Eagan pollen forecast - today, tomorrow and the week ahead

On 16 July 2026, overall pollen levels in Eagan are moderate. Grass is the main contributor to airborne pollen

On 17 July 2026, pollen conditions in Eagan will be different from today, with grass continuing to decline

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

On 16 July 2026, Grass is the dominant pollen source in Eagan. willow, alder, ambrosia, artemisia, birch, cypress, and oak are not currently active.

Eagan's Twin Cities suburban setting in Minnesota produces a season opening in late March with elm and maple before birch and oak peak through May. Grass from surrounding Minnesota farmland peaks through June and July before mugwort and nettle extend exposure into September. The Minnesota River corridor channels airflows, while the continental climate produces a well-defined seasonal progression ending earlier than in more southern US cities.

The Eagan 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 Eagan, 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.
