Local Environmental Conditions
Here, near this part of town, the tree cover here leans heavily on oak and birch, both key drivers of spring pollen. The broader area tends to mirror this pattern, with only minor local variation. Seasonal timing here generally tracks the wider region, give or take a week or so.
Woodland oak and birch pick up the pace next, through mid-to-late spring, peaking in the heart of spring, generally April into May. Through late spring, grass pollen climbs steadily toward its June peak, handing off to ragweed, which peaks from mid-August through October. This general pattern holds fairly steady across the surrounding county from year to year.

This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
