Best Greek Islands to Visit in September

Wondering what’s the perfect month to visit the Greek Islands? Depending on your needs, September might be the best answer. Below, you can find a list of the best Greek Islands to visit in September!

Why visit the Greek Islands in September?

Unlike the high season, meaning July to August, September is a hot month that can offer some cooler temperatures during its duration depending on the time of the day. The average temperature in coastal places of Greece during September is 25° and the weather is mostly sunny, ideal for beach hopping, and great for outdoor activities, from sightseeing to active hiking.

September is considered high season, from mid to end September, most islands consider it off-season, so the prices tend to be lower and the accommodation options vast during that period. You will surely find some large crowds in the most popular destinations even in September, but there’s no comparison to the high season and especially the 15th of August which is a national holiday and religious celebration.
