What's the weather like in Gdańsk by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Gdańsk during May–Sep?
Pleasant and quiet — the Old Town reopens after winter, parks bloom by mid-May, and crowd levels are still low. Pack a jacket and rain shell; April is wetter than May.
Shoulder season (Apr, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
