Climate

Measured at the BELLEY weather station, 3.9 km away at 330 m; the village itself is at 237 m. ^[13]

The village sits 93 m below 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. ^[13]

Muggy days — a dew point at or above 18 °C — average 3 days a summer. ^[13]

Humidity measured at BELLEY, 3.9 km away at 330 m, over 23 summers. ^[13]

That station sits 93 m above the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[13]

An average of 1,117 mm of rain a year, spread over 116 days — about 9.6 mm on a day it rains. ^[13]

Rainfall measured at BELLEY, 3.9 km away at 330 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[13]
