Confidence: high.

Better served than 71 % of the 17,659 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 44 days a year at or above 30 °C and 45 days at or below 0 °C, over 24 complete years in 1995–2024. ^[11]

Measured at the ALBA SA weather station, 10.1 km away at 223 m; the village itself is at 306 m. ^[11]

The village sits 83 m above the station, so each day's reading was shifted by 6.06 °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 4 days a summer. ^[11]

Humidity measured at ALBA SA, 10.1 km away at 223 m, over 23 summers. ^[11]

That station sits 83 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[11]

An average of 897 mm of rain a year, spread over 76 days — about 11.8 mm on a day it rains. ^[11]

Rainfall measured at ST-MONTAN, 3.1 km away at 130 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
