Local Environmental Conditions
Nearby, a short distance from here, the waterway's edge supports hazel and willow, species known for potent, wind-carried pollen. Located in the wider area, this area has a stand of oak and birch, the latter ranked among the region's most potent tree allergens. This area, just around the area, has the park's turf and planted trees form a small but steady source of grass and ragweed pollen.
Along the waterway, hazel and willow release pollen first, usually peaking sometime between late winter and the end of March. Woodland oak and birch pick up the pace next, through mid-to-late spring, usually peaking from April into May. Moving into early summer, grass pollen climbs to its seasonal high in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

Does pollen in Chicago Ridge 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 Chicago Ridge 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 Chicago Ridge, 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. |
