Weather in Gdańsk in April

A hard month. April is a hard month in Gdańsk, and worth planning around. Highs sit at 9.8 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

April ranks 7 of 12 in Gdańsk: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 8 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 9.8 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 22.3 °C and the coldest night fell to -1.6 °C.

April is moderately variable: 3 mm in the driest year against 72 mm in the wettest, around an average of 36 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 13.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, which at 9.8 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How April sits in the year

The month is on the way up: 4.9 °C warmer than March, and May adds another 5 °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

14 hours of daylight, gaining 2.1 hours across the month. That is between Gdańsk's extremes of 17.2 and 7.4 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 4.3 °C in April — too cold to swim without a wetsuit. The sea peaks at 18.8 °C in August and bottoms out at 3 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

April in Gdańsk versus nearby

If Gdańsk is one option among several, the nearby comparison is worth making. Warsaw is a better bet in April — 4.6 °C warmer, 1 day more rain. Szczecin is a better bet in April — 2.9 °C warmer, the same number of rain days.

So: April is a compromise. August is 28 points better and is what Gdańsk is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
