The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 18, short of 90°F on every date, while 143 dates carry a normal low at or below freezing, the coldest 14°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around November 18, covering 143 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is May 18, when 43% of years recorded at least a hundredth of an inch. The driest is August 23 at 30%. Summed across the calendar, that is about 139 wet dates a year.
The widest day
June 7 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Acadia National Park Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 20°F.
The normal water year runs well above the national norm at roughly 56 inches.

Acadia National Park spreads its precipitation across the year
Neither half of the year dominates here: June through August take 20% of the annual total and December through February 25%, with neither reaching the 35% that would mark a distinct wet season. Acadia National Park has no dry season to plan around, though it does carry a wide 45.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: November averages 5.9" and July 3.3". The three wettest months together take 31% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Acadia National Park, it arrives in quantity
55.5" of precipitation falls across only about 139 wet days here, averaging 0.40 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 139 a year, 38% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days
- December, about 14
- Fewest wet days
- August, about 9
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Acadia National Park's climate pattern fits together
heating led · wet · mid swing
Acadia National Park's energy balance leans toward cold weather: 6,835 annual heating degree days against 411 for cooling. Its 45.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Acadia National Park's frost-free season lasts about 178 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Acadia National Park's middle-range seasonal profile. The measured spread is 45.9°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Acadia National Park carries 55.5 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Acadia National Park's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Acadia National Park, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Acadia National Park's primary station: ACADIA NP (USC00170100). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Acadia National Park; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Acadia National Park comes from its primary NOAA station record.
