Local Environmental Conditions
Absent nearby tree cover or a waterway, wild grass and ragweed growing on open land likely shape the local pollen profile most. Local readings for the surrounding area tend to follow this same general pattern. Ground-level conditions like local landscaping can nudge these figures slightly either way. Nearby weather stations report comparable trends across the broader stretch of the county.
By late spring, grass pollen is climbing steadily toward a June high point, followed by ragweed's own peak stretch from mid-August into October. Small variations in local weather can nudge these windows a few days in either direction. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

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. |
