Diving Conditions in Greece

 

Greece is one country, with one proud people inhabiting it. Who use one language and share one history. And who in the vast majority always had a special relationship with one element. The sea.

Diversity

And somewhere here oneness is lost and gives its place to diversity. Diversity. First of all it is not one sea. The Mediterranean, the large ancient sea, is divided by Greece's scattered form of a peninsula surrounded by numerous islands of every possible size. Divided into three large distinct seas, the Aegean, the Ionian and the Libyan. In addition, the extricate pattern of the shoreline forms hundreds of gulfs, bays and coves. So the underwater conditions are different and localized. Which can also be the case as far as the weather is concerned. Local winds and tidal patterns can vary within a day or mile.

The weather in Greece

General speaking, the weather in Greece is trustworthy. This means good. You can bet your dime that it will be sunny the next day, almost all year round. Rainfall is low and snow tends to stay in high mountains. Temperatures can fall in the heart of winter down to 2 or even in the minus zone mainly in the mountains. And we have plenty of them. Mainland temperatures keep mild and when spring time comes heavy clothes go! This makes sure that besides the time from November to mid April, divers will not have to bear nasty wind or cold outside water. It also has an effect on the underwater conditions. Water temperatures vary from 16 to boiling 27 C in recreational depths.

Underwater environment

Thermoclines are generally lower as spring turns to summer. 5mm wet suits are excessively used compared to others in the warmest half of the year and dry suits are reserved for winter holiday diving. September, the sea is at its warmest, down to 30 meters and more.

Rocky "mountainous" terrain on the Greek land is a reflection of the underwater environment as well. Islands and peninsulas can be viewed alternatively as the peaks of underwater walls and descending dive sites full of rock formations. Of course these come along with crevices, caverns and holes as well as clear water springs that glitter with sealife. It is common for divers accustomed to tropical destinations to express their awe for the impressive rugged massive stones that pop out of nowhere in the middle of sandy beaches and the intimidating rocky walls full of algae and sea weeds. However, rocky terrain does not fill the subject and any discussion on diving conditions in Greece cannot but contain a reference of corals.

The warm water of the Mediterranean Sea has not been affected by global warming to a degree that endangers coral reefs as much as other tropical habitats. Corals flourish in bays and shores that have been protected from industrial fishing which in Greece has not been developed. They are often spotted competing with the prolific algae for space.

 

The absence of a major stream in the Mediterranean has two significant consequences for the conditions underwater. First, there are not many or strong currents so drift diving can be limited although coves come in an abundance and cause water movement appropriate for serious fun. The second result is visibility. Less current means less moving nutrients so the water stays clear. You can expect to see clearly in distances of more than 30 meters.

And there is a lot to see. Schools of reef fish swim effortlessly between rocks and precipices which provide protection from predators that raid a site and go on to the next. Pelagic fish are a common attraction and so is a variety of invertebrates. Not to mention that two distinct species of a seal and a sea turtle have chosen these waters as their breeding place.

People have always held Greece connected with ancient history and naval supremacy. And this is true.

A crossroad of sea travel from the vast Caspian to the Middle East and home to naval battles across the ages, more ships have travelled through Greek seas in the passage of time than anywhere else in the world. And since maritime history has failures among successes, wrecks is an integral part of diving in Greece.

Boats and ships of all sizes in various depths have already caught the attention of divers and are home to artifacts as diverse as amphora and machine guns! It is like an impromptu archaeological treasure hunting every time you dive and this makes Greece unique as a diving destination.

Even if wrecks tend to dominate the scene, I would like to close this article with the often overlook able staff. The small stuff. The Aegean and the Ionian Seas have a wonderful collection of nudibranches, crabs, sea horses which can steal the show from the octopi and moray eels.

With their stunning colors and amazing shapes and forms, they remind us of old romantic times when bigger was not always better.

If you bring your own equipment

Water temperatures varies from a max. of 28 degrees in the summer to a lowest of 14 degrees in winter. For deep winter dives, according to your personal sensitivity we recommend a semi-drysuit of 5 mm to 7 mm. Some of our clients even use a drysuit. In the summer a shorty can be enough for shallow dives but for deeper or repetitive dives, a 5mm wetsuit and a hood will fill your needs. Gloves are not really needed. Don't hesitate to contact us when preparing for last minute updates!
