Vitality score

Vitality score 47.9/100 — Partly served (model fr-v0.2).

Confidence: high.

Better served than 40 % of the 5,748 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 52 days at or below 0 °C, over 19 complete years in 1995–2024. [9]

Measured at the FLINS-SUR-SEINE weather station, 6.5 km away at 32 m; the village itself is at 25 m. [9]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. [9]

Humidity measured at MAGNANVILLE, 8.9 km away at 123 m, over 30 summers. [9]

That station sits 98 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. [9]

An average of 629 mm of rain a year, spread over 117 days — about 5.4 mm on a day it rains. [9]

Rainfall measured at FLINS-SUR-SEINE, 6.5 km away at 32 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [9]

…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 Mézières-sur-Seine'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.
