May through October are the best listed months, while January, February, and December are toughest.

The air quality row is Excellent, while allergy levels are Poor. Long term fine particle pollution is 6.8 micrograms per cubic meter for the 2021 to 2025 modeled average.

Harrisburg in everyday life

Could Harrisburg work for you?

What may work well

  • Harrisburg has an 85°F average summer high, a 24°F average winter low, and 1,424 peak sun hours in the climate display.
  • Harrisburg’s air rows provide planning information, but the Poor allergy label remains visible beside Excellent air quality and the modeled fine particle line.
  • The best months align with Riverfront Park, City Island, the Greenbelt, the Capitol, the museum, and family visits.

What to think about

  • An 85°F summer high and 23 days above 90 make cooling, shade, water, and indoor options important.
  • Humidity is 78 percent and allergy levels are Poor, so ventilation and personal sensitivity matter.
  • A 24°F winter low and 120 freezing days make heating, pipes, parking, entry surfaces, and route planning important.

Plan Harrisburg around humidity, storms, and winter as well as the middle season

  1. Visit in a warm month and a cold month

    Notice cooling, ventilation, shade, pollen, humidity, heating, windows, entry surfaces, flood preparation, parking, and the route from the home to care, groceries, parks, and the river.

  2. Price climate inside the home

    Ask about cooling, heating, insulation, pipes, roof, windows, moisture, power, insurance, maintenance, and the household’s plan for 23 days above 90 and 120 freezing days.

  3. Pair outdoor and indoor choices

    Compare Riverfront Park, City Island, Reservoir Park, the Greenbelt, the Capitol, the National Civil War Museum, indoor cultural places, care, and family visits.

  4. Keep climate and hazard fields distinct

    Use Excellent air quality, 6.8 micrograms per cubic meter modeled fine particle pollution, Poor allergies, Moderate climate heat risk, Low drought risk, Limited volatility, and High safety flood and storm rows separately.
