Does It Snow on Long Island?

Long Island’s climate is influenced by the surrounding Atlantic Ocean and Long Island Sound, which help moderate winter temperatures. As a result, snowfall totals are often lower than in many inland areas of New York, although significant winter storms can still produce substantial accumulations.

Snowfall varies across the island. Western Nassau County often experiences more mixed precipitation and rain during coastal storms, while central and eastern Suffolk County are more likely to receive heavier snowfall when temperatures remain below freezing.

Major nor’easters occasionally bring heavy snow, strong winds, coastal flooding, and travel disruptions. Local governments and transportation agencies are well equipped to respond with snow removal, road treatment, and public safety operations when significant winter weather occurs.

Although snow is a regular part of winter on Long Island, conditions can change quickly. Some winters feature several major storms, while others bring only occasional light snow or mostly rain.
