Pressure and weather in Gdansk
Gdansk lies on the southern shore of the Baltic Sea, where the Vistula delta opens into the Gulf of Gdansk and the flat Zulawy plain rolls out to the south. Weather here is a tug of war between maritime air from the west and continental air from the east. Atlantic depressions cross Denmark and the southern Baltic mostly from October through February, bringing strong westerly and northwesterly winds, fast pressure falls and, occasionally, storm surges that push seawater into the river mouth. When a Russian or Scandinavian high builds instead, the city turns clear, dry and cold, with pressure climbing steadily for days. The sea also moderates the summer, keeping heat waves milder than inland Poland, though sea breezes and passing troughs can trigger short afternoon storms in July and August. The stormiest and least stable stretch is late autumn into midwinter.
What this means for you
In Gdansk the biggest pressure movement clusters from October to February, when Atlantic lows sweep across the southern Baltic and the barometer can drop sharply within a day. Checking the current barometric pressure each morning and keeping notes in a migraine tracker app can reveal whether a weather migraine tends to follow those gale-driven falls or the steadier rise behind them.
