Average Snowfall in Philadelphia: What to Expect
Philadelphia, Pennsylvania, experiences moderate snowfall each winter. On average, the city sees around 22.4 inches of snow annually, though this can vary significantly from year to year.
Annual Snowfall Averages
The city’s average snowfall of 22.4 inches doesn’t tell the whole story. Some winters bring significantly more snow, while others are relatively mild. For example, the winter of 2009-2010 saw a record-breaking 78 inches of snowfall, while other years have barely reached double digits. The variability is due to several factors, including the track of winter storms and overall weather patterns.
Monthly Snowfall Breakdown
Snowfall in Philadelphia typically begins in December, with the highest averages occurring in January and February. Here’s a rough breakdown:
- December: Around 3-4 inches
- January: Around 6-8 inches
- February: Around 6-8 inches
- March: Around 2-4 inches (though snow is less common)
It’s important to remember that these are just averages, and actual snowfall can fluctuate greatly. For instance, a single nor’easter can dump a foot or more of snow on the city, drastically altering the monthly totals.
Factors Influencing Snowfall
Several factors determine the amount of snow Philadelphia receives each year.
Proximity to the Atlantic Ocean
Philadelphia’s proximity to the Atlantic Ocean makes it susceptible to nor’easters. These powerful coastal storms can bring heavy snow, strong winds, and coastal flooding.
Temperature
Temperature is another critical factor. For snow to fall, the air temperature needs to be at or below freezing (32°F or 0°C). However, even if the air temperature is slightly above freezing, snow can still fall if the ground temperature is cold enough.
Elevation
While Philadelphia is relatively flat, higher elevations to the north and west of the city often receive more snow due to cooler temperatures.
