How The Month Feels
January feels brisk and damp, with frosty nights and a lot of rainy days but very little sunshine. The practical rhythm is indoors first, with outdoor sightseeing added only when conditions are acceptable.
What To Lock In Early
With prices and crowds low, you can usually keep plans flexible and adjust day by day. Still, if you want specific museum time slots as your core activity, reserve ahead so bad weather doesn’t force last-minute changes.

Quick answers
Sometimes, but it is more of a selective pick than an all-purpose recommendation.
Expect around 1.5°C by day and -3°C at night, with 64.2 mm of rain across roughly 15.4 rainy days.
Pack warm layers, a light rain jacket, and shoes that handle wet pavements well.
Often yes. This kind of month can make more sense on value than on perfect conditions, especially if cheaper stays and flights matter more than peak-season polish.
