Weather in Kraków in May

A good month. May is a solid month to be in Kraków. You should expect rain on 16 days of the month, which is more days wet than dry.

May ranks 3 of 12 in Kraków. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.

This is persistent light rain rather than storms: 16 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average May reaches 30 °C. Across the twenty years measured, the hottest May day reached 30.8 °C and the coldest night fell to -1.5 °C, and the wettest single day dropped 50 mm — roughly 51% of the month's rain in one day.

May is moderately variable: 46 mm in the driest year against 273 mm in the wettest, around an average of 99 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 8.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way up: 4.7 °C warmer than April, and June adds another 3.6 °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

15.4 hours of daylight, gaining 1.4 hours across the month. That is between Kraków's extremes of 16.3 and 8.1 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 31.6 °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 Kraków versus nearby

If Kraków is one option among several, the nearby comparison is worth making. Wrocław is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Warsaw is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: May works, with September the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
