ERIE, PA (ERIE INTERNATIONAL AIRPORT)

Overview:
Erie, situated on the Great Lake that has its name, has a temperate climate that is often influenced by lake effects. Lake breezes moderate temperatures in the fall and spring.

Average temperatures in February through April are often three to five degrees colder than Pittsburgh, which is only 125 miles to the south. Fall is normally the wettest season, with September and October the wettest two months of the year. Nearly 40 percent of Erie’s rainfall occurs from September through December. Lake-effect snow is common in the winter due to Erie’s location on Lake Erie. Amounts of over 100 inches of snow during the snow season are not uncommon.

Annual High and Low Temperature Departure

Cold Temperatures

¹Heating Degree Days (HDDs) are indexed units, not actual days, that roughly describe the demand to heat a building. HDDs accumulate on days colder than 65°F when heating is required. Every degree below 65°F is added to the annual total for an annual HDD value, which is plotted in the figure.

Hot Temperatures

²Cooling Degree Days (CDDs) are indexed units, not actual days, that roughly describe the demand to cool a building. CDDs accumulate on days warmer than 65°F when cooling is required. Every degree above 65°F is added to the annual total for an annual CDD value, which is plotted in the figure.
