The islands are always a bit cooler than the mainland I think, i'm not sure about the weather in relation to Crete thoughFrom what I understand it's cooler than say, the island of Crete, but it's still warm this time of year. Perfect beach weather!
Also the higher elevation you are on a specific island can make things a bit hotter!! Crete is definitely too hot for me sometimesCrete is further south, so it can get pretty hot. I find the temperature on Corfu to be perfect!
For sure, it depends the time of year.Also the higher elevation you are on a specific island can make things a bit hotter!! Crete is definitely too hot for me sometimes
