Local Environmental Conditions
This site in Forest Grove is surrounded mainly by woodland, which covers around 100% of the nearby area. A watercourse nearby means riverside vegetation is part of the local pollen picture. Locally, the surrounding woods make trees an important source. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Tree pollen comes first, peaking in mid-spring. Grass pollen follows, peaking in early summer and easing off by mid-fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

Does pollen in Forest Grove come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Forest Grove 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 Forest Grove, 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.

| 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. |
