Local Environmental Conditions
Here, just outside the immediate area, hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. The park's turf and planted trees form a small but steady source of grass and ragweed pollen, within the local area. As with most local readings, actual levels can vary somewhat with short-term weather swings.
Hazel and willow along the water get the season underway before other species, leading off the pollen calendar, with a peak generally falling in late winter. Grass pollen rises through late spring toward a June high point, handing off to ragweed, which peaks from mid-August through October. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

Does pollen in Washington Township, Pennsylvania come from nearby or far away?

Are pollen levels in Washington Township, Pennsylvania based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Washington Township, Pennsylvania, 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. |
