Measured at the CALVI weather station, 6.8 km away at 57 m; the village itself is at 366 m. ^[11]

The village sits 309 m above the station, so each day's reading was shifted by 4.13 °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 2 days a summer. ^[11]

Humidity measured at CALVI, 6.8 km away at 57 m, over 29 summers. ^[11]

That station sits 309 m below the village, so each day's humidity was shifted by 5.63 °C per km before the muggy days were counted. ^[11]

An average of 633 mm of rain a year, spread over 64 days — about 9.9 mm on a day it rains. ^[11]

Rainfall measured at CALVI, 6.8 km away at 57 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]
