Vitality score

Vitality score 30.6/100 — Few services (model fr-v0.2).

Confidence: high.

Better served than 44 % of the 15,843 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.

Muggy days a summer 2.3

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 10 days a year at or above 30 °C and 26 days at or below 0 °C, over 30 complete years in 1995–2024. ^[10]

Measured at the ST NAZAIRE-MONTOIR weather station, 14.1 km away at 3 m; the village itself is at 4 m. ^[10]

Muggy days — a dew point at or above 18 °C — average 2 days a summer. ^[10]

Humidity measured at ST NAZAIRE-MONTOIR, 14.1 km away at 3 m, over 30 summers. ^[10]

An average of 883 mm of rain a year, spread over 126 days — about 7 mm on a day it rains. ^[10]

Rainfall measured at SAVENAY, 5.5 km away at 11 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 Lavau-sur-Loire'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.
