Vitality score

Vitality score 27.7/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 51 % of the 17,720 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

An average of 23 days a year at or above 30 °C and 42 days at or below 0 °C, over 30 complete years in 1995–2024. ^[11]

Measured at the ST-LEON weather station, 13 km away at 376 m; the village itself is at 280 m. ^[11]

The village sits 96 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. ^[11]

Muggy days — a dew point at or above 18 °C — average 3 days a summer. ^[11]

Humidity measured at FERTE-HAUTERIVE, 14.9 km away at 226 m, over 17 summers. ^[11]

That station sits 54 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[11]

An average of 807 mm of rain a year, spread over 122 days — about 6.6 mm on a day it rains. ^[11]

Rainfall measured at JALIGNY, 5.1 km away at 285 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]

What property sold for

36 houses sold between 2021 and 2025, at a median of 84,705 € — 878 € per m² of built surface. ^[12]

The median across Allier is 924 € per m², so this commune sits about level with it. ^[12]

These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
