Climate

Measured at the TREMEUR weather station, 7.2 km away at 69 m; the village itself is at 150 m. ^[12]

The village sits 81 m above the station, so each day's reading was shifted by 5.71 °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 TREMEUR, 7.2 km away at 69 m, over 12 summers. ^[12]

That station sits 81 m below the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[12]

An average of 755 mm of rain a year, spread over 130 days — about 5.8 mm on a day it rains. ^[12]

Rainfall measured at TREMEUR, 7.2 km away at 69 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]
