Measured at the THONES weather station, 2 km away at 630 m; the village itself is at 699 m. ^[10]

The village sits 69 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. ^[10]

Muggy days — a dew point at or above 18 °C — average 0 days a summer. ^[10]

Humidity measured at LE GRAND-BORNAND, 16.7 km away at 1,430 m, over 19 summers. ^[10]

That station sits 731 m above the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[10]

An average of 1,784 mm of rain a year, spread over 132 days — about 13.5 mm on a day it rains. ^[10]

Rainfall measured at THONES, 2 km away at 630 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]
