When the weather turns in Santorini
Rain is genuinely rare and confined to roughly November through February, which is also when the fewest places are open. Akrotiri is entirely roofed and works in any weather. The Museum of Prehistoric Thera is a short indoor visit, and the winery tasting rooms at Santo Wines and Venetsanos are covered. Before driving up in winter, check what is actually trading, because assumptions fail here.
Santorini's museums, and which one to pick
Akrotiri, 20 euro, is a Bronze Age town preserved under volcanic ash beneath a modern roof, with multi-storey walls, drainage and streets intact and, notably, no human remains found. Its frescoes were moved to the Museum of Prehistoric Thera in Fira, where the boxing boys and blue monkeys hang. Ancient Thera, 10 euro, sits on the Mesa Vouno ridge and closes Wednesdays.
What to eat in Santorini
The island's volcanic soil produces small, intense dry-farmed tomatoes that become tomatokeftedes fritters, plus PDO fava, a yellow split-pea puree eaten warm with onion and capers, and a white aubergine unique to the island. Assyrtiko vines are trained into basket-shaped kouloura coils flat to the ground against the wind; Santo Wines and Venetsanos both pour with a caldera view. Ammoudi Bay grills octopus at the waterline.
What first-timers get wrong in Santorini
Every KTEL bus routes through Fira, so there is no direct Oia to Perissa service and you will change. From 2026 a cruise passenger cap of 8,000 a day plus a 20 euro levy limits how many ships call. Quad and ATV rentals require a proper licence and account for a disproportionate share of island accidents. Oia dinner reservations need booking days out.
What things cost in Santorini
Most KTEL routes cost 2.20 euro, including Fira to Oia; Fira to Athinios port is 2.70 and Vlychada 2.80. Akrotiri is 20 euro and Ancient Thera 10. Caldera catamaran cruises start near 69 euro and rise with food and open bar. The August price of a caldera-view room is a multiple of the May price for the identical room.
When to go to Santorini
| Best months for rainy day | Avg daily high | Rain days |
|---|---|---|
| June | 28°C / 82°F | 1 days |
| September | 28°C / 82°F | 1 days |
| October | 24°C / 75°F | 2 days |
The month to avoid is January — around 15°C (59°F) with roughly 8 rain days. Prices and crowds track the weather here: June is the sweet spot, January the month most people skip.
Pack for peak season: Summer clothes, plus one light layer for air-con and evenings, High-SPF sunscreen, sunglasses, and a refillable water bottle, Comfortable walking shoes — every guide on this site assumes you'll use them.
Where to base yourself in Santorini
- Oia — Sunset spot, blue-domed churches, luxury hotels.
- Fira — Capital, nightlife, the cable car to the port.
- Imerovigli — Quieter caldera-view base, fewer crowds than Oia.
- Akrotiri — Lighthouse, prehistoric ruins, the more affordable south.
