Climate

Measured at the REVENTIN weather station, 10.1 km away at 295 m; the village itself is at 351 m. ^[11]

The village sits 56 m above the station, so each day's reading was shifted by 6.06 °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 REVENTIN, 10.1 km away at 295 m, over 21 summers. ^[11]

That station sits 56 m below the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[11]

An average of 785 mm of rain a year, spread over 96 days — about 8.2 mm on a day it rains. ^[11]

Rainfall measured at REVENTIN, 10.1 km away at 295 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
