Measured at the VIEU weather station, 2.8 km away at 616 m; the village itself is at 712 m. ^[12]

The village sits 96 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 0 days a summer. ^[12]

Humidity measured at LA BALME SUR CERDON_SAPC, 5.6 km away at 596 m, over 12 summers. ^[12]

That station sits 116 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 1,609 mm of rain a year, spread over 140 days — about 11.5 mm on a day it rains. ^[12]

Rainfall measured at VIEU, 2.8 km away at 616 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
