Vitality score

Vitality score 37.5/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 34 % of the 10,383 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 at the THONON-INRAE weather station, 6 km away at 376 m; the village itself is at 665 m. ^[12]

The village sits 289 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 1 day a summer. ^[12]

Humidity measured at THONON-INRAE, 6 km away at 376 m, over 30 summers. ^[12]

That station sits 289 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 992 mm of rain a year, spread over 117 days — about 8.5 mm on a day it rains. ^[12]

Rainfall measured at THONON-INRAE, 6 km away at 376 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
