Winter in Iceland paints a picturesque landscape of snow-covered mountains, icy waterfalls, and the mesmerizing Northern Lights.

Snorkeling in Silfra during winter is not only possible but also an experience of a lifetime. And with the right gear, you won't even feel the cold.

What is Silfra Fissure?

Silfra, a fissure located in the Thingvellir National Park, is one of the top snorkeling destinations in the world. It's the only place you can snorkel between two continental plates, the North American and Eurasian. The glacial water, filtered through underground lava for decades, offers unparalleled visibility of up to 100 meters.

One of the unique aspects of winter in Iceland is the limited daylight, with only 4-5 hours between November and February. Consequently, there are fewer tours available daily compared to the summer months. However, winter also means fewer tourists at Thingvellir National Park and at Silfra Fissure, giving you a more peaceful and personal snorkeling experience. And if you're lucky, the day might end with the mesmerizing dance of the auroras in the sky.

With the possibility to try this experience year-round, it’s definitely one of the best things to do in winter in Iceland. And while winter temperatures might be lower on land, Silfra's water temperatures remain consistent throughout the year, ensuring a stable snorkeling environment.

So, if you're in Iceland for the holidays, bravely book that snorkeling tour to add a touch of magic to your celebrations.

Staying Warm while Snorkeling in Iceland in Winter

The cold is among the most common concerns about snorkeling in Silfra Fissure during winter. After all, the water temperature remains a near-constant 2-4°C (35-39°F) year-round. But fear not! You'll stay warm and comfortable with the appropriate snorkeling gear, even in the chilly waters.

The water temperature in Silfra stays around 2-4°C (35-39°F) all year long.

We understand these concerns, so on our tours, we provide top-quality dry suits specifically designed to keep you dry and warm. These suits come with seals at the neck and wrists, ensuring that the cold water barely touches your skin. The dry suits are also specially designed to float on the water's surface, making it challenging to submerge due to the trapped air. This design not only ensures buoyancy but also keeps you warm. 

While the suit keeps most of your body dry, your hands and head are protected by neoprene, a material designed to heat the water trapped within, providing additional warmth. We also provide essential snorkeling gear, including a diving mask, flippers, and a snorkel.

Underneath the dry suit, it's essential to wear a few layers to ensure you remain warm and insulated, even when damp:

  • Base Layer: Start with thermal underwear and socks. This will be your primary insulation against the cold water.

  • Secondary Layer: Cover your base layer with a layer of fleece for added warmth. Polypropylene is another good option.

  • Avoid Cotton! Cotton retains moisture and can make you feel colder, so avoiding any clothes with cotton when snorkeling in Silfra is best.

* For those who wear glasses, we recommend switching to contact lenses for the best underwater visibility.

Equipping oneself with the dry suit might seem challenging, but our experienced guides are always ready to assist. Their expertise ensures that you are snugly fitted into your suit, maximizing comfort.
