Acadia National Park Monthly Climate Normals, Average Temperature, and Precipitation Data

Name: Acadia National Park monthly climate normals
Creator: NASA POWER

Explore long-term atmospheric patterns at Acadia National Park through twelve-month averages including temperature, precipitation, humidity, wind, and daylight. These climate normals represent a specific coordinate and observation period from 1991 to 2020. This data provides a consistent baseline for analyzing the annual rhythm of the park landscape, rather than current weather or immediate forecasts.

Acadia National Park Weather by Month: Complete Twelve Month Climatology

A representative coordinate at 38 meters elevation provides historical averages from 1991 through 2020 to trace the progression of monthly temperature bounds and average daily precipitation rates. Comparing individual monthly cycles rather than a single annual average reveals how relative humidity, wind speed, and calculated daylight hours fluctuate across the coastal Maine landscape.
