A twelve-month profile of temperature, precipitation, humidity, and wind patterns
Detailed climatological data for the Kacze Łęgi representative coordinate in the Pomeranian Voivodeship, covering the period from 1991 to 2020. This data tracks monthly mean, minimum, and maximum temperatures alongside average daily precipitation, relative humidity, and wind speed. These measurements provide a consistent long-term baseline for understanding the annual atmospheric rhythm within this protected nature reserve.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
