Dubuque's Mississippi River bluff setting in Iowa produces a season opening in late February with elm and maple before oak peaks through April. Grass from surrounding Iowa farmland peaks through June and July before mugwort and nettle extend exposure into September. The Mississippi River valley channels airflows, while the continental Midwest climate produces a well-defined seasonal progression throughout.

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 Dubuque, 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.
