Vitality score

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

Confidence: medium (sources disagree on Restaurant).

Better served than 73 % of the 12,015 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.

An average of 4 days a year at or above 30 °C and 26 days at or below 0 °C, over 30 complete years in 1995–2024. ^[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 Montmartin-sur-Mer'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.
