Climate

An average of 15 days a year at or above 30 °C and 58 days at or below 0 °C, over 30 complete years in 1995–2024. ^[11]

Measured at the MAULE weather station, 4.7 km away at 33 m; the village itself is at 183 m. ^[11]

The village sits 150 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. ^[11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[11]

Humidity measured at CHAPET, 5.6 km away at 42 m, over 21 summers. ^[11]

That station sits 141 m below the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[11]

An average of 679 mm of rain a year, spread over 118 days — about 5.8 mm on a day it rains. ^[11]

Rainfall measured at MAULE, 4.7 km away at 33 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
