Local Environmental Conditions
The nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees, within the neighborhood. Here, just around the area, a nearby park's turf and ornamental trees layer grass and ragweed pollen onto the seasonal mix. Seasonal timing here generally tracks the wider region, give or take a week or so.
Water-edge hazel and willow are usually the first allergenic trees active here, building through the tail end of winter into March. Grass pollen rises through late spring toward a June high point, and then ragweed picks up the slack, running from mid-August through October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

Does pollen in Arlington Heights 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 Arlington Heights 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 Arlington Heights, 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. |
