Vitality score

Vitality score 45.2/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 62 % of the 11,026 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 30.3

Days at or below 0 °C 46

Muggy days a summer 1.8

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 30 days a year at or above 30 °C and 46 days at or below 0 °C, over 23 complete years in 1995–2024. ^[11]

Measured at the LUZINAY weather station, 11.7 km away at 310 m; the village itself is at 300 m. ^[11]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[11]

Humidity measured at BOURGOIN, 18.8 km away at 358 m, over 20 summers. ^[11]

That station sits 58 m above the village, so each day's humidity was shifted by 3.69 °C per km before the muggy days were counted. ^[11]

An average of 915 mm of rain a year, spread over 111 days — about 8.2 mm on a day it rains. ^[11]

Rainfall measured at LUZINAY, 11.7 km away at 310 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[11]

…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 Grenay'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.
