The Risnjak National Park is influenced by Adriatic climate characteristics and the continental climate which interferes with each other within this area and determines its climate specificity. Pleasantly mild hot summers with an average temperature of 20°C are rotated with rainy autumns and springs and long, snowy and cold winters. In the higher areas the average temperatures decrease noticeably and the quantity of precipitations increase which is connected to the quantity of air humidity, the intensity of cloud cover, fog and other such phenomena. Cloud cover reaches a maximum level in November and December, and a minimum in July.
The whole area is characteristic for its typical limestone formed valleys and karst sinkholes and its special microclimate. They represent a separate living area with their own plant communities and typical temperature inversion which makes their environment completely different from that of their surroundings.
