Weather in Liberec in May

A good month. May is a solid month to be in Liberec. Highs average 17.8 °C, lows 7.6 °C, and rain falls on 14 days — nothing in the month is working against you.

May ranks 5 of 12 in Liberec: past the worst of the year but short of September, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 14 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 17.8 °C days and 7.6 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest May day reached 28.1 °C and the coldest night fell to -1.4 °C, and the wettest single day dropped 28 mm — roughly 41% of the month's rain in one day.

May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 132 mm against 36 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 68 mm average is a reasonable planning figure, not a promise.

Wind is light at 9.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way up: 4.4 °C warmer than April, and June adds another 3.7 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain has already shifted: 5 days more than April had.

Daylight in May

15.5 hours of daylight, gaining 1.4 hours across the month. That is between Liberec's extremes of 16.5 and 8 hours, so days are long enough not to constrain the plan.

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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

May 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 — 2.2 °C warmer, the same number of rain days. Wrocław is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: May works, with September the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
