Vitality score

Vitality score 32.4/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 58 % of the 16,798 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

Where this sits nationally

Days at or above 30 °C 2.5▸

Days at or below 0 °C 16.1▸

Muggy days a summer 0.7

Each track runs from the 5th to the 95th percentile of the 34,141 communes with that measurement; the tick is the median. A value beyond either end sits at the end and is marked ▸.

An average of 3 days a year at or above 30 °C and 16 days at or below 0 °C, over 30 complete years in 1995–2024. ^[10]

Measured at the SIZUN weather station, 8.2 km away at 157 m; the village itself is at 98 m. ^[10]

The village sits 59 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. ^[10]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[10]

Humidity measured at LANDIVISIAU, 15.4 km away at 109 m, over 30 summers. ^[10]

An average of 1,256 mm of rain a year, spread over 165 days — about 7.6 mm on a day it rains. ^[10]

Rainfall measured at HANVEC, 6.9 km away at 98 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[10]

…and in much the same climate

The same match on size and services, narrowed to communes whose summers, winters and summer humidity are all close to Le Tréhou's. All three are required, so this section is absent for the 11.8 % of communes with no humidity station near enough to measure: two temperature axes alone cannot tell a muggy coast from a dry one.
