Vitality score

Confidence: high.

Better served than 46 % of the 17,755 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 3 days a year at or above 30 °C and 32 days at or below 0 °C, over 19 complete years in 1995–2024. ^[12]

Measured at the CAYEUX-SUR-MER weather station, 12.9 km away at 4 m; the village itself is at 72 m. ^[12]

The village sits 68 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. ^[12]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[12]

Humidity measured at CAYEUX-SUR-MER, 12.9 km away at 4 m, over 18 summers. ^[12]

That station sits 68 m below the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[12]

An average of 937 mm of rain a year, spread over 140 days — about 6.7 mm on a day it rains. ^[12]

Rainfall measured at FEUQUIERES-EN-VIMEU, 4.8 km away at 100 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]

What property sold for

17 houses sold between 2021 and 2025, at a median of 126,000 € — 1,200 € per m² of built surface. ^[13]

The median across Somme is 1,471 € per m², so this commune sits below it. ^[13]

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.
