The beautiful, warm weather all year around in Greece lends itself for the perfect destination for everyone. No matter what season your calendar is showing, its mild climate along with the picturesque locations can make it be an escape for anyone trying to avoid the hustle and bustle of the peak season. The end of September is somewhat of a transitional period in terms of tourism.
