More Information About Long Island Weather
Long Island has a climate that is very similar to other coastal areas of the Northeastern United States; it has warm, humid summers and cold winters, but the Atlantic Ocean helps bring afternoon sea breezes that temper the heat in the warmer months and limit the frequency and severity of thunderstorms. In the wintertime, temperatures are warmer than areas further inland (especially in the night and early morning hours), sometimes causing a snowstorm further inland to fall as rain on the island. However, measurable snow falls every winter, and in many winters one or more intense storms called nor'easters produce blizzard conditions with snowfalls of 1-2 feet and near-hurricane force winds.
Temperatures in Nassau and Suffolk are similar. The winter average for Nassau is 33.7 degrees Fahrenheit, compared to a summer average of 72.7 degrees. In Suffolk, the winter average is 32.4 and summer average is 71.9 degrees.
The Nassau area receives about 45 inches of rain, compared to 42 inches for Suffolk. Snow falls at about 26.9 inches per year in Nassau and 30 inches for Suffolk.
