The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 22, short of 90°F on every date, while 250 dates carry a normal low at or below freezing, the coldest 0°F near January 7.
The freezing stretch
The normal low stays at or below 32°F into May 26, then returns to freezing around September 20, covering 250 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
July 9 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Atlantic City Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 250 nights a year, placing this among the most frost-prone tenth of ranked stations.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Atlantic City earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Atlantic City spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Atlantic City has no dry season to plan around, though it does carry a wide 45.2°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.6" and July 0.8". The three wettest months together take 34% 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 Atlantic City's climate pattern fits together
heating led · dry · mid swing
Atlantic City's energy balance leans toward cold weather: 10,393 annual heating degree days against 18 for cooling. Its 45.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Atlantic City. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
July and January mark the typical warm and cold ends of the calendar in Atlantic City's middle-range seasonal profile. The measured spread is 45.2°F. The annual average is 37°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Atlantic City's cold-season load does not imply a wet climate. Annual precipitation is 17.9 inches, which places the station in PlainClimate's dry range. Snowfall is not added to the interpretation because its annual value is missing. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
These labels group NOAA 1991-2020 normals from Atlantic City'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 Atlantic City, not an official NOAA class or a year-ahead forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Atlantic City's primary station: ATLANTIC CITY (USC00480432). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 5604015), not an incorporated municipality. Match rule for Atlantic City: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Atlantic City comes from its primary NOAA station record.
