“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Atlantic
Atlantic gets 45 inches of rain and melted snow a year. August is the wettest month and February the driest. Rain or snow falls on about 120 days a year. Snow covers the ground about 10 days of the year.
About 240 frost-free days a year
In half of years the last 32° night comes by March 26 and the first one by November 21. That leaves about 240 frost-free days for gardens, longer than 88% of U.S. towns.
Heating and cooling a home in Atlantic
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Atlantic, 82% of that work is heating and 18% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
Atlantic and its neighbors
Atlantic borders 6 towns with climate data. January nights across them vary by 2.3°. Egg Harbor has both the coldest January nights (26°) and the hottest July afternoons (85°). Atlantic’s January low is 28° and its July high 83°.
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value.
How Atlantic compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Atlantic averaged 2.4° warmer than the 1900s. The biggest change is in December (+3.7°). The shift is larger than in 100% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. December swings the most: between 1991 and 2020 its average temperature ranged from 32° to 52°. September is the most reliable, staying within 7°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Atlantic itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Atlantic City Intl Airport, NJ (8 mi, snow) and Atlantic City, NJ (1 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
