Like any state with a variable terrain that includes mountains, Pennsylvania weather varies with the locale. Even in a specific region like Central Pennsylvania, you will find geography and climate variables. However, some generalizations hold true. Pennsylvania offers a distinctive four-season climate with glorious springs and autumns, warm and somewhat humid summers, and winter snow. January is the coldest month with an average high temperature in the mid 20s. July is the warmest month with average high temperatures near 80 degrees, although temperatures as high as 90 are not uncommon in the southern portion of the state. Annual precipitation averages near 45 inches in the southern region as well as in the more mountainous areas.
