Off-season — lowest travel prices with still acceptable climate.
January in Santorini is on the cool side — with highs around 15°C (59°F) it's less suited for a beach holiday, but good for sightseeing away from the high season.
Daytime temperatures reach up to 15°C (59°F), cooling to 10°C (50°F) at night (daily average: 13°C (55°F)). With 5 sunshine hours per day and 5 rain days (45 mm (1.8 in)), this is one of the cloudier months. At 17°C (63°F), the water is still quite cool in January — a wetsuit may be useful.
Pack warm clothing and sturdy footwear. Cool temperatures make hiking and cultural trips enjoyable — beaches are off the agenda.
Santorini almost deserted: Oia is a film set without a crew, the white churches shine under a blue sky with no selfie stick in the foreground. Many hotels close in winter — find one that's open and you get the real experience.
