Local Environmental Conditions
Abington's Montgomery County Pennsylvania setting features oak, tulip poplar, and maple as the main tree pollen sources, with exposure varying between the wooded Abington Township residential areas and the more built-up commercial corridors along Old York Road. The Pennypack Creek corridor provides particularly significant local green space, while the rolling Montgomery County topography creates modest pollen gradients between the creek valley floor and the more elevated residential ridgelines throughout the season.
Abington's Philadelphia suburban setting in Pennsylvania produces a season opening in late February with cedar and elm before oak peaks through April. Grass from surrounding Pennsylvania farmland peaks through May and June before mugwort and nettle extend exposure into September. The Pennypack Creek corridor channels airflows, while the moderate mid-Atlantic climate advances the season compared to more northern Pennsylvania locations throughout.

Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
