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


The best Greek islands to visit in June are:

Which Greek island is hottest in June?
The hottest Greek island in June is Crete. June has very predictable weather, and it will be sunny 99.9% of the time with very nice summer temperatures, but Crete is the warmest of all the Greek islands or even mainland Greece.
The main reason is that Crete is the southernmost island in Greece, and it faces Africa. You should also know that Crete is 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 the start of the high season, and prices can also be lower for accommodation, ferry, and plane tickets. You should also know that Greeks rarely go on holidays in June (apart from the long weekend of the Holy Spirit Bank Holiday in June), which makes things even better regarding 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 be 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 tourist season. Any other islands than these two 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 can swim in Greece in June because the seawater is still warm enough. The ambient temperature during the day is usually between 25 and 35 degrees C, and it will be sunny almost daily. June is perfect for summer holidays because there won’t be many people, even on the best beaches in Greece.

1. Santorini
- Santorini on Google Maps
- Best Hotels in Santorini: Maregio Suites • Grace Santorini • Cosmopolitan Suites
You will enjoy Perissa Beach (Black Beach), Kamari Beach, and Vlychada Beach, as well as the famous and unique Red Beach with fewer crowds. However, visit Santorini in the first half of June if you can.
The weather would be the same, but it would be even less busy. June is also a great month for your honeymoon in Santorini.
2. Mykonos

- Mykonos on Google Maps
- Best Hotels in Mykonos: Cavo Tagoo • Bill & Coo • Grace Mykonos • Rocabella Mykonos
Mykonos is the second most famous Greek island after Santorini. They are both unique but different islands (you can read my detailed comparison of Mykonos vs. Santorini). Everything I mentioned above regarding visiting Mykonos in June also applies to Mykonos.
However, Mykonos is also a famous party island, and June is the month most Greeks go to party for the Holy Spirit Bank holiday (usually around mid-June). Also, June is when most students in Greece go on holiday, so it might be slightly busier, but it will still feel empty compared to July and August.
3. Naxos
- Naxos on Google Maps
- Best Hotels in Naxos: Belogna Ikons • Naxian Utopia • Nissaki Beach Hotel
4. Crete

- Crete on Google Maps
- Best Hotels in Crete: Domes Noruz • Creta Maris Beach Resort • Caramel Grecotel
Crete is the largest Greek island, and it never feels busy, to be honest. It is one of the hottest places in Greece, and you will get the best weather if you visit in June. It won’t be unbearably hot, and the sea waters will be warm enough for swimming.
5. Corfu
- Corfu on Google Maps
- Best Hotels in Corfu: Corfu Imperial Grecotel • Bella Venezia • Lena Mare Boutique Hotel
6. Skiathos

Skiathos is a little gem in the Aegean Sea, but it’s north of the Cyclades islands and belongs to another group of islands called the Sporades. Skiathos will have great summer weather in June and be warm enough to swim in its beautiful beaches.
7. Milos
- Milos on Google Maps
- Best Hotels in Milos: Volcano Luxury Suites • Arco Solium • Milos Resort
Milos would be even better in June, but in general, even in August, Milos is great. The best thing you can do in Milos is a boat cruise to the incredible Kleftiko Coves.
8. Ios

- Best Hotels in Ios: Hide Out Suites • Ios Palace • Relux Ios
9. Paros

- Paros on Google Maps
- Best Hotels in Ios: Yria Island • Calme Boutique Hotel • Seesoo Paros
Paros island is in the Cyclades group of islands, and it is extremely busy with Greeks and non-Greek visitors in July and August. That’s why June is the perfect month to visit the island of Paros without being overwhelmed by the crowds in the picturesque little towns of Paroikia and Naoussa.
10. Kefalonia
- Kefalonia on Google Maps
- Best Hotels in Kefalonia: Avithos Resort • Costa Azzurra • Fiscardonna Suites
11. Zakynthos

Zakynthos is an island close to Kefalonia and Corfu, which is usually very busy in July and August, but June is pretty relaxed and quiet.
CONCLUSION
So, these are the best Greek islands to visit in June. June is a great month to visit Greece and the Greek islands, but September is also great. In June, you can go swimming and the islands, in general, will be quieter.
The busiest months for the Greek islands are July and August. These are the most common months for Greeks to go on holidays, so that everything will be more expensive (accommodation, ferry tickets, and even restaurants).
If you plan to visit Santorini or Mykonos in June, try to make it in the first half of the month, as they will feel less busy. June is still considered high season for these two islands, so the earlier the better. On the other hand, if you want to meet more people and have a party, you should visit in July and August.
