Vitality score
Vitality score 51.8/100 — Partly served (model fr-v0.2).
Confidence: high.
Better served than 62 % of the 6,455 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
An average of 1 day a year at or above 30 °C and 6 days at or below 0 °C, over 30 complete years in 1995–2024. [10]
Measured at the SAINT-CAST-LE-G weather station, 2.2 km away at 35 m; the village itself is at 52 m. [10]
Muggy days — a dew point at or above 18 °C — average 1 day a summer. [10]
Humidity measured at SAINT-CAST-LE-G, 2.2 km away at 35 m, over 21 summers. [10]
An average of 713 mm of rain a year, spread over 126 days — about 5.7 mm on a day it rains. [10]
Rainfall measured at SAINT-CAST-LE-G, 2.2 km away at 35 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [10]
What property sold for
383 houses sold between 2021 and 2025, at a median of 350,000 € — 3,077 € per m² of built surface. [11]
269 flats sold over the same window, at a median of 173,000 € — 4,250 € per m². [11]
The median across Côtes-d'Armor is 1,539 € per m², so this commune sits above it. [11]
These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
Uncertainties
The market day comes from the commune's own website and has not been confirmed by a second source. [5]

…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 Saint-Cast-le-Guildo'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.
