Climate

An average of 18 days a year at or above 30 °C and 97 days at or below 0 °C, over 15 complete years in 1995–2024. ^[11]

Measured at the CESSIEU weather station, 7.9 km away at 304 m; the village itself is at 510 m. ^[11]

The village sits 206 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 1 day a summer. ^[11]

Humidity measured at BOURGOIN, 10.4 km away at 358 m, over 20 summers. ^[11]

That station sits 152 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 1,012 mm of rain a year, spread over 112 days — about 9 mm on a day it rains. ^[11]

Rainfall measured at CESSIEU, 7.9 km away at 304 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
