Diving in Turkey in December

Conditions in December

So, you're dreaming of diving in Turkey in December? Let's get real about what you can expect. While Turkey offers some truly stunning diving experiences, December is undeniably the off-season. This isn't your typical balmy Mediterranean dive holiday. The weather topside can be quite chilly, with average air temperatures ranging from 5°C to 15°C (41°F to 59°F), especially in coastal areas known for diving like Kas and Fethiye. You'll definitely want to pack warm layers for surface intervals and evenings.

The sea state in December can be unpredictable. While you might get lucky with calm, sunny days, it's also common to encounter choppier conditions, particularly on more exposed dive sites. This can lead to some dive cancellations or changes in itinerary, so flexibility is key. Water temperatures are on the cooler side, typically ranging from 16°C to 19°C (61°F to 66°F). This is certainly not bathwater, so proper thermal protection is essential. Visibility, however, can often be excellent during this time, frequently exceeding 20 meters (65 feet) and sometimes even pushing 30 meters (98 feet) on good days, as there's less plankton bloom compared to warmer months. Currents are generally mild to moderate, though local conditions can always vary, especially around headlands and islands.

To put it bluntly, diving in Turkey in December isn't for the faint of heart or those seeking tropical warmth. Most dive centers and liveaboards significantly reduce their operations or close down entirely for the winter break. However, for the hardy and adventurous diver, it can offer a unique, uncrowded experience, albeit with cooler temperatures and potentially less consistent weather. You'll find a quieter, more peaceful atmosphere both above and below the water, which can be a real draw for those looking to escape the crowds of peak season.

What you will see

If you brave the cooler waters of Turkey in December, you're in for a treat of a different kind than the summer months. While large pelagic sightings like manta rays or whale sharks are not typically associated with Turkish waters in general, and certainly not in December, you can still encounter some fascinating marine life. The cooler temperatures actually bring certain species closer to shore and can make for some excellent macro opportunities. Look closely, and you'll find an abundance of nudibranchs of various species, often more active in the cooler water. Scorpionfish, moray eels, and octopus are frequently spotted residents, often tucked into rocky crevices and shipwrecks.

December can offer interesting sightings of migratory fish species as they move through the Mediterranean. You might encounter schooling barracuda, amberjacks, and even the occasional tuna, though these are more common in deeper, open water areas. Keep an eye out for groupers – these magnificent fish are often seen patrolling the reefs and can be quite curious. The general reduction in human activity also means that some shyer species might be more visible. You'll likely see plenty of colorful wrasse, blennies, and gobies flitting around the seagrass beds and rocky reefs. Don't forget to explore the fascinating topography, which often harbors a diverse array of invertebrates.

While December won't boast massive aggregations of specific species like some other world-renowned dive destinations, the real beauty lies in the detailed observation of the resident marine life and the sheer tranquility of the underwater world. It's an excellent time for underwater photographers who enjoy macro subjects or capturing the pristine clarity of the water against the intricate rock formations. You might even spot an occasional loggerhead sea turtle, although they are less prevalent than in warmer months. The focus here is on the subtle, the smaller, and the serene, making it a very rewarding experience for the attentive diver.

Top dive sites this month

Given the limited operations in December, your best bet for consistent diving opportunities will primarily be centered around a few key regions. Kas, on Turkey's Mediterranean coast, is arguably your best option. Its sheltered bays and numerous dive sites mean that even on choppier days, there's usually somewhere diveable. "Canyon & Wall" is a classic Kas site that offers dramatic topography and often excellent visibility. Here, you can explore a stunning canyon leading to a deep wall, often frequented by groupers and schooling fish. Nearby "Flying Fish Reef" is another excellent choice, known for its healthy Posidonia seagrass beds and resident marine life, providing good shelter when conditions are less than perfect.

Further east, the area around Fethiye, particularly the dive sites accessible from Oludeniz, can also offer some limited diving opportunities, though it's less consistent than Kas in December. "Afkule Cave" is a visually stunning dive, a large underwater cave with beautiful light shafts and often excellent visibility. While not exactly a "reef" dive, the experience of exploring such a dramatic cavern is unforgettable. However, access to this and other exposed sites will be highly dependent on sea conditions. For those willing to accept cooler water and potential weather-related changes, these regions provide the most reliable access to Turkey's underwater wonders in the depth of winter.

Practical tips for your trip

Diving in Turkey in December definitely requires some specific preparation. Firstly, wetsuit thickness is crucial. We highly recommend a 7mm semi-dry wetsuit at minimum, or ideally, a drysuit if you have one and are certified to use it. Many divers also opt for a hooded vest, gloves, and booties to maximize thermal protection. Remember, multiple dives a day in cool water will chill you quicker than a single dip. This month is generally best suited for more experienced, cold-water tolerant divers. While some dive centers might still cater to beginners, learning to dive in cooler water can be less comfortable and potentially more challenging, so it's not ideal for a first-time experience.

Liveaboard availability in December is extremely limited, if not entirely nonexistent. Most liveaboard operators in Turkey suspend their operations for the winter season. Your diving will almost certainly be shore-based or day-trip based from local dive centers that choose to remain open. It's absolutely essential to pre-book and confirm with dive centers well in advance to ensure they are operating and can accommodate you. Don't just show up expecting to find a dive shop open. What to pack? Think layers! Warm jumpers, a waterproof and windproof jacket, hats, and gloves for topside are a must. Also, pack a warm robe or a dry change of clothes for after-dive comfort.

Things to be aware of: Reduced services overall. Many tourist-oriented businesses, restaurants, and hotels in popular dive towns like Kas will either be closed or operating on reduced hours. While this makes for a quieter experience, it also means fewer options for dining and entertainment. Embrace the local culture and seek out places favored by residents. Always have backup plans for your diving, as cancellations due to weather are a real possibility. Prepare for a more rustic, less resort-focused experience, and you'll find that diving in Turkey in December can be a truly rewarding adventure for the intrepid diver. Just be prepared for the chill!
