Vitality score
Vitality score 47.8/100 — Partly served (model fr-v0.2).
Confidence: medium (sources disagree on Grocery (épicerie / supérette)).
Better served than 31 % of the 4,250 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 13 days a year at or above 30 °C and 40 days at or below 0 °C, over 30 complete years in 1995–2024. [10]
Measured at the VERSAILLES- INRAE weather station, 8.5 km away at 121 m; the village itself is at 28 m. [10]
The village sits 93 m below the station, so each day's reading was shifted by 5.71 °C per km of altitude before the days were counted. Expect the result to be within about 0.68 °C. [10]
Muggy days — a dew point at or above 18 °C — average 2 days a summer. [10]
Humidity measured at VERSAILLES- INRAE, 8.5 km away at 121 m, over 17 summers. [10]
That station sits 93 m above the village, so each day's humidity was shifted by 4.22 °C per km before the muggy days were counted. [10]
An average of 663 mm of rain a year, spread over 117 days — about 5.7 mm on a day it rains. [10]
Rainfall measured at LE PECQ, 1.1 km away at 27 m. Rainfall is not adjusted for altitude: unlike temperature it has no simple gradient to correct by. [10]
Uncertainties
sources disagree on Grocery (épicerie / supérette)
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 Le Port-Marly'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.
