Inside and outside

10 °C inside, all year.

Deep inside, a cave keeps the average temperature of the year outside: about 10 °C here, in January and in August. In July the afternoon reaches 26 °C at the entrance, 16 °C warmer than inside: take a jacket. The wettest months are in July: water rises fast underground, so never go in without a guide after heavy rain.

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.
