Santorini, Greece

September travel to Greece provides visitors with the best of all worlds—lighter crowds, lower prices, pleasant weather and a full slate of events and attractions. In September, you can enjoy music festivals, picturesque religious feast day celebrations, and the Athens International Film festival.

Most tourists will find attractions open toward the last part of the month less crowded. Transportation schedules start to cut back about September 15.

A few places on the Greek islands will close at the end of the month, and activities for children start to wane as the school year begins.

September is also the beginning of the repositioning cruise Season. This is when many cruise lines offer some great discounts while getting their European vessels over to the Caribbean for the winter season.

Greece Weather in September

The climate in Greece is typical of the Mediterranean countries with mild and rainy winters, warm and dry summers and, lots of sunshine. There are regional variations. The winter is milder in the Aegean and Ionian Islands as compared with the northern and eastern mainland of Greece. The Greek islands may be more humid than mainland Greece.

The beginning of September in Athens is still warm but the heat of the summer dissipates by the end of the month as fall approaches.

The average temperature in the Athens area is 75 F and 24 C (average highs can reach 82 F), with the average low dropping to 66 F (19 C).

Expect sun at the beginning of September. The end of September also offers sunny skies, with just a little more chance of rain. It's swimming weather at the beach because the water is fairly warm.

 The average sea temperature in September is 75 F (24 C). 

In the Greek islands, temperatures are just a little warmer. During September on Santorini, the average temperature is 77 F (25 C) on September 1st and gradually decreases until it reaches 72 F (22 C) by the end of the month. And it's gloriously sunny in the Greek islands too.

Greece enjoys an average of 11 hours of sunshine every day during September making outdoor activities ideal. 

What to Pack

You'll need good walking shoes for exploring ruins and walking along cobblestone streets. And, for the beach, sandals are perfect. If you'll be in the water, consider a pair of water-walking sandals in case you step on a sea urchin or sharp rock. 

A bathing suit is a must as are sundresses and short-sleeved shirts. Don't pack too many t-shirts because you'll find plenty of souvenir t-shirts in Greece. For evening, or in case of a rare rain, bring a lightweight jacket. Toward the end of September when the weather is cooler, layering will keep you comfortable. In beach areas, you can enjoy dressing lightly with flowing cotton fabrics. If you are visiting churches or religious festivals, long pants or skirt and a sleeved shirt will be appropriate.

 

September Events in Greece

September in Greece brings opportunities to attend large events and small-village religious feast days. Music festivals abound. Major festivals include:

  • Hellenic Festival, also called the Greek Festival, including the Athens Festival and the Epidaurus Festival of Ancient Drama and Music, usually continues through mid-September. The Hellenic Festival uses the open-air theatre of Lykabettus, a landmark in the center of Athens, for concerts during the summer months and September.
  • Armata Festival takes place at the beginning of September in Spetses. The festival marks the battle in the strait between Spetses and Kosta during the revolution of 1821. The festival events include adult and children's theatre, local Greek dance, music, and shows. The grand finale, usually held around September 8, begins with a parade of lighted boats circling a specially constructed "Turkish ship," that will be destroyed in the ensuing battle re-enactment.

September Travel Tips

September is a time when crowds thin out at children return to school. You'll have more of a chance to take in the sights in detail. Here are some tips to ensure you have a great time. 

  • Touring Greece requires sensible shoes. In fact, the Greek government banned the wearing of spike heels at historic sites as they can cause damage to the ancient areas.
  • You can avoid crowds by visiting toward the end of the month. But you need to check ahead because some attractions close when the children return to school.
  • Check the ferry schedules if you are going to the Greek islands. September and October is the time when ferries change their schedules and eliminate some connections.
