Vitality score

Vitality score 32.9/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 74 % of the 18,020 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 4 days a year at or above 30 °C and 24 days at or below 0 °C, over 30 complete years in 1995–2024. ^[11]

Measured at the ST-SEGAL S A weather station, 1.7 km away at 89 m; the village itself is at 21 m. ^[11]

The village sits 68 m below the station, so each day's reading was shifted by 5.71 °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 1 day a summer. ^[11]

Humidity measured at ST-SEGAL S A, 1.7 km away at 89 m, over 29 summers. ^[11]

That station sits 68 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. ^[11]

An average of 1,125 mm of rain a year, spread over 153 days — about 7.4 mm on a day it rains. ^[11]

Rainfall measured at ST-SEGAL S A, 1.7 km away at 89 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]

What property sold for

47 houses sold between 2021 and 2025, at a median of 102,450 € — 1,075 € per m² of built surface. ^[12]

20 flats sold over the same window, at a median of 71,780 € — 821 € per m². ^[12]

The median across Finistère is 1,821 € per m², so this commune sits below 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.
