North Aurora pollen forecast - today, tomorrow and the week ahead

On 9 August 2026, overall pollen levels in North Aurora are moderate. Artemisia is the main contributor to airborne pollen, while ambrosia remain at lower levels

On 10 August 2026, pollen conditions in North Aurora will be different from today, with grass at medium levels and artemisia, ambrosia increasing

According to the five-day outlook, artemisia, grass, and ambrosia pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

On 9 August 2026, Artemisia is the dominant pollen source in North Aurora. ambrosia are also present but at lower levels. cypress and grass are not currently active.

Trees along the Illinois River, such as willow and alder, are usually first to release pollen, typically peaking in late winter into March. Tree pollen peaks next around Rock Run Rookery Preserve, where oak and hickory dominate the canopy through most of April and May. Farther out toward the Spoon River and Starved Rock area woodlots, tree pollen tends to follow this same rough schedule.

The North Aurora pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 North Aurora, 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.
