Confidence: high.

Better served than 33 % of the 17,846 communes of a similar size.

Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.

Climate

An average of 30 days a year at or above 30 °C and 33 days at or below 0 °C, over 21 complete years in 1995–2024. ^[11]

Measured at the AUZEVILLE-TOLOSANE-INRAE weather station, 3.4 km away at 150 m; the village itself is at 267 m. ^[11]

The village sits 117 m above 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. ^[11]

Muggy days — a dew point at or above 18 °C — average 6 days a summer. ^[11]

Humidity measured at AUZEVILLE-TOLOSANE-INRAE, 3.4 km away at 150 m, over 22 summers. ^[11]

That station sits 117 m below the village, so each day's humidity was shifted by 3.26 °C per km before the muggy days were counted. ^[11]

An average of 646 mm of rain a year, spread over 100 days — about 6.5 mm on a day it rains. ^[11]

Rainfall measured at AUZEVILLE-TOLOSANE-INRAE, 3.4 km away at 150 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]

What property sold for

10 houses sold between 2021 and 2025, at a median of 515,880 € — 2,522 € per m² of built surface. ^[12]

The median across Haute-Garonne is 2,555 € per m², so this commune sits about level with it. ^[12]

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.
