Vitality score

Vitality score 33.8/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 43 % of the 14,087 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

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 16 days a year at or above 30 °C and 55 days at or below 0 °C, over 29 complete years in 1995–2024. [11]

Measured at the COURDIMANCHE weather station, 8.6 km away at 71 m; the village itself is at 71 m. [11]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. [11]

Humidity measured at COURDIMANCHE, 8.6 km away at 71 m, over 21 summers. [11]

An average of 663 mm of rain a year, spread over 114 days — about 5.8 mm on a day it rains. [11]

Rainfall measured at MILLY-LA-FORET, 3.1 km away at 109 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 Oncy-sur-École'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.
