Vitality score

Vitality score 31.2/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 31 % of the 13,695 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.

Measured but not scored in this model: Market. See the methodology for why.

Climate

An average of 28 days a year at or above 30 °C and 64 days at or below 0 °C, over 25 complete years in 1995–2024. ^[12]

Measured at the AUTRANS weather station, 9.8 km away at 1,069 m; the village itself is at 219 m. ^[12]

The village sits 850 m below the station, so each day's reading was shifted by 6.06 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[12]

Muggy days — a dew point at or above 18 °C — average 4 days a summer. ^[12]

Humidity measured at COUBLEVIE, 15.3 km away at 300 m, over 19 summers. ^[12]

That station sits 81 m above 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 1,042 mm of rain a year, spread over 106 days — about 9.8 mm on a day it rains. ^[12]

Rainfall measured at TULLINS, 6.1 km away at 190 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
