Confidence: high.

Better served than 93 % of the 8,714 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 135 days at or below 0 °C, over 27 complete years in 1995–2024. ^[10]

Measured at the LA FAURIE weather station, 12.5 km away at 825 m; the village itself is at 892 m. ^[10]

The village sits 67 m above the station, so each day's reading was shifted by 5.21 °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 LA FAURIE, 12.5 km away at 825 m, over 27 summers. ^[10]

That station sits 67 m below the village, so each day's humidity was shifted by 4.57 °C per km before the muggy days were counted. ^[10]

An average of 878 mm of rain a year, spread over 86 days — about 10.2 mm on a day it rains. ^[10]

Rainfall measured at SERRES, 7.4 km away at 652 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

What property sold for

9 houses sold between 2021 and 2025, at a median of 148,000 € — 1,537 € per m² of built surface. ^[11]

The median across Hautes-Alpes is 2,500 € 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.
