The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 24, short of 90°F on every date, while 187 dates carry a normal low at or below freezing, the coldest 0°F near February 2.
The freezing stretch
The normal low stays at or below 32°F into April 27, then returns to freezing around October 24, covering 187 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.
The widest day
May 18 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Millinocket Wastewater Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 187 nights a year, more than most ranked stations.
Millinocket Wastewater earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Millinocket Wastewater spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 23%, with neither reaching the 35% that would mark a distinct wet season. Millinocket Wastewater has no dry season to plan around, though it does carry a wide 54°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 5.0" and February 2.7". The three wettest months together take 30% 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.

Data-derived climate profile
How Millinocket Wastewater's climate pattern fits together
heating led · wet · mid swing
Millinocket Wastewater's energy balance leans toward cold weather: 8,947 annual heating degree days against 236 for cooling. Its 54.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 135 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Millinocket Wastewater's middle-range seasonal profile. The measured spread is 54.0°F. The annual average is 41°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Millinocket Wastewater carries 46.1 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 Millinocket Wastewater'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 Millinocket Wastewater, 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 Millinocket Wastewater's primary station: MILLINOCKET WASTEWATER (USC00175305). 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 Millinocket Wastewater; 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 Millinocket Wastewater comes from its primary NOAA station record.
