Muggy days — a dew point at or above 18 °C — average 3 days a summer. ^[12]

Humidity measured at BELLEY, 6.2 km away at 330 m, over 23 summers. ^[12]

That station sits 86 m above the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[12]

An average of 1,117 mm of rain a year, spread over 116 days — about 9.6 mm on a day it rains. ^[12]
