Vitality score

Vitality score 39.6/100 — Few services (model fr-v0.2).

Confidence: medium (sources disagree on Restaurant).

Better served than 58 % of the 13,797 communes of a similar size.

Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.

Muggy days — a dew point at or above 18 °C — average 0 days a summer. ^[12]

Humidity measured at GRENOBLE-ST GEOIRS, 13.1 km away at 376 m, over 30 summers. ^[12]

That station sits 122 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[12]

An average of 1,054 mm of rain a year, spread over 112 days — about 9.4 mm on a day it rains. ^[12]
