Annual climate pattern

A broad January-to-July thermal swing with outdoor rainfall highest in November

Drôme and Ardèche bat-cave network annual temperature and rainfall pattern

The Drôme and Ardèche bat-cave network's 1991–2020 mean temperature climbs from 2.5°C in January to 22.3°C in July, with average minima and maxima showing the outdoor range. At one point near 466 metres, daily precipitation averages 1.29 mm in July and 3.28 mm in November, summarizing outdoor climatology rather than cave microclimates, live weather, or network-wide conditions.
