Sea temperatures in Croatia
June - the month when the sea heats up
In June, though, warms up at a slower rate so for many tourists it’s still too cold at 17-18 degrees. But the local population typically have no problems with that. They also have a desire to show their bravery to everyone by going into somewhat colder water. In June, the sea temperatures climb above 20 degrees and become nice for swimming. In July, they climb a couple more degrees higher on average.
August - the sea is like a nice bath
The sea is the warmest during August. The average sea temperature in August is mainly around 24 degrees, but during the day it can climb to 27-28 degrees.
In September the sea temperature gradually begin on a downhill path, but given the fact that they cool down at a slower rate, they’re still above 20 degrees. Only in October do they drop below 20 degrees on average and arrive to the levels seen in May.
That’s when the swimming season ends on the Croatian coast. To conclude - if you’re coming to Croatia this summer in June, July, August or September, you won’t go wrong.
