Vitality score

Confidence: high.

Better served than 40 % of the 14,079 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 14 days a year at or above 30 °C and 31 days at or below 0 °C, over 13 complete years in 1995–2024. ^[11]

Measured at the LE PLESSIS GASSOT weather station, 9.1 km away at 108 m; the village itself is at 76 m. ^[11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[11]

Humidity measured at ST WITZ, 12 km away at 141 m, over 17 summers. ^[11]

That station sits 65 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 731 mm of rain a year, spread over 119 days — about 6.1 mm on a day it rains. ^[11]

Rainfall measured at LE PLESSIS GASSOT, 9.1 km away at 108 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]

What property sold for

52 houses sold between 2021 and 2025, at a median of 350,000 € — 3,057 € per m² of built surface. ^[12]

15 flats sold over the same window, at a median of 160,000 € — 3,082 € per m². ^[12]

The median across Val-d'Oise is 3,609 € per m², so this commune sits below 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.
