Better served than 21 % of the 11,868 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 LALOUVESC weather station, 5.5 km away at 1,090 m; the village itself is at 749 m. ^[10]

The village sits 341 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. ^[10]

Muggy days — a dew point at or above 18 °C — average 0 days a summer. ^[10]

Humidity measured at PREAUX SA, 8.6 km away at 525 m, over 26 summers. ^[10]

That station sits 224 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[10]

An average of 959 mm of rain a year, spread over 111 days — about 8.6 mm on a day it rains. ^[10]

Rainfall measured at VOCANCE, 4.2 km away at 529 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

What property sold for

15 houses sold between 2021 and 2025, at a median of 88,000 € — 1,321 € per m² of built surface. ^[11]

The median across Ardèche is 1,839 € per m², so this commune sits below it. ^[11]

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.
