Vitality score

Vitality score 16.3/100 — No daily shops (model fr-v0.2).

Confidence: high.

Better served than 88 % of the 2,868 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 19 days a year at or above 30 °C and 60 days at or below 0 °C, over 27 complete years in 1995–2024. ^[12]

Measured at the SEMUR EN AUXOIS_SAPC weather station, 12.5 km away at 314 m; the village itself is at 292 m. ^[12]

Muggy days — a dew point at or above 18 °C — average 1 day a summer. ^[12]

Humidity measured at SEMUR EN AUXOIS_SAPC, 12.5 km away at 314 m, over 12 summers. ^[12]

An average of 883 mm of rain a year, spread over 134 days — about 6.6 mm on a day it rains. ^[12]

Rainfall measured at MARIGNY LE CAHOUET, 5.5 km away at 335 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. ^[12]

…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 Brain'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.
