Local Environmental Conditions
Fox Hills — Hazel and willow thrive along the damp bank, both prolific early wind-pollinators; this sits close by, around 317 meters away. Oak and birch dominating the treeline, both heavy contributors to the spring pollen load, within easy reach at 445m. Local readings for the surrounding area tend to follow this same general pattern.
Along the waterway, hazel and willow release pollen first, building through the tail end of winter into March. Woodland oak and birch pick up the pace next, through mid-to-late spring, cresting around April and May in the year's sharpest tree-pollen spike. As spring turns to summer, grass pollen rises toward its June high, with ragweed then rising to the fore from mid-August through October.

How often is the Rockford pollen forecast updated?

Does pollen in Rockford 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 Rockford 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 Rockford, 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. |
