Florence weather in December

December in Florence brings crisp winter conditions with daytime temperatures around 11.8°C (53°F) and chilly nights dropping to 3.5°C (38°F). Expect moderate rainfall totaling roughly 104mm spread across 12 rainy days, so wet weather is common. Sunshine is limited to about 5.6 hours daily, creating those moody, atmospheric Florentine afternoons perfect for indoor exploration. The Arno often reflects grey skies, and the city takes on a quieter, more introspective character.

This is peak holiday season in Florence. The city decorates festively, and Christmas markets fill the piazzas with seasonal charm. Crowds thin considerably compared to summer and autumn, giving you breathing room at major attractions like the Duomo and Uffizi Gallery. The atmosphere feels intimate rather than touristy—locals reclaim their city, and you'll experience Florence more authentically. December also means lower accommodation prices and shorter queues.

For 2026 travelers, December is ideal if you prefer fewer tourists and don't mind cooler, wetter weather. Book indoor activities like museums and galleries in advance. Pack layers and waterproof gear. The mild temperatures make walking manageable, and the reduced crowds make this one of the best months to visit Florence if you value experience over sunshine.
