Diving in Turkey: Your Complete Drysuit Guide

Turkey sits at the junction of three seas, each with its own character, temperature profile, and diving opportunities. The Mediterranean coast draws holiday divers with warm water and ancient ruins. The Aegean offers wreck diving and dramatic underwater topography. The Black Sea is a world apart — cold, dark, and home to some of the best-preserved ancient wrecks on the planet.

Whether you need a drysuit in Turkey depends entirely on where and when you dive.

Turkey’s Diving Regions

Mediterranean Coast (Antalya, Kas, Kemer, Fethiye)

Turkey’s Mediterranean coast is the most popular diving destination in the country. The water is warm by European standards, the visibility is excellent, and the coastline is dotted with dive centres catering to every level.

Water temperatures: Summer (June to September) sees surface temperatures of 24 to 28 degrees Celsius. Spring and autumn sit between 18 and 23 degrees. Winter drops to 15 to 18 degrees at the surface, with deeper water cooling further.

The Mediterranean coast offers reef diving, wall diving, and a growing number of artificial reef sites. Kas, in particular, has established itself as a serious diving destination with canyon dives, cavern systems, and the famous Uluburun area.

Drysuit recommendation: A wetsuit handles Mediterranean diving from May through October for most recreational divers. From November through April, a drysuit becomes increasingly attractive, particularly for repetitive diving or anything beyond a single recreational profile. Technical divers working deeper sites will appreciate a drysuit year-round.

Aegean Coast (Bodrum, Kusadasi, Canakkale, Gallipoli)

The Aegean coast is cooler than the Mediterranean and offers distinctly different diving. The historical density of the region means wrecks from multiple eras — ancient Greek and Roman vessels, World War I warships, and modern cargo ships — lie scattered along the coast.

Water temperatures: Summer reaches 21 to 25 degrees Celsius at the surface. Spring and autumn range from 15 to 20 degrees. Winter drops to 12 to 16 degrees, and below the thermocline, temperatures can fall into single digits.

Gallipoli deserves special mention. The Gallipoli peninsula’s underwater landscape includes World War I wrecks from the Dardanelles campaign — transport ships, warships, and submarines. These dives are deeper, cooler, and carry significant historical weight. The water here is influenced by currents flowing from the Black Sea through the Dardanelles, making it consistently cooler than open Aegean sites.

Drysuit recommendation: A drysuit extends your Aegean diving season significantly. From October through May, water temperatures make a drysuit the more comfortable and safer choice. For Gallipoli wreck diving, a drysuit is standard equipment year-round among serious divers.

Black Sea Coast (Sinop, Trabzon, Istanbul Strait)

The Black Sea is Turkey’s cold-water frontier. Low salinity, limited light penetration, and cold temperatures create an environment that preserves organic material far better than the Mediterranean. Ancient shipwrecks have been found with timber hulls and cargo intact at depths where oxygen-poor water prevents biological degradation.

Water temperatures: Summer surface temperatures reach 18 to 22 degrees Celsius in coastal areas. Below the thermocline — which can be as shallow as 20 metres — temperatures drop to 8 to 10 degrees year-round. Winter surface temperatures fall to 6 to 10 degrees.

The Black Sea’s anoxic layer, beginning at around 150 metres, has preserved wrecks dating back thousands of years. While these extreme depths are the domain of ROVs and specialist expeditions, accessible wreck diving in the 20 to 50 metre range still involves cold, dark conditions that demand proper thermal protection.

Drysuit recommendation: A drysuit is essential for Black Sea diving. No exceptions. Even in summer, the water below the surface layer is cold enough that extended diving without a drysuit is unsafe.

Wreck Diving in Turkey

Turkey’s wreck diving is a major draw, and it is worth addressing separately because wreck diving changes the equipment equation regardless of temperature.

Gallipoli wrecks: The Dardanelles campaign left a significant number of vessels on the seabed. HMS Majestic, the Lundy, and several French and Australian vessels lie in waters ranging from 10 to 40 metres. The water is cool, visibility can be limited, and the historical significance of the site demands respectful, well-planned diving. A drysuit provides the thermal margin and physical protection that these dives require.

Sunken cities of the Aegean: The coastline around Kas and Kekova includes partially and fully submerged ancient settlements. While much of this diving is shallow, the rocky environment and extended exploration times make a drysuit practical for divers spending full days working these sites.

Bodrum wrecks: The waters around Bodrum include both ancient wrecks and modern casualties. The deeper sites, particularly in autumn and winter, are firmly in drysuit territory.

Choosing a Suit for Turkish Conditions

Turkey’s range of conditions means your suit choice depends on your primary diving location.

Mediterranean-focused divers can choose based on the same logic as any warm-to-temperate water destination. A standard trilaminate with Cordura reinforcement handles the conditions well. Lighter undergarments work for summer, with the option to layer up for winter.

Aegean and wreck divers benefit from reinforced suits. Wreck environments involve contact with corroded metal, rocky substrates, and confined spaces. Cut-resistant reinforcement panels earn their place on these dives. The Ninja, with its Ceramic/Cordura upper body and Kevlar/Silicone lower body, handles both the abrasion of wreck diving and the salt-water exposure of the Aegean.

Black Sea divers need a suit that handles genuine cold. Heavier undergarments, reliable seals, and durable construction matter here. The Kryptonite and Stone suits, which are optimised for cold-water environments, are well-suited to Black Sea conditions where salt concentrations are lower and UV exposure is less intense than the Mediterranean.

Getting an Ugly Fish Drysuit in Turkey

Sealachi distributes Ugly Fish custom drysuits to Turkey. Every suit is made to order in Italy from the diver’s exact measurements, so there is no need to compromise on fit — whether you are based in Istanbul, Antalya, or anywhere else in the country.

Custom fit matters particularly for drysuit diving because an ill-fitting drysuit creates drag, traps excess air in the wrong places, and makes buoyancy control harder than it needs to be. A suit built to your measurements eliminates these problems from the start.

Ordering is handled remotely through Sealachi, with measurement guidance provided to ensure an accurate fit. For servicing, common maintenance tasks can be discussed and coordinated through Sealachi’s support channels.

Frequently Asked Questions

Do I need a drysuit for summer diving in Antalya or Kas?

For recreational single-tank dives, most divers are comfortable in a 5mm or 7mm wetsuit during summer. If you are doing multiple dives per day, diving below 30 metres, or planning any technical profiles, a drysuit offers a meaningful advantage in comfort and thermal management even in summer.

Is the Black Sea safe for recreational diving?

The upper layers of the Black Sea are diveable, and there are established dive sites along the Turkish coast, particularly around Sinop and the Istanbul Strait. However, conditions are demanding — cold water, limited visibility, and strong currents in places. A drysuit, proper training, and local knowledge are essential.

Can I use the same drysuit for Mediterranean and Black Sea diving?

Yes. A trilaminate drysuit works across all temperature ranges. You adjust your thermal protection by changing undergarments — thin layers for Mediterranean summer, heavier fleece or thermal undersuits for Black Sea conditions. One well-chosen suit covers all of Turkey’s diving regions.

What material suits are best for Gallipoli wreck diving?

The wreck environment calls for cut and abrasion resistance. The Ninja or Kryptonite provide excellent protection against jagged steel and corroded metal. Given that Gallipoli’s water is relatively cool and less salt-heavy than the open Mediterranean, either suit handles the conditions well.

How do I order a custom drysuit from Turkey?

Sealachi handles Ugly Fish drysuit distribution to Turkey. Contact Sealachi directly to discuss your requirements, choose your suit model and options, and arrange measurements. The suit is then built to your specifications in Italy and shipped to you.
