opened in 2023 and is reached by speedboat. Your dive centre should know which it would use. For any emergency on the island, call the police on 119. Travel insurance that clearly covers scuba diving and medical evacuation is essential.

• Certification card, logbook and dive insurance details
• Your own mask and dive computer, if you have them
• Rash vest, reef-safe sunscreen, hat and sunglasses
• Seasickness tablets for longer boat trips
• A dry bag, towel and a light cover-up for the village
• Cash in US dollars or rufiyaa; the ATM on the island accepts foreign cards
