NEW JERSEY – Newark, Jersey City, Trenton and Atlantic City face another winter season in which warmer weather does not necessarily mean fewer disruptions. New Jersey's historical statewide annual snowfall average stands at approximately 27.34 inches, reflecting weather station averages rather than one city's snowfall. El Niño does not eliminate snowstorms, dangerous cold or travel disruptions, which remain possible through March 2027.
According to the National Oceanic and Atmospheric Administration NOAA , its October 15, 2026, outlook favors above normal temperatures across New Jersey from December through February, with probabilities generally around 40% to 50%. Above normal precipitation is also favored, particularly near the coast. These seasonal probabilities do not predict snowfall totals or individual storms.
What New Jersey's Snowfall History Actually Shows New Jersey's 27.34 inch statewide historical average conceals significant geographic differences.
Northern communities around Sussex County and the Highlands generally experience colder, snowier winters than coastal locations near Atlantic City and Cape May.
NOAA's historical El Niño snowfall composites show varying outcomes across the Mid Atlantic, reflecting differences in storm tracks and temperatures.
No directly comparable statewide El Niño snowfall average is established by those composites.
Below average snowfall does not mean insignificant snowfall.
Why El Niño Doesn't Guarantee an Easy Winter El Niño influences Pacific temperatures and the jet stream, potentially redirecting winter storms across the eastern United States.
For New Jersey, coastal nor'easters are particularly important. Atlantic moisture interacting with cold inland air can produce heavy snow, while warmer ocean air brings rain or mixed precipitation closer to the shoreline.
The Interstate 80 corridor and northwestern elevations may experience snow while coastal communities receive rain.
Freezing rain, Arctic cold outbreaks and rapid temperature changes can also create hazardous conditions during otherwise warmer winters.
What This Means Through March Travelers along Interstate 95 and the New Jersey Turnpike, Interstate 80 and the Garden State Parkway should remain prepared for snow covered roads, freezing bridges and reduced visibility.
Newark area commuters, central New Jersey travelers and Jersey Shore residents face different hazards depending on storm tracks.
NOAA's December through February outlook does not cover March, when late season coastal storms can still bring accumulating snow.
El Niño changes seasonal probabilities, but it does not guarantee New Jersey a snow free or disruption free winter.
