Weather in Wrocław in May

A good month. May works. It is not the peak, but nothing about it fights you. Highs average 19.6 °C, lows 9.1 °C, and rain falls on 13 days — nothing in the month is working against you.

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

Rain on 13 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 31.7 °C and the coldest night fell to -1.3 °C, and the wettest single day dropped 25 mm — roughly 36% 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 140 mm against 33 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 69 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 is unremarkable at 72%.

How May sits in the year

The month is on the way up: 4.6 °C warmer than April, and June adds another 4.2 °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 1.5 hours across the month. That is between Wrocław's extremes of 16.5 and 7.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 30.7 °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 Wrocław versus nearby

If Wrocław is one option among several, the nearby comparison is worth making. Liberec is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Prague is close enough to be a coin toss — within a degree on temperature, 1 day more 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.
