Better served than 79 % of the 17,546 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 39 days a year at or above 30 °C and 3 days at or below 0 °C, over 12 complete years in 1995–2024. ^[12]

Measured at the FITOU weather station, 5.2 km away at 9 m; the village itself is at 112 m. ^[12]

The village sits 103 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 25 days a summer. ^[12]

Humidity measured at LEUCATE, 9.4 km away at 42 m, over 30 summers. ^[12]

That station sits 70 m below 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 501 mm of rain a year, spread over 57 days — about 8.8 mm on a day it rains. ^[12]

Rainfall measured at FITOU, 5.2 km away at 9 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
