Climate

An average of 12 days a year at or above 30 °C and 97 days at or below 0 °C, over 27 complete years in 1995–2024. ^[11]

Measured at the CERNON weather station, 3.8 km away at 500 m; the village itself is at 659 m. ^[11]

The village sits 159 m above the station, so each day's reading was shifted by 5.55 °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 0 days a summer. ^[11]

Humidity measured at LA PESSE, 14.6 km away at 1,133 m, over 27 summers. ^[11]

That station sits 474 m above the village, so each day's humidity was shifted by 3.06 °C per km before the muggy days were counted. ^[11]

An average of 1,563 mm of rain a year, spread over 141 days — about 11.1 mm on a day it rains. ^[11]

Rainfall measured at CERNON, 3.8 km away at 500 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
