What the National Park Service says about the weather
Although inside the caves its always 43-48 F, temperatures on the cave trail can range from the 30s up to above 100 degrees F, depending on time of year. Carrying drinking water is a necessity, especially in summer. In the mountains, weather sometimes presents interesting challenges. The cave and cave trail do not close due to rain, unless that rain is heavy enough to bring rockfall. They will close due to high winds/rockfall, or in lightning storms. Call the visitor center if you have specific concerns.
