Santorini is a crescent-shaped caldera left behind by one of the largest volcanic eruptions in recorded history. The blue-domed churches and whitewashed houses of Oia and Fira sit on cliffs high above the water. Cruise ships anchor inside the caldera and tender passengers ashore to reach the black-sand beaches, the Bronze Age ruins at Akrotiri, and the island's restaurants.
Santorini in December brings cooler conditions, with highs around 59°F, so pack layers alongside your warm-weather gear. Expect around 10 rainy days, typically brief afternoon showers rather than all-day rain. Morning excursions are usually the safest bet. Cool and quiet
Crowds are moderate in December, making it a good balance between availability and weather. Dress in layers: a waterproof shell over a mid-layer handles the range between cool mornings and afternoon port temps.
