Vitality score

Confidence: high.

Better served than 62 % of the 17,521 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 31 days a year at or above 30 °C and 23 days at or below 0 °C, over 22 complete years in 1995–2024. ^[12]

Measured at the IROULEGUY weather station, 6.3 km away at 229 m; the village itself is at 124 m. ^[12]

The village sits 105 m below the station, so each day's reading was shifted by 4.94 °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 14 days a summer. ^[12]

Humidity measured at BUSTINCE - ST JEAN, 11.1 km away at 189 m, over 21 summers. ^[12]

That station sits 65 m above the village, so each day's humidity was shifted by 5.46 °C per km before the muggy days were counted. ^[12]

An average of 1,450 mm of rain a year, spread over 137 days — about 10.6 mm on a day it rains. ^[12]

Rainfall measured at IROULEGUY, 6.3 km away at 229 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
