Climate

An average of 11 days a year at or above 30 °C and 64 days at or below 0 °C, over 22 complete years in 1995–2024. ^[13]

Measured at the ST-PAUL-D'OUEIL weather station, 2.8 km away at 1,115 m; the village itself is at 963 m. ^[13]

The village sits 152 m below the station, so each day's reading was shifted by 5.7 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. ^[13]

Muggy days — a dew point at or above 18 °C — average 0 days a summer. ^[13]

Humidity measured at LUCHON, 5.4 km away at 618 m, over 30 summers. ^[13]

That station sits 345 m below the village, so each day's humidity was shifted by 3.26 °C per km before the muggy days were counted. ^[13]

An average of 1,026 mm of rain a year, spread over 121 days — about 8.5 mm on a day it rains. ^[13]

Rainfall measured at OO, 2.7 km away at 969 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[13]

What property sold for

9 houses sold between 2021 and 2025, at a median of 195,770 € — 2,628 € per m² of built surface. ^[14]

5 flats sold over the same window, at a median of 85,000 € — 1,771 € per m². ^[14]

The median across Haute-Garonne is 2,555 € per m², so this commune sits about level with it. ^[14]

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.
