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 July the afternoon reaches 27 °C at the entrance, 16 °C warmer than inside: take a jacket. The best months to escape the heat are in July. The wettest months are from August to September: water rises fast underground, so never go in without a guide after heavy rain.
