Twelve-month atmospheric data profile based on regional representative-point climatology
Welski Park Krajobrazowy climate records provide a structured view of seasonal atmospheric patterns, measuring average temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours. Data reflects long-term averages for the 1991-2020 period at a representative coordinate, enabling precise comparison of monthly shifts in natural terrain conditions across the calendar year.

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.
