October in Santorini offers a beautiful blend of lingering warmth and fewer crowds, making it an ideal time to visit. However, the shoulder season weather can be a bit unpredictable, so smart packing is key to enjoying everything this stunning island has to offer, from breathtaking sunsets to charming villages.
We'll tune the list to your exact trip — dates, activities, and weather.
October in Santorini sees average high temperatures around 73°F (23°C) and lows around 64°F (18°C). While rainfall is generally low, averaging about 2 inches (50 mm) for the entire month, occasional showers are possible. Humidity hovers around 70%, and you can expect around 11 hours of daylight, with sunsets still a spectacular event.
Dress for comfortable transitions between warm days and cooler evenings. Light layers are your best friend, allowing you to adapt to temperature changes and the island's famous strong winds. While Santorini is laid-back, avoid overly revealing beachwear outside of designated beach areas, especially when visiting churches or more traditional villages.
