Lisbon in January The holiday mood lingers in the first week. Rain comes and goes, but clear days can be warm enough to go without a heavy coat. Few tourists mean shorter queues at Belém Tower and the Jerónimos Monastery.
January in Lisbon was brisk: 15°C by day, 9°C at night. Standing in the shade felt chilly. There were 10 rain days on average, roughly one day in three. A visitor in 2022 met 2 rain days; one in 2014 met 19. The average of 10 hid that gap.
Days were short. Daylight grew from 9.5 to 10.2 hours across the month, so plan outdoor sights early. Cold snaps happened: the record low for January was 1.7°C, set in 2009.
