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.
