Detailed seasonal rhythm of temperature ranges, rainfall, and daylight for this protected landscape.
Naturpark Nassau climate data provides an analytical view of atmospheric conditions measured over the thirty-year period from 1991 to 2020. This profile presents monthly averages including mean, minimum, and maximum temperatures alongside precipitation rates, humidity, wind patterns, and daylight hours. These values represent climatology at a single primary coordinate within the park to provide a consistent baseline for long-term pattern observation.
