Local Environmental Conditions
North Pullman — Forest where oak and birch make up much of the canopy, driving spring pollen counts; this sits positioned about 294m from the neighborhood. Mown grass and ornamental trees in a nearby park, adding to seasonal grass and ragweed pollen, just over 5 meters from the neighborhood. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Oak and birch in the woodland come next, through the heart of spring, cresting around April and May in the year's sharpest tree-pollen spike. Through late spring, grass pollen climbs steadily toward its June peak, and ragweed later takes the lead from mid-August through October. Year-to-year timing varies a little, though the general sequence stays fairly consistent here.

Does pollen in Dolton 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 Dolton 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 Dolton, 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. |
