Self-guided tour in Croatia, what is the local weather and temperature like?

The current average temperature in Croatia is 18℃ ~ 28℃. Just wear cool and breathable clothes such as cotton and linen shirts, thin long skirts, and thin T-shirts. I went to Croatia with a few travel friends just after the college entrance examination last year. The weather there was really good when we went. We found an agency to make plans for us. We had a lot of fun. They had electronic tour guides for every scenic spot. There are audio explanations, and if there is anything we don’t understand, we will be translated remotely online, which is called Frog Journey.
