Local Environmental Conditions
Clay's Onondaga County New York suburban setting features oak, maple, and birch as the main tree pollen sources, with exposure varying between the greener residential areas around Oneida Lake and the more built-up commercial corridors along Route 31. The Oneida Lake shoreline creates temperature-modifying effects, while the numerous Clay wetlands and Cicero Swamp corridor contribute distinctive wetland vegetation pollen and the flat Oneida Lake plain allows grass pollen to disperse widely throughout.
Clay's Central New York setting near Syracuse produces a season opening in late March with elm and maple before birch and oak peak through May. Grass from surrounding New York farmland peaks through June and July before mugwort and nettle extend exposure into September. The Oneida Lake proximity moderates temperatures locally, while the continental climate produces a well-defined seasonal progression 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. |
