Tourist season in Greece is during summer and it starts as early as April (in southern Greece) and May, for the rest of the country. It ends for most people during the first days of September while for some others it goes on till the middle of October. In Crete and Rhodes, tourists season stops only for 4 months a year, from late autumn till the end of winter.
The tourist season is divided in three sections, low, middle and high season (usually mid July till August 20th).
How to choose when to travel to Greece
It all depends on how you want to spend your holidays. Low season (usually from April till the first days of June) is the best time to travel to Greece if you want to spend as little money as possible and enjoy a crowd free holiday. Weather is cooler, beaches are your to enjoy, service is better (less customers to satisfy) and people are more relaxed.
High season is the most expensive of them all but you can still find good quality, affordable accommodation by slightly changing your requirements. This is the period when you will have to share a place at your favourite beach with other people and to wait a bit more to get served at the restaurants and bars. But, you know what some people say: the more the merrier.
If you want a bit of both, then try the middle season. Whenever you decide to travel to Greece, know that it is the beautiful country and its great people that will make your holiday special. Rest assured that if you keep an open mind and explore true Greece, it will be a lot more than a wonderful holiday; it will be a great experience.
