Measured at the VICHERES weather station, 9.3 km away at 235 m; the village itself is at 184 m. ^[11]

The village sits 51 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 VICHERES, 9.3 km away at 235 m, over 19 summers. ^[11]

That station sits 51 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 861 mm of rain a year, spread over 132 days — about 6.5 mm on a day it rains. ^[11]

Rainfall measured at AUTHON, 4.5 km away at 233 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
