Best Places to Visit in Greece in September
Greece in September is one of the best places to visit in Europe since it’s one of the quieter places. We find this really bizarre as it’s still got exceptional weather, but we won’t let the secret out if you don’t.
Weather in Athens, Greece, in September
Athens is a wonderful place to be in September. It’s full of sunshine as the sun only sets at 7:45 PM, so wear enough sunscreen (and don’t forget to reapply). As Greece’s capital city, there are countless things to do in Athens.
As the birthplace of democracy and many a philosopher, Athens is full of history. A marvelous way to explore this is by taking this Best of Athens tour. You’ll see the Acropolis, the Parthenon, and other famous sites that you probably learned about in school.
Besides Athens’ historical attractions, the city also has stunning beaches to laze on and warm waters to dip the toes into. Some of the best beaches near Athens include Brexiza and Sounio Beach.
If you want to visit Sounio, consider booking this Temple of Poseidon sunset excursion for an exciting tour of Greek mythology.
Crete Weather in September
The weather in Crete in September is absolutely splendid, with an average temperature of 80ºF. We think it might even be one of the best Greek islands to visit in September, with over ten sunshine hours and lovely Cretan hospitality.
There are many places to stay in Crete, as it’s easier to find more affordable accommodation in Greece’s fall season. Another great reason to visit Crete is there’s so much to do, such as this Heraklion for foodies culinary tour, perfect for food connoisseurs.
Imagine yourself feasting on mouth-watering treats, such as loukoumades or the freshest seafood. Yep, that’s why we love Greece!
Santorini Weather in September
The weather in Santorini, Greece, in September is one of the reasons why this is such a tremendous month to visit this Greek island. It’s much more moderate than Crete and Athens, regardless of what the other locals try to tell you.
In fact, this might be the best time to visit Santorini, especially if you want a more chilled stay. It’s much more secluded than in the summer, as it’s off-season for the island. The average low temperature is only 50ºF, hardly like autumn anywhere else in Europe.
For a truly memorable experience in Santorini, take this sunset wine experience to taste some delicious Raki. This is perfect after spending a day on the beach, which you’ll want to do, as the water temperature is (surprisingly) hotter than in summer.
Weather in Mykonos, Greece, in September
When you think of Greece, Mykonos likely comes up as one of the spots to visit. Mykonos’ nightlife is internationally famous, with hundreds of thousands flocking to the island yearly during summer.
This hustle-and-bustle usually lasts until August, with Mykonos’ weather in September cooling down slightly as fall begins.
We love Mykonos during this time, as the prices go down, but the weather remains hot, with the average sea temperature warm and steady. The weather in Mykonos in September shows off stunning days, with cooler temperatures coming in the evenings.
However, you must remember that the average wind speed in the Cyclades is always high, especially compared to northern and eastern mainland Greece, and pack your suitcase accordingly.
There are still so many things to do in Mykonos besides the nightlife. This private half-day Mykonos highlights tour is one of the finest ways to explore the island. It’s superb as you’ll get to see some of Mykonos’ beaches and maybe even take a dip in the Aegean Sea!
Weather in Corfu in September
Corfu, the Island of the Phaeacians, is a brilliant place to be in the fall. Corfu’s weather in September is perfect if you want a tan. The average high temperature is 82ºF but don’t get caught outside without your rain jacket, as Corfu does get more average rainfall than the rest of Greece.
That being said, the weather and sea temperatures during September will allow you to get an authentic feel of what the island is like and offer you the opportunity to experience the best it has to offer.
Due to its location as Greece’s northwestern point, it is an important location in history. In fact, the Venetian influence on the island led to a period of Enlightenment that the rest of Greece never experienced.
Experience the incredible architecture and its unique food culture first-hand in this Corfu Old Town tour.
Final Thoughts on Greece's Weather in September
The weather in Greece in September is hot and sunny skies can be found in all Aegean and Ionian islands, with the temperatures boasting an average high of a balmy 82 degrees Fahrenheit and an average snowfall of zero. Despite the sun shining down relentlessly, showers are never too far away.
In fact, Greek gods have been known to emulate Zeus with dramatic thunderstorms of their own. So don't forget your raincoat - it's always better to be prepared than caught off guard by an unexpected shower!
