Weather in Warsaw in March

A hard month. March asks something of you. Go in knowing what. Highs sit at 7.3 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

March ranks 8 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, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 7.3 °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: 20 nights drop below freezing, so anything left outside stays frozen. Across the twenty years measured, the hottest March day reached 21.1 °C and the coldest night fell to -18.2 °C.

March is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest March on record still delivered 69 mm against 17 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 39 mm average is a reasonable planning figure, not a promise.

Wind is light at 12 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, which at 7.3 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How March sits in the year

The month is on the way up: 5.8 °C warmer than February, and April adds another 7.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

11.8 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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

March 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 March — 2.4 °C cooler, 1 day more rain.

So: March is a compromise. September is 41 points better and is what Warsaw is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
