The year, day by day
Summer here tops out rather than builds: the warmest normal high is 86°F around July 15, short of 90°F on every date, while 56 dates carry a normal low at or below freezing, the coldest 29°F near January 21.
The freezing stretch
The normal low stays at or below 32°F into February 18, then returns to freezing around December 25, covering 56 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
April 27 carries the biggest normal gap between afternoon and dawn, 17°F between the normal high and the normal low.

Where Annapolis Naf Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 17°F.
Annapolis Naf 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
Annapolis Naf spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Annapolis Naf has no dry season to plan around, though it does carry a 42.5°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.1" and February 2.4". The three wettest months together take 33% 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 Annapolis Naf's climate pattern fits together
heating led · moderate · mid swing
Annapolis Naf's energy balance leans toward cold weather: 4,062 annual heating degree days against 1,436 for cooling. Its 42.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
The frost-free window extends for about 242 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
July and January mark the typical warm and cold ends of the calendar in Annapolis Naf's middle-range seasonal profile. The measured spread is 42.5°F. The annual average is 58°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Annapolis Naf's 44.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Annapolis Naf'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 Annapolis Naf, 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 Annapolis Naf's primary station: ANNAPOLIS NAF (USW00013752). 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 Annapolis Naf; 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 Annapolis Naf comes from its primary NOAA station record.
