Measured at the TIL-CHATEL_SAPC weather station, 12.8 km away at 283 m; the village itself is at 345 m. ^[12]

The village sits 62 m above 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 1 day a summer. ^[12]

Humidity measured at TIL-CHATEL_SAPC, 12.8 km away at 283 m, over 18 summers. ^[12]

That station sits 62 m below 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 924 mm of rain a year, spread over 134 days — about 6.9 mm on a day it rains. ^[12]

Rainfall measured at SAUSSY, 8.2 km away at 554 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
