Inside and outside
9 °C inside, all year.
Deep inside, a cave keeps the average temperature of the year outside: about 9 °C here, in January and in August. In July the afternoon reaches 24 °C at the entrance, 15 °C warmer than inside: take a jacket. The wettest months are in May and from July to August: water rises fast underground, so never go in without a guide after heavy rain.

Recent years
Wet years, dry years.
Rain of each month as a share of the 1991–2020 average. A dry year means a lower river and hotter rock; a wet one, more water in the gorge.
