The average amount of daily sunshine in September is seven hours, which still gives visitors plenty of time to enjoy the sun. Even though there is slightly less sunshine this month, September sees very little rain.


The average rainfall in September is just 10mm, spread out over the course of three days, meaning you won't lose one of your vacation days to the weather.

Sea Temperature 

Although the temperature drops slightly this month, going to the beach is still a popular activity this month because of the warm water to swim in. The average sea temperature in September is 24°C (75°F), which is considered warm to everyone, regardless of how long you stay in.


Athens is not a humid city during the majority of the year, but the humidity levels do rise significantly from August to September. The average humidity in September is 60%, which is up from 50% in August. This is still a comfortable level and the humidity should go unrecognized.

Athens Hotels in September 

Opened in 2005, the Centrotel Hotel is a seven-floor hotel with 53 rooms and 6 suites for guests to choose from. The rooms consist of single, double, and triple options, while the suites can sleep up to four people. Every room comes with air-conditioning, a balcony, wireless Internet, and room service.

Amalia Hotel is a four-star hotel that was fully renovated in 2007 and offers 97 rooms and one suite. Every room comes with "double glazed" windows, which neutralize outside noise while still allowing plenty of natural light, as well as air-conditioning. The hotel has a lounge in the lobby, which offers drinks and light snacks, while overlooking the National Gardens. There is also a restaurant offering buffet-style breakfast, in addition to lunch and dinner served a la carte. The Amalia Hotel is located just a three minute walk from the city centre and is walking distance to several of historical sites.

Athens Beach for September 

Voula Beach is separated from the main road by pine trees, making it feel more secluded than nearby beaches that do not have a tree line. The sandy beach has a few coves that are useful for swimming, as the water here is calm and still. There are several areas to rent umbrellas and sunbeds, and there is also a sports centre (with tennis and volleyball courts) on the beach offering lessons. Lining the beachfront are numerous cafes, bars, and taverns, offering food/drink with a view of the sea. If you prefer to leave the beach for your meal, Il Salotto is about a 15 minute walk into the city and offers authentic Italian food. Voula Beach is about a 20 minute drive from the city centre and can be accessed by Athens' public transportation.

Marathon Beach is famous for being the site of the Battle of Marathon (fought between the Greeks and the Persians) in which a messenger ran 42 km from here to Athens to deliver a victory announcement for the Greeks. This story created what we know today as "marathon" races, which consist of the same distance the messenger ran. The beach itself is popular for windsurfing as the wind can be quite strong here, and there are trees and plants scattered throughout the sandy beach. There are sunbeds and umbrellas for rent and a paved walkway just off of the beach that can be used for jogging or cycling. About two blocks off of the beach is Enas k Enas, a restaurant serving traditional, homemade Greek dishes and seafood. Marathon Beach is about a 42 minute drive from the city centre.

Bars and Restaurants 

If you are in the mood for Greek food, but something that is a little different, try Mani Mani. They offer traditional Greek dishes, but are created using a modern twist. You can find orzo, traditional Greek pastas, grilled meats and fishes, as well as a selection of starters, salads, and desserts on their menu. They are open from 2:30 PM to 11:30 PM on Monday to Friday, from 1 PM to 11:30 PM on Saturdays, and from 1 PM to 5:30 PM on Sundays. Mani Mani is about a 17 minute walk from the city centre.

Fresko Yogurt Bar was created because a place that served traditional Greek yogurt mixed with sweets did not exist in Athens. All of their products are created using high quality, local ingredients, which are always fresh and not frozen, to ensure an authentic taste. They offer five different types of yogurt and ten different "spoon sweets," like black cheery or blueberry, which can be added to the yogurt. The yogurt bar is located about an 11 minute walk from the city centre.

Things to do in Athens in September 

The Dora Stratou Dance Theatre was created in 1953 and is considered to be a "living museum." They perform several shows throughout the week and the theatre seats 800 people. The performers consist of 75 "dancers, musicians, and folk singers," and their costumes (over 2,000 of them) are exquisitely handmade and authentic, as they were purchased from local village people who created them. The performances begin at 9:30 PM on Wednesday through Friday, at 8:15 PM on Saturdays and Sundays, and they are closed on Mondays and Tuesdays. The theatre is an eight minute walk from the city centre.

If you are looking for some excitement, head to Allou Fun Park. They are an amusement park offering various thrilling rides, in addition to carnival-style games. Their rides include things like the "4G," which turns you upside down and takes you 40 metres into the air, while traveling at a high speed, or the "Shock Tower," which slowly rises you up before shot back towards the ground at speeds 2.5 times faster than free falling. They also have rides that are tamer, such as a Ferris wheel and bumper cars. The park has several options for food/drink and they are open Monday through Friday from 5 PM to 11 PM, and Saturday/Sunday from 10 AM to 11 PM. The park is about an 11 minute drive from the city centre.

The Kerameikos Ancient Cemetry of Athens Archaeology Site and Museum is a must visit for history lovers. There are ruins and graves in the ground, it's a great place to walk around. September is an ideal month to visit as it isn't overly crowded and the weather is still warm and cheerful.
