Santorini, surrounded by the vast Aegean Sea, is a wonderful destination for scuba diving. What makes it great are its ideal water conditions: its clear blue water is slightly warm and has a mild current, making it a great choice for beginners. The weather in Santorini is usually warm and pleasant, which is ideal for scuba diving too. Moreover, in addition to the diverse aquatic life, you would see numerous underwater volcanic rock formations as the island is an active volcano along with a shipwreck! There are various 3-4 day open water courses where professional instructors teach you to dive down to about 12m in shallow water. So, if you know how to swim and are ready for this unforgettable experience, go ahead and book your Santorini diving excursion!

Best Time for Diving in Santorini

The weather in Santorini is warm and dry between April to early October, so the water tends to be warmer and calmer with a mild current and thus very conducive for scuba diving. June to August is usually the peak season for tourism and, therefore, for diving. Still, if you want the diving sites to be less crowded, May to June and September are also suitable, although the water is slightly cooler. The period between November to March experiences cold and wet weather conditions, and it is best to avoid diving around this time.

Tips for Scuba Diving in Santorini

  • You have to be over the age of 10 to be allowed to go diving. If you are under 18, you must get parental consent.
  • If it is your first time diving, you must get a medical certificate; the diving centre recommends a local doctor.
  • You must get your Open Water Diver (OWD) licence before diving since it is not only a requirement but also allows you to dive into a depth of up to 18m anywhere in the world. Also, don't forget to get diving insurance.
  • When choosing a day to go diving, it is better to pick a day when the weather would be pleasant, as waves might make the experience slightly harder. 
  • Diving isn't a very physically demanding activity, but you must be healthy and should know how to swim. 
  • When on the boat, listen carefully to your guide to properly understand what you are supposed to do and be aware of where they are when in the water. Also, double-check all your equipment. 
  • Make sure to breathe normally when in the water and to equalise frequently as you descend to avoid any issues with your ears. It is also important to monitor your air gauge.
  • Avoid coming up too fast, as that, too, can cause the bends. 
  • Don't touch anything in the water; you might accidentally touch a sharp or poisonous coral or startle an aquatic creature. Also, ensure you don't fly for at least 24 hours after your dive since you are susceptible to the bends.
Santorini's crystal clear waters boasting warm temperatures, diverse aquatic life, unique volcanic formations, and the surrounding beauty make the island an excellent choice for diving. Whether you are a beginner or a pro-diver, it has a lot in store for you, including deep diving, cave diving, wreck diving and wall diving. So choose the course that appeals to you, put on your suit and explore the island's mesmerising water.
