Climate

Measured at the CHATILLON-LE-DU weather station, 4.9 km away at 341 m; the village itself is at 235 m. ^[12]

The village sits 106 m below 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. ^[12]

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

Humidity measured at BESANCON, 10.6 km away at 306 m, over 30 summers. ^[12]

That station sits 71 m above the village, so each day's humidity was shifted by 3.06 °C per km before the muggy days were counted. ^[12]

An average of 1,128 mm of rain a year, spread over 141 days — about 8 mm on a day it rains. ^[12]

Rainfall measured at CHATILLON-LE-DU, 4.9 km away at 341 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
