The climate of Pennsylvania (United
States of America)
The state of Pennsylvania is located in the northeastern part of the
United States. In the northwest Pennsylvania borders Lake Erie which
forms the natural border with Canada. In the east the Delaware River
forms the natural border with the states of New York and New Jersey.
The landscape of Pennsylvania is mainly dominated by the Appalachians
which is a large mountainous region in the eastern part of the United
States. Because of the presence of the Appalachians the landscape in
central Pennsylvania mainly consists of hills and low mountains. The
highest point in Pennsylvania is located at an altitude of 979 meters
above sea level.
Pennsylvania has a mix of a warm continental climate
(type Dfa according to the Köppen climate classification) and the
slightly cooler moderate continental climate (type Dfb) in both the
northern part of the state and in the Appalachians. Pennsylvania has
typical continental climate types instead of maritime climate types
because although the Atlantic Ocean is relatively nearby it hardly has
any influence on the climate and weather in Pennsylvania. The weather
in Pennsylvania is mainly determined by currents from the north and
the west. Fairly large differences in temperatures in the state of
Pennsylvania are not uncommon. In general, the northwestern part of
the state is slightly cooler than the eastern part of the state. The
difference in long term average temperatures is about 5 degrees
Celsius. Precipitation figures are about the same in the entire state.
Precipitation is also quite evenly spread out over the year, there are
no distinct dry or wet periods.
