Is December 2026 a good month to visit Santorini?
Calm — the typical December day in Santorini is calmer than 85% of its year.
The weather is the trade-off here, not the crowds.
Calm · Lively · Busy · Packed rank a day against Santorini's own year — not a headcount.
December 2026 is the Santorini most visitors never see — Calm every day, mild and showery, around 16°C / 61°F with rain on about 9 days.
Yes. December in Santorini is Calm on the typical day, and not one of the 31 days in our window is crowded enough to call Busy. Expect around 16 °C by day, with rain on about 9 days. The crowd comes with the school holidays in Germany, the Netherlands and France. Early December is the month's quietest stretch in Santorini — the typical day at 15%, against 34% in late December. The crush is at Oia at sunset; the quiet is at the caldera path between the towns. The calmest day is Tuesday 1 December, the busiest Friday 25 December.
In short, a genuinely good window to pick.
Among the 12 months we forecast for Santorini, December ranks 8th for crowd pressure. Its heaviest day is Fri 25 Dec, busier than 36% of the year; its lightest is Tue 1 Dec at 15%.
You won't need skip-the-line tickets here — that's rather the point. A month like this is the one for the longer visit — the guided walk, the food tour, the day out of town, with room and time to enjoy them. see what's on →
Nothing extreme to plan around — rain on 9 of 31 days.

Which week of December is quietest in Santorini?
Early December is the month's quietest stretch in Santorini — the typical day at 15%, against 34% in late December.
The upside of a quiet December
- Walk straight into the sights that sell out in high season — no timed ticket, no queue.
- Keep the days loose — decide over breakfast, not weeks ahead.
- Early on, you can have the busiest spots almost to yourself — bring a camera.
No queues to skip, and nothing to book ahead — that's the whole point.
December weather in Santorini
Mild — around 16°C / 61°F, with a light jacket for the evenings, with rain on about 9 days, so keep a layer handy. Daylight is short, about 10 hours, so plan the big sights for the middle of the day.
This is the value month: no need to book far ahead, and the freedom to change plans on the day is part of what you're getting.
