Local Environmental Conditions
Nearby, just around the area, moisture-loving hazel and willow dominate the bank, both quick to release pollen on the wind. A stand of oak and birch, the latter ranked among the region's most potent tree allergens; this sits within easy reach. The broader area tends to mirror this pattern, with only minor local variation.
Hazel and willow near the water open the pollen calendar early, usually peaking sometime between late winter and the end of March. Oak and birch in the woodland come next, through the heart of spring, generally peaking somewhere between April and May. As spring turns to summer, grass pollen rises toward its June high, handing off to ragweed, which peaks from mid-August through October.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Middle Paxton Township, modern forecasts combine recent measurements, weather data, and information about local vegetation.
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. |
