Hi I have heard that the water temprature is not too comfortable for swimming in May. Can someone please confirm and I would like to visit there in late May and would not want to go there if I can't swim. Thanks for your time in reponding
My wife and I have gone twice in late May. We are both from Los Angeles and have spent much time in the water here. In late May I found the water around Greece to be warmer than Southern California is in July or August. I think you will find it refreshingly cool as long as the weather is good to you.
Have a great trip,
