Confidence: high.

Better served than 86 % of the 10,687 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 59 days a year at or above 30 °C and 20 days at or below 0 °C, over 23 complete years in 1995–2024. ^[12]

Measured at the ROQUEBRUN weather station, 8.5 km away at 155 m; the village itself is at 259 m. ^[12]

The village sits 104 m above the station, so each day's reading was shifted by 5.7 °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 5 days a summer. ^[12]

Humidity measured at MURAT SUR VEBRE, 14.6 km away at 1,022 m, over 22 summers. ^[12]

That station sits 763 m above the village, so each day's humidity was shifted by 3.26 °C per km before the muggy days were counted. ^[12]

An average of 1,260 mm of rain a year, spread over 82 days — about 15.4 mm on a day it rains. ^[12]

Rainfall measured at OLARGUES, 6.2 km away at 182 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
