Local Environmental Conditions
This area, near this part of town, has a waterway supports hazel and willow along its bank, both strongly allergenic wind-pollinated species. This area, within the neighborhood, has woodland where oak stands alongside birch, the latter especially aggressive as an allergen. Located within the local area, this area has a nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix.
Water-edge hazel and willow are usually the first allergenic trees active here, starting well before the main spring rush, topping out around March. Once hazel fades, oak and birch in the woods carry the season forward, typically landing in April and May. By late spring, grass pollen is climbing steadily toward a June high point, before ragweed's late-summer surge carries the season into October.

How often is the Woodridge pollen forecast updated?

Does pollen in Woodridge 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 Woodridge 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 Woodridge, 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. |
