Inside and outside
11 °C inside, all year.
Deep inside, a cave keeps the average temperature of the year outside: about 11 °C here, in January and in August. In August the afternoon reaches 30 °C at the entrance, 19 °C warmer than inside: take a jacket. The best months to escape the heat are from July to August. The wettest months are in May: 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.
