Vitality score

Vitality score 44.6/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 79 % of the 15,295 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.

Climate

Measured at the MAGNANVILLE weather station, 3 km away at 123 m; the village itself is at 43 m. ^[11]

The village sits 80 m below 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 1 day a summer. ^[11]

Humidity measured at MAGNANVILLE, 3 km away at 123 m, over 30 summers. ^[11]

That station sits 80 m above 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 647 mm of rain a year, spread over 116 days — about 5.6 mm on a day it rains. ^[11]

Rainfall measured at MAGNANVILLE, 3 km away at 123 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
