Measured at the CLAIRFONTAINE weather station, 5 km away at 225 m; the village itself is at 160 m. ^[11]

The village sits 65 m below the station, so each day's reading was shifted by 5.71 °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 CLAIRFONTAINE, 5 km away at 225 m, over 12 summers. ^[11]

That station sits 65 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[11]

An average of 951 mm of rain a year, spread over 137 days — about 6.9 mm on a day it rains. ^[11]

Rainfall measured at LA BOUTEILLE, 3.7 km away at 133 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
