Inside and outside

19 °C inside, all year.

Deep inside, a cave keeps the average temperature of the year outside: about 19 °C here, in January and in August. In July the afternoon reaches 33 °C at the entrance, 14 °C warmer than inside: take a jacket. The best months to escape the heat are from May to September. The wettest months are from May to September: water rises fast underground, so never go in without a guide after heavy rain.
