Black Sea – located in the SE of Europe, is a unique environment that despite its name, is quite diving friendly. Well… is not quite the Red Sea or the Mediterranean Sea, but for sure, is beautiful! In the next chapter, I will talk a bit about SCUBA diving in the Romanian Black Sea coast sector with which I am familiar. Other Black Sea coastal areas might have similar or different particularities. Contact a local dive center(s) for collecting the right and up-to-date information.

We are diving the Black Sea all year round. Anyway, the preferred season is beginning summer – half autumn, starting sometime in June and ending sometime beginning of October. With plus/minus.

Weather & winds: Unfortunately, everything is related to the weather, respectively to the wind direction.

In the north part of our coastline is the Danube Delta and everything else is south of it, and with the predominant wind from NE which blows down all the muddy water, the visibility is heavily affected by the weather. Danube Delta is a UNESCO Heritage – a fabulous place to visit, approx 140Km North of Constanta.

When winds blow from the South, clear and cold water is brought from the deep waters of Bosporus, and visibility is greatly increased.

And one more thing… there are no big bays or islands to break down the winds or currents. So… better have your passport in your hands, just in case. Just kidding!

Also, another characteristic of the Black Sea is that… is very moody! We need a large window of good weather ahead to go out at sea. Websites such as Windguru & Windy are constantly monitored, as well as marine VHF channel 25 for last-minute weather reports. We had dives when the sea status changed even in one hour from flat to choppy.

Visibility: average: 5…8m. Extremes: -0.5 to +20mtrs. 5m is decent and has good visibility to enjoy any dive. Black Sea dive!

Water temperature: from +4degC in the winter to +27degC in the summer (surface) with strong thermocline anywhere below -10m…-15m down to 8-10deg C. So in the summertime is very common to have a 15-20deg C difference between surface and bottom.

This requires the diving plan to be well-executed, teamwork and coordination, otherwise overheating in the drysuit is not a good idea.

Warm water comes with lots of plankton and vegetation. Which drops the visibility. Not so friendly for underwater video photographers.

Salinity: Black Sea salinity is very low, almost like freshwater. Excellent for “out of mask” situation 😊and bit less weight ballast 😃 Plus that we use Steel cylinders for backmount, Aluminium cylinders for sidemount.

Wrecks: our area of expertise! We love wrecks, we dive wrecks, and we know wrecks inside and outside. With +30 years of sea experience, we embedded in our DNA & breathe ships & wrecks!

An excellent description of the Black Sea wrecks accessible in our area can be found here: https://www.blackseawrecks.ro/

Best ones: are the warship Russian destroyer Moskva and the two Russian submarines (SC-213 & Malyutka XII).

In some wrecks, penetration is possible, of course, with proper qualification, team & gear. For wreck diving training – You Xiu, Sadu, and Paris are offering excellent profiles in depth and complexity.

Depths: from -22m to -45m. We require for all divers to be qualified minimum Advanced Open Water + Basic Nitrox and for some wrecks (over -35… -38m) – a minimum TDI Deco Procedures, ANDI Technical SafeAir Diver L3 or equivalent. This is due to the distance from the safe haven combined with the harsh conditions (thermocline, currents, visibility) as we try to minimize any possible reason for an unwanted event.

Diving insurance: compulsory. If you don’t have a valid one, we can assist you.

Medical fitness: all divers are required to be in a minimum decent physical shape! Overweighted and under influence of alcohol or drugs – not accepted. We do not support smokers therefore, we suggest you refrain from your unhealthy habit for the duration of our activities. The new medical form must be filled up and signed by all participants.

HBOT: in Constanta, we are proud to have a private high-class medical facility with a qualified team, in case of emergency and also, for regular check-ups or specialized medical examinations.

Sealife: quite rich I can say, depending on the season. Sea horses, pipefish, gobies, crabs, jellyfish, all sorts of local fish, even stingrays, and sometimes, dolphins.

Underwater archaeology:

• Sunken city Tomis: Dive into history! Max depth: -6m to -8m.

Easy dives but very interesting site, good for training and check/try/refresh dive, rich in sea life and history!

• Callatis: presently Mangalia city, located approx 40Km South of Constanta. Depth: -3m to -9m.

Facility & logistics: we do and/or have:

• gases: air, EANx, O2 up to TMX.
• TEC booster 220/2
• technical space for basic fixing gear
• Logimec ultrasonic cleaner
• bathroom, free wifi.
• DAN Emergency Oxygen kit & (real) AED
• provide a wide range of training for Sport & Technical, First Response,
• Personal Doppler (O’Dive) analysis
• CCR (JJ-CCR & SF2 eCCR) & Disability-friendly!

Diving Boats: we have 4 charter options:

• brand new Open 22 Turist – “Nautilus”- 6.5m length, 2.5m wide with 14oHP outboard Suzuki – owned by Nautilus-Diving.EU

• brand new Jeanneau Cap Camarat 7.5mtrs – “Lybra”- owned by – ScubaOne®

• One large vessel (up to 25pax) – slow(er) speed, only for coastal diving. Good for large groups, even small parties onboard 😊
• One diving boat, approx. 15m length, up to 8-10pax, good for offshore diving.

Accommodations and restaurants:  Constanta city is full of hotels, motels & restaurants for all budgets.

Traveling to Constanta:

The main Romanian airport in Otopeni, Bucharest (OTP) – approx. 250kms distance, shuttle (mini) busses/ cars or trains available.

The local airport (international) – Kogalniceanu (CND) – is just 25kms distance from Constanta city.

Train station: approx 3km distance from our location.

To visit: Histria, Adamclisi – historical places. Murfatlar is a great place if you like some good wine. Good restaurants in the city with traditional and international cuisine. Rich nightlife in Mamaia Resort, just north of Constanta with a great beach (very recently extended!) with lots of night party clubs.

South of Constanta – a dozen large resorts are offering all kinds of entertaining for day and night visitors.

Danube Delta – the 2nd largest river delta in Europe – has lots of options to explore the rich, beautiful & unique life with various local providers, including extended cruises with MS Diana.

Techirghiol – another famous place, very well known for its therapeutical mud!

Covid19: this is as you know, an ongoing situation. We try to comply as much as possible or exceed regulations, when possible (including UV lamp for example), but we need to keep eye on the local and international movements as things might change at the last minute

Other diving locations in Romania: caves (Isverna), mines, and lakes.

Latest updates: as of April 2021, any recreational diving activity is under surveillance and control of the Romanian Navy Dive Center. Unfortunately, the totalitarian monopoly of a governmental military institution with NO international accreditations, experience, training, standards, or knowledge of any kind of our recreational/technical diving activities is coming with a heavy negative impact on our businesses. At this moment, the APSR (a private NGO of Romanian professional recreational divers) is in discussions with high governmental institutions in order to clarify and establish a professional relationship between recreational/technical divers and other parties.

As such, most of our activities will be temporarily re-design, including for overseas training and activities. Will keep you updated!
