Is It Safe To Swim In The Adriatic Sea In Croatia?

Yes, swimming in the Adriatic Sea in Croatia is regarded as generally safe as long as you take some precautions:
Always gradually enter into the water
Before jumping, make sure it’s deep enough
Many Croatian beaches are rocky or concrete. Some areas can be very slippery
If they’re not rocky, they are made up of pebbles. If you’re unstable, you can twist an ankle. Or worse, be ridiculed.
Waves can be exciting, but treacherous
Sea urchins lurk among the rocks
Swimming too far away from the coastline or outside of the designated beach limits can be highly risky because of water scooters and speed boats
If you fall asleep on a floating air mattress, you will need to get a ferry back from Italy. Or swim back.
