Vitality score

Vitality score 47.7/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 98 % of the 17,034 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 9 days a year at or above 30 °C and 104 days at or below 0 °C, over 22 complete years in 1995–2024. ^[12]

Measured at the CESSY weather station, 10.8 km away at 507 m; the village itself is at 887 m. ^[12]

The village sits 380 m above 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 0 days a summer. ^[12]

Humidity measured at CESSY, 10.8 km away at 507 m, over 23 summers. ^[12]

That station sits 380 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 1,402 mm of rain a year, spread over 130 days — about 10.8 mm on a day it rains. ^[12]

Rainfall measured at GEX, 10.3 km away at 618 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
