Fira, Santorini in October.

October is a fantastic time to visit Santorini, especially for travelers looking for pleasant (not hot) weather, fewer crowds, and lower prices. As the autumn shoulder season progresses, the island transitions from its summer peak to a more tranquil and relaxed state, offering a more authentic experience. October is one of my favorite times to visit.

Overview:
• Weather: The weather in October is generally mild and pleasant, but it is a transitional month, so some variability is possible, particularly towards the end of the month. Pack for a wide range of temps.
• Temperature: Expect comfortable daytime temperatures averaging in the low 20s Celsius (around 70-73°F). The sun is still warm enough for sunbathing, but the intense heat of summer is gone. Evenings become noticeably cooler, requiring a sweater or light jacket.
• Sunshine and Rain: You will still enjoy plenty of sunny days. However, the chance of cloudy days or rain showers increases as the month progresses. The first half of October is sunnier and more stable than the second half.
• Swimming Conditions: The sea retains much of its summer warmth, often being warmer than the air temperature. Average sea temperatures are around 22°C (72°F), which is very pleasant for swimming, especially in the first half of the month.
• Activities: Most tourist services are still available in October, but things begin to slow down as the month wears on.

Boat tour in October in Santorini.

Early October is still a great time for a Santorini boat tour. Later in the month swimming becomes a little less likely as the sea temperature cools.

Boat Tours: Most boat and catamaran tours continue to run daily, though perhaps on a slightly reduced schedule compared to summer. The weather is usually great for sailing, but be aware that an overcast or windy day can make it feel cool on the water.
Winery Tours: Wineries are still open and offer a fantastic experience. Enjoying a wine tasting on a terrace on a warm autumn afternoon is a major highlight.
Nightlife: The nightlife scene winds down significantly throughout October. In the first half of the month, beach clubs are still open, offering a more relaxed and quiet atmosphere. By the end of October, the beach clubs are starting to close. Bars in Fira are still lively throughout October and will remain open well into November.
Beaches: On a sunny day in early October, a comfortable swim is still the norm, as the sea is still inviting. However, beach clubs start to close about mid-October and by the end of the month, the beaches are pretty quiet. (Most restaurants at the beaches remain open the entire month.)
Fira-Oia Hike: The pleasant weather of October makes it an ideal time for a peaceful hike with very few other people on the trail. The views are just as magnificent, and the experience is much more serene. Wind and rain become a possibility as the month progresses so do have clothing for fall weather.

Early October is still swimming weather. (Photo is October 2nd at the Athina Luxury Suites, one of my favorite hotels in Fira.) But by the end of the month the weather is likely too chilly for most visitors to swim.

• Services: Most restaurants, shops, and attractions remain open, especially in the main towns of Fira and Oia. In the beach towns like Kamari and Perissa, some businesses may begin to close down for the winter towards the end of the month. Direct international flights also become less frequent, with most travelers now needing to connect through Athens.
• Crowds: The island is quiet. The large crowds of summer are gone, allowing for a peaceful and relaxed experience. You can explore the iconic villages without feeling rushed, find a front-row seat for the sunset, and enjoy the famous views in relative solitude.
• Prices: This is one of the most affordable months to visit. You can find excellent deals on flights and accommodation, including luxury hotels with caldera views that are a fraction of their summer price. It’s a great opportunity to experience high-end Santorini on a more modest budget.
For Couples: October is exceptionally romantic. The tranquil atmosphere, beautiful sunsets, and lack of crowds create an intimate setting. It’s the perfect time for long dinners, leisurely exploring, and simply soaking in the magnificent views without distraction.
For Families: October can be a great time for families seeking a quiet, budget-friendly holiday, with a few caveats. The weather is comfortable for sightseeing with children, without the worry of intense summer heat. However, families looking for a guaranteed hot-weather beach holiday with a bustling atmosphere may prefer the summer months of June, July, August, or September.
