Ranked from NOAA 1991-2020 Climate Normals
Wettest Counties in Pennsylvania
Total annual precipitation by county, wettest first. Rainfall drives roof and siding wear, basement water, and in much of the country the flood component of the insurance premium. Figures are NOAA 1991-2020 Climate Normals from the weather station nearest each county seat, so they describe a thirty-year average rather than any single year.

Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
