The best time to visit
There is no single wrong season, but the season changes what you get. Spring and autumn are the calmest, with mild weather and smaller crowds than the peak summer months. Summer is the busiest, when the light is strongest and the villages are fullest. Winter is the quietest, though some services slow down. If you want fewer people around you, visit in the shoulder months; if you want the strongest colour in your photos, aim for the hours around sunrise and sunset. Nothing here guarantees a specific view — clear weather helps, and so does checking the forecast before you go.

Frequently asked questions
Where is Santorini?
Santorini is an island in the Cyclades, an island group in the Aegean Sea, part of Greece. It sits inside Thira Municipality, at 36.42°N, 25.43°E. Wikidata records it as both an island and a tourist destination, and the island belongs to a wider Santorini archipelago that shares its name. The municipality's official website is thira.gr.
How high is Santorini?
The island's highest point reaches 567 metres above sea level, the figure Wikidata records as its elevation. The flooded caldera the villages overlook is recorded separately in Wikidata and dated to around 1613 BC. That caldera is what gives the island its steep cliffs, so the summit figure and the caldera date describe two different parts of the same place.
How big is Santorini?
The island covers 79.194 square kilometres, a figure Wikidata records for its area. It belongs to the Cyclades, an island group in the Aegean Sea, within Thira Municipality in Greece. The same entry also lists it as part of a wider Santorini archipelago that shares the island's name and spreads across the surrounding waters.
How many people live on Santorini?
Wikidata records 17,430 residents in the 2011 census. That is the most recent census figure recorded for the island in the dataset, so treat it as a snapshot rather than a current count. The island is a tourist destination, which means the number of people present in summer is far larger than the resident figure.
When was the Santorini caldera formed?
Wikidata dates the caldera to around 1613 BC. It is recorded as a separate entry named after the island itself, and it is the flooded crater the villages are built around. The caldera sits at its own set of coordinates in the dataset, distinct from the island figure quoted in the rest of this guide.
What is the best time of year to visit Santorini?
Spring and autumn are the calmest, with mild weather and smaller crowds than summer. Summer is the busiest and winter the quietest. For the strongest photo light, aim for the hours around sunrise and sunset. If your priority is space to move, the shoulder months beat July and August, and clear weather always helps.
What language is spoken on Santorini?
The island is part of Greece, and Greek is its official language. The municipality's official website is thira.gr, where you can check local services before a visit. Since the island is a tourist destination, English is widely used in the villages around the caldera, especially through the busy summer months.
