Vitality score

Vitality score 18.6/100 — No daily shops (model fr-v0.2).

Confidence: high.

Better served than 35 % of the 18,056 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.

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 13 days a year at or above 30 °C and 52 days at or below 0 °C, over 30 complete years in 1995–2024. ^[10]

Measured at the ESTERNAY weather station, 9.9 km away at 185 m; the village itself is at 190 m. ^[10]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[10]

An average of 743 mm of rain a year, spread over 123 days — about 6 mm on a day it rains. ^[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 Lachy'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.
