Local Environmental Conditions
Built-up land and woodland share the area around University Park, Illinois, plus some open grassland. With the Kankakee River nearby, riverside vegetation along its banks contributes to the local mix. Oak and maple are among the allergenic trees nearby. Grasses are a major source, with ragweed adding to the weed pollen load.
Oak and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in early summer and keep pollen in the air into early fall. Later, ragweed keeps weed pollen in the air from late summer into mid-fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.
