Local Environmental Conditions
The area around the center of Waukegan is mostly built-up land, with a good deal of woodland and some open grassland. With Surrounding Lake nearby, lakeside vegetation along its shore contributes to the local mix. The key allergenic tree nearby is oak. Grasses also feature strongly, alongside mugwort among the weeds.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak is in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Mugwort brings a final peak from midsummer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, pollen levels are low again.

How often is the Waukegan pollen forecast updated?
The Waukegan pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Waukegan 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 Waukegan 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 Waukegan, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
