The influence of weather on outdoor recreation is clear. However, the development of the climate brings an increased frequency of extreme manifestations of meteorological elements. Their negative effects also affect the possibilities of recreation not only in the open countryside, but also in caves. The evidence is the closure of the Punkva caves in the Moravian Karst, due to high rainfall totals. The occurrence of extreme precipitation in summer and early autumn had catastrophic consequences on our territory. The sailing of the electric boat in the Punkva caves was affected, it was completely closed after the floods, and then limited in October. Closed again in January and February due to damage to the electrical installation. There was a significant rise in the level of the Punkva River, layers of mud were deposited in the cave environment, and the electrical installation was damaged. The cause was exceptionally high rainfall totals between September 14 and 16, when daily rainfall totals exceeded 60 mm. However, as far as the Moravian Karst area is concerned, part of the caves were already affected by floods in July. From the point of view of the provision of recreation, it appears that the extremes of the weather will affect it more and more. It will be necessary to create specific forecasts of the occurrence of weather extremes in this area as well.
