Source: NOAA National Centers for Environmental Information U.S. Climate Normals v1.0.1 · 1991-2020 Statewide aggregates for Pennsylvania computed as the simple average across its 157 station-mapped locations, each represented by its primary NOAA station (293 stations in the state network).

Climate Insight: Pennsylvania

Pennsylvania's climate profile is aggregated from 157 station-mapped locations and 293 NOAA weather stations reporting under the 1991–2020 U.S. Climate Normals program. The statewide average annual temperature sits at 50°F, which is the simple average across all tracked station-mapped locations rather than any single station's reading. Because Pennsylvania spans multiple latitudes, elevations, and proximities to large water bodies, local conditions can differ from this headline number by wide margins; coastal, valley, and mountain stations often diverge by ten degrees or more even within a single month.

Precipitation and snowfall averages round out the climatological picture. Across Pennsylvania, annual precipitation averages 45.2 inches, with typical seasonal snowfall near 44.1 inches statewide. These numbers combine rain, sleet, and snow water-equivalent and describe the thirty-year normal rather than any particular recent year. Readers evaluating a specific destination should drill into one of the 157 individual location profiles below; each station record varies with local geography, and the statewide figures here are averages that mask meaningful intrastate differences.

For planning purposes, the location table above is sorted to help you compare averages side-by-side: annual mean temperature, average daily high and low, precipitation totals, snowfall, and PlainClimate's climate comfort score. That 1–100 score combines temperature mildness, precipitation moderation, snowfall burden, and frost-free growing-season length from each location's NOAA normal. It is a climate-only comparison, not a NOAA or overall livability rating. Use it as a starting point, then open each location profile for the exact score inputs, monthly breakdowns, degree-day totals, frost dates, and separately reported humidity metrics.

Frequently Asked Questions

What is the average temperature in Pennsylvania?
Pennsylvania averages 50°F a year across NOAA's 1991-2020 Climate Normals, cooler than 60% of U.S. states. That is 2.9°F below the 53.1°F average across all 50 states.
Does the climate vary a lot within Pennsylvania?
Yes. Annual averages inside Pennsylvania run from Oswayo at 44°F to Phila Franklin Inst at 58°F -- a 14°F spread between the state's coldest and warmest measured station-mapped locations. A single statewide average can mask this kind of local variation.
Where does Pennsylvania rank nationally for temperature?
Pennsylvania ranks #30 warmest and #21 coldest out of 50 U.S. states and territories with NOAA normals data, based on statewide average annual temperature.
What is the most comfortable station-mapped location in Pennsylvania?
Harrisburg Cptl CY scores the highest established comfort rating in Pennsylvania at 80/100, a PlainClimate composite of annual temperature mildness, precipitation moderation, snowfall burden, and frost-free growing-season length.
