Weather in Liberec in January

The month to avoid. Of the twelve, January is the one to avoid. Highs sit at 0.2 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 12 of 12 — near the bottom of Liberec's year. September is the month that works, and the swing between the two is 61 points, which is a different holiday rather than a slightly better one.

This is persistent light rain rather than storms: 15 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Layers, and a genuinely waterproof outer — at 0.2 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 26 nights drop below freezing, so anything left outside stays frozen; the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 11.4 °C and the coldest night fell to -27.5 °C.

January is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest January on record still delivered 114 mm against 27 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 64 mm average is a reasonable planning figure, not a promise.

Wind is light at 12.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 94%, which at 0.2 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How January sits in the year

This is a turning point in the year — December and February sit on opposite sides of it, so the month contains the change rather than following it.

Daylight in January

January sits at the dark end of Liberec's year — 8.4 hours of daylight against 16.5 at midsummer, gaining 1.1 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

With no coast nearby, the year swings a fair way — 29.2 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Liberec versus nearby

If Liberec is one option among several, the nearby comparison is worth making. Prague is close enough to be a coin toss — 2 °C warmer, 3 days less rain. Wrocław is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: January is a compromise. September is 61 points better and is what Liberec is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
