While Greece’s islands may be among of the world’s most beautiful, they really are different every month as many things depend on the weather and the tourist crowds. If you ask me, the month of October is probably the best month of the year to visit any Greek island. But what a re the best Greek islands to visit in October? My list has them all.

However, October is always less busy as schools have already opened in most parts of the world and not that many people take holidays.


VERY IMPORTANT TO KNOW:
Which Greek island is hottest in June?
The hottest Greek island in June is Crete. In general, June has very predictable weather and it will be sunny 99.9% of the times with very nice summer temperatures but Crete overall is the warmest of all the Greek islands or even mainland Greece. The main reasons for that is that Crete is the most southern island in Greece and it’s basically facing Africa. You should also know that Crete is also hotter than other Greek islands in July and August.Is June a good month to visit Greece??
June is the best month to visit Greece and the Greek islands because the weather is great for swimming and most of the islands and the most famous places in Greece will be less crowded with tourists. June is basically the start of the high season and prices can also be lower in accommodation, ferry, and plane tickets. You should also know that Greeks very rarely go on holidays in June (apart from the June long weekend of Holy Spirit Bank Holiday) which makes things even better in terms of available rooms and hotels.
How busy is Greece in June?Greece is quite busy in June but it is less busy than in July and August, so June is a great month to visit if you are not looking to be in a very quiet place and also being able to enjoy the sunny summer weather of Greece. However, the most famous islands such as Santorini and Mykonos can still feel quite busy in June because they have a longer touristic season. Any other islands than these 2 would feel very relaxing and quiet in June (always compared to July and august of course)
Is it warm enough to swim in Greece in June?
You would be able to swim in Greece in June because the seawater would still be warm enough. The ambient temperature during the day is usually between 25-35 degrees C and it will be sunny pretty much every day. June is perfect for holidays in the summer because there won’t be that many people even on the best beaches in Greece.

Mykonos is the second most famous Greek island after Santorini and they are both very unique but different islands (you can read my detailed comparison of Mykonos vs Santorini). Everything that I mentioned above in regards to visiting Mykonos in June, applies to Mykonos as well. However, Mykonos is also a famous party island and June is the month when most Greeks go to party for the Holy Spirit Bank holiday (around mid-June usually). Also, June is the month when most students in Greece go for holidays so it might be slightly busier but it will still feel empty compared to July and August.
3. Naxos

CONCLUSION
So, these are the best Greek islands to visit in June. I truly believe that June is a great month to visit Greece and the Greek islands but September is also a great month. in June you can definitely go swimming and the islands, in general, will be more quite. The busiest months for the Greek islands are July and August and these are also the most common months for Greeks to go on holidays so everything will be more expensive (accommodation, ferry tickets and even restaurants). If you are planning to visit Santorini or Mykonos in June, try to make it the first half of the month as they would definitely feel less busy. June is still considered high season for these two islands so the earlier the better. On the other hand, if you are looking to meet more people and party then you should definitely visit in July and August.
