Weather in Warsaw in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs sit at 14.4 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

April ranks 6 of 12 in Warsaw: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 9 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 14.4 °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: 6 nights fall below freezing. Across the twenty years measured, the hottest April day reached 28.9 °C and the coldest night fell to -5.6 °C, and the wettest single day dropped 25 mm — roughly 61% of the month's rain in one day.

April is moderately variable: 6 mm in the driest year against 89 mm in the wettest, around an average of 41 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How April sits in the year

The month is on the way up: 7.1 °C warmer than March, and May adds another 5.2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in April

13.8 hours of daylight, gaining 2 hours across the month. That is between Warsaw's extremes of 16.7 and 7.8 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 32.5 °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.

April in Warsaw versus nearby

If Warsaw is one option among several, the nearby comparison is worth making. Kraków is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Gdańsk is the weaker option in April — 4.6 °C cooler, 1 day less rain.

So: April works, with September the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
