Vitality score

Vitality score 34.4/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 44 % of the 13,945 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 FONTENAY weather station, 8.6 km away at 20 m; the village itself is at 89 m. ^[11]

The village sits 69 m above the station, so each day's reading was shifted by 5.71 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[11]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[11]

Humidity measured at FONTENAY, 8.6 km away at 20 m, over 21 summers. ^[11]

That station sits 69 m below the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[11]

An average of 874 mm of rain a year, spread over 122 days — about 7.2 mm on a day it rains. ^[11]

Rainfall measured at FONTENAY LE COM, 6.5 km away at 35 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
