Crete has a growing scuba diving scene, with established dive centres along the north and south coasts. The water is warm from June through October, visibility is generally excellent, and there are sites suitable for beginners through to experienced divers.
Conditions
Water temperature peaks at around 26–27°C in August, dropping to around 20°C by October. Visibility is typically 15–30 metres in calm conditions. The Cretan Sea (north) and the Libyan Sea (south) have different characteristics — the south tends to be calmer.
Dive sites
Around Chania
Several operators in the Chania area offer dives from the harbour or boat-based sites along the west coast. The area around the Akrotiri peninsula has accessible sites with reasonable marine life.
Elounda and Spinalonga area
The water around Spinalonga island and the Mirabello Gulf in eastern Crete is among the clearest on the island. A number of dive operators are based in Elounda and Agios Nikolaos.
South coast (Plakias, Agia Galini)
The south coast generally has calmer, warmer water in summer. Dive operators in Plakias offer both beginner dives and guided boat dives to sites along the south coast.
Rethymno area
Dive operators in the Rethymno area offer courses, guided dives and boat trips. The area around Bali has reasonable diving from small coves.
Choosing a dive centre
All legitimate dive centres in Greece are licensed by PADI, CMAS or SSI. Check that any centre you use displays its certification and insurance documentation. In EU waters, all operators must meet specific safety standards.
Important: Crete Guide has not personally evaluated individual dive centres. Always read recent independent reviews and verify certification before booking.
Note on archaeology
Greek waters contain archaeological sites. Removing anything from the seabed is illegal and treated seriously. Photography of ancient objects is generally fine; removal is not.
Beginner options
Most dive centres offer introductory dives (no certification required) for first-time divers, typically to around 5 metres depth in controlled conditions. Full open-water certification courses are available at many centres, usually taking 3–4 days.
Practical notes
- Book dive centres in advance in July and August.
- Some sites require boat access — check what is included in your booking.
- Bring proof of certification if you are a qualified diver.
- Check weather before boat-based dives — the north coast can become choppy in afternoon winds.
