Climate

Measured at the ST MICHEL MAUR_SAPC weather station, 0.6 km away at 698 m; the village itself is at 754 m. ^[10]

The village sits 56 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 ST MICHEL MAUR_SAPC, 0.6 km away at 698 m, over 16 summers. ^[10]

That station sits 56 m below 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 766 mm of rain a year, spread over 101 days — about 7.6 mm on a day it rains. ^[10]

Rainfall measured at ST MICHEL MAUR_SAPC, 0.6 km away at 698 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

What property sold for

17 houses sold between 2021 and 2025, at a median of 129,000 € — 1,873 € per m² of built surface. ^[11]

6 flats sold over the same window, at a median of 94,405 € — 1,706 € per m². ^[11]

The median across Savoie is 2,827 € per m², so this commune sits below it. ^[11]

These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
