Allergy Shots in Pennsylvania: What to Know
Pennsylvania's ridge-and-valley topography traps pollen and mold across the state, driving Allentown to #11 on AAFA's allergy capitals list. Oak and ragweed dominate a pollen season stretching March through October, affecting roughly 2.6 million Pennsylvanians.
Top Allergens in Pennsylvania
The most common allergens affecting residents of Pennsylvania, ranked by severity and seasonal impact.
Oak (Quercus spp.)
SeverePA's dominant forest type is oak-hickory. Pittsburgh and Philadelphia both report oak as the dominant spring trigger. Season can extend from February in Philadelphia through May statewide.
Dominant spring tree allergen statewide
Hickory (Carya spp.)
SevereA defining Pennsylvania tree in the oak-hickory forest, hickory pollinates after the oak peak, extending tree-pollen exposure into late spring. Cross-reactive with walnut.
Extends tree pollen season into late spring
Ragweed
SeverePA's farmland (Lancaster County, Susquehanna Valley) and disturbed-soil habitats produce massive ragweed loads. Scranton's elevated weed-pollen score keeps it at or near the top of AAFA Allergy Capitals.
PA DEP runs a dedicated ragweed monitoring program
Timothy/Orchard Grass
SeverePennsylvania is a major hay-producing state where timothy and orchard grass dominate pasture and hayfield. Scranton scored above average for grass in AAFA 2024.
PA is a major hay-producing state
Birch/Maple
ModerateBirch is abundant in northern PA's Endless Mountains and Pocono Plateau. Red maple is the most widespread tree in PA, kicking off spring season as early as late February in Philadelphia.
Red maple is PA's most widespread tree
Cladosporium Mold
SeverePittsburgh's river-valley topography traps humidity and spores. Legacy PM2.5 amplifies allergic response. Eastern PA humidity drives summer mold peaks across the state.

Why Allergies Are Worse in Pennsylvania
Pennsylvania's parallel ridges create temperature inversions that trap pollen and mold in valleys, while the Susquehanna and Delaware valleys host dense ragweed populations. Industrial legacy particulates in Pittsburgh amplify allergic responses statewide.
Allegheny Ridge and Valley Pollen Trapping
Central PA's parallel ridges create temperature inversions in valleys that trap tree pollen and mold spores at ground level, concentrating exposure for residents in Scranton, Wilkes-Barre, State College, and Altoona.
Susquehanna and Delaware Valley Ragweed Belt
The fertile Susquehanna floodplain plus disturbed brownfield and industrial sites along major rivers host dense ragweed. PA DEP runs a dedicated ragweed monitoring program for the August-September peak.
Lake Erie Effect in NW Pennsylvania
Erie County's lake-driven humidity and fog promote year-round mold and extend ragweed season into mid-October due to delayed first frosts moderated by the lake.
Anthracite Coal Region and Pittsburgh Industrial Particulates
Legacy PM2.5 from steel and coal in the Monongahela Valley plus inversion-trapped sulfates give Allegheny County 20+ consecutive failing ALA air-quality grades, amplifying pollen and mold reactions.
