Prices are low, nothing is crowded and the weather is pleasant. Plenty of events and festivals to enjoy the best fall in Greece.
The weather is pleasant but can get cooler by the end of the month. The trend, however, is to have quite warm weather in October so don’t worry about the weather being too cold. It’s worth it to check the forecast bit in advance though. On the islands it’s quite windy.

Due to winds the water transportation is often disturbed. The seasonal ferry routes are closed and so are most of the hotels and restaurants on the islands. Some of the domestic flights are also cut back. Prices are moderate to low and your best bet is to visit the mainland. The capital and Thessaloniki are served by regular international flights but it is advisable to check the schedule.
Things to do
There are plenty of local events and fairs to enjoy in October. The parade on Ochi Day (October 28) is an important event which makes traffic stop and businesses close for the day (including most archeological sites). Coastal cities usually have naval parades on this special day. Ochi Day is the anniversary of General Metaxas’ denial to the Italians’ request for free passage to invade Greece. His denial brought Greece into the war on the Allied side.
The celebration is even more important in Thessaloniki: the city celebrates its patron saint, Saint Dimitrios (Oct 26), its freedom from Turkey and commemorates the entry of the country in World War II.
Also in Thessaloniki, you can take a look at the jewelry exhibited at Kosmina (on Oct 17), the only international trade event dedicated to fashion jewelry and accessories industry in Greece.
