Greece in September is a beautiful transition period from the peak summer months into early autumn. While the sun still shines brightly and the sea stays warm, the crowds begin to thin out-offering a more relaxed yet still vibrant atmosphere. It’s one of the best times to visit for pleasant weather, lower crowd levels, and unique seasonal experiences.
Weather in Greece in September
September in Greece remains warm and sunny, with temperatures ranging from 18°C to 30°C (64°F to 86°F). The southern islands like Crete and Rhodes tend to be hotter, while the northern mainland is slightly cooler, especially in the evenings.
Humidity levels are moderate, and sunshine averages 9 to 10 hours per day, making it ideal for beach outings and sightseeing. Evenings can feel cooler, especially in the inland or northern parts of the country, so it’s a good idea to pack a light jacket or sweater.
Tip: Pack summer clothes for the day and a few layers for evenings, especially if you're heading north or visiting mountainous areas.
Rainfall in Greece in September
September is one of the drier months in Greece. Rainfall is limited and varies slightly depending on the region, with an average of 15–30 mm of rain during the month, mostly in short, infrequent showers. The Cyclades and southern islands stay especially dry.
The sea temperature remains inviting, averaging between 23°C to 25°C (73°F to 77°F), making it perfect for swimming, snorkeling, and other water activities.
Crowds and Prices in Greece in September
Although the temperatures are similar to July and August, September marks the start of the shoulder season. This means fewer crowds, shorter queues at major attractions, and a more laid-back pace—especially toward the end of the month.
Most restaurants, beach clubs, and nightlife spots are still fully operational. However, prices for flights and accommodation may only slightly dip, especially in the early part of the month. You can expect more budget-friendly rates in smaller towns and during the final week of September.
