Climate

An average of 28 days a year at or above 30 °C and 90 days at or below 0 °C, over 29 complete years in 1995–2024. ^[12]

Measured at the PONT-DE-BEAUVOISIN weather station, 9.7 km away at 284 m; the village itself is at 454 m. ^[12]

The village sits 170 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. ^[12]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[12]

Humidity measured at COUBLEVIE, 18.5 km away at 300 m, over 19 summers. ^[12]

That station sits 154 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[12]

An average of 1,117 mm of rain a year, spread over 120 days — about 9.3 mm on a day it rains. ^[12]

Rainfall measured at FAVERGES, 8.7 km away at 367 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
