Vitality score

Vitality score 24.8/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 35 % of the 16,902 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.

Measured but not scored in this model: Market. See the methodology for why.

Climate

An average of 36 days a year at or above 30 °C and 15 days at or below 0 °C, over 11 complete years in 1995–2024. ^[10]

Measured at the MAUVEZIN-SUR-GUPIE weather station, 5.9 km away at 95 m; the village itself is at 43 m. ^[10]

The village sits 52 m below the station, so each day's reading was shifted by 4.94 °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 9 days a summer. ^[10]

Humidity measured at MAUVEZIN-SUR-GUPIE, 5.9 km away at 95 m, over 11 summers. ^[10]

That station sits 52 m above the village, so each day's humidity was shifted by 5.46 °C per km before the muggy days were counted. ^[10]

An average of 769 mm of rain a year, spread over 118 days — about 6.5 mm on a day it rains. ^[10]

Rainfall measured at MAUVEZIN-SUR-GUPIE, 5.9 km away at 95 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

What property sold for

31 houses sold between 2021 and 2025, at a median of 206,150 € — 926 € per m² of built surface. ^[11]

The median across Lot-et-Garonne is 1,182 € 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.
