Greece’s climate changes significantly throughout the year, so you should plan your visit around your preferred weather.
The summer is the peak season for Greece tours because that’s when the weather is warmest. That also means you have to deal with large crowds if you visit during the summer, which isn’t ideal for everyone.
The shoulder seasons — spring and autumn — are a better time to visit if you want to avoid traffic. While the weather isn’t quite as warm as it is during the summer, visiting in the spring or autumn gives you an opportunity to enjoy a more authentic Greece vacation.
