Climate

Measured at the AVALLON weather station, 9.6 km away at 245 m; the village itself is at 139 m. ^[11]

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. ^[11]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[11]

Humidity measured at AVALLON, 9.6 km away at 245 m, over 11 summers. ^[11]

That station sits 106 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 840 mm of rain a year, spread over 126 days — about 6.7 mm on a day it rains. ^[11]

Rainfall measured at BOIS-D ARCY, 5.3 km away at 210 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
