Vitality score

Vitality score 29.5/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 73 % of the 17,933 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 2 days a year at or above 30 °C and 21 days at or below 0 °C, over 28 complete years in 1995–2024. ^[12]

Measured at the BRENNILIS weather station, 6 km away at 220 m; the village itself is at 159 m. ^[12]

The village sits 61 m below 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 ST-SEGAL S A, 16.6 km away at 89 m, over 29 summers. ^[12]

That station sits 70 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 1,458 mm of rain a year, spread over 173 days — about 8.4 mm on a day it rains. ^[12]

Rainfall measured at BRASPARTS, 5 km away at 145 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
