Vitality score

Confidence: high.

Better served than 65 % of the 17,971 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 19 days a year at or above 30 °C and 53 days at or below 0 °C, over 16 complete years in 1995–2024. ^[11]

Measured at the ARBOIS weather station, 11.7 km away at 323 m; the village itself is at 221 m. ^[11]

The village sits 102 m below the station, so each day's reading was shifted by 5.55 °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 2 days a summer. ^[11]

Humidity measured at ARBOIS_SAPC, 12.2 km away at 313 m, over 21 summers. ^[11]

That station sits 92 m above the village, so each day's humidity was shifted by 3.06 °C per km before the muggy days were counted. ^[11]

An average of 1,157 mm of rain a year, spread over 141 days — about 8.2 mm on a day it rains. ^[11]

Rainfall measured at CHISSEY, 5.2 km away at 226 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
