How The Month Feels
Expect long stretches of cold, wet days with very limited sunshine—only about 2.2 hours per day on average. With outdoor options only half of the mix, most sightseeing time will naturally shift indoors.
What To Lock In Early
With low crowds and low prices, you can usually keep plans simple and avoid overplanning. If you’re aiming to spend time at the Obserwatorium Astronomiczne or a specific museum day, reserve only if you’re on a tight schedule.

Quick answers
Sometimes, but it is more of a selective pick than an all-purpose recommendation.
Expect around 1.8°C by day and -2.5°C at night, with 63.7 mm of rain across roughly 15.8 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.
