Local Environmental Conditions
Burnsville's Minnesota River valley setting features oak, basswood, and cottonwood as the main tree pollen sources, with exposure varying between the wooded Minnesota Valley National Wildlife Refuge bluffs and the more built-up commercial corridors along County Road 42. The Minnesota River bottomland corridor is a particularly significant local source, while the distinct bluff-to-river topographic gradient creates measurable pollen exposure differences between the upland residential and river valley areas.
Burnsville'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 valley channels airflows, while the continental climate produces a well-defined seasonal progression ending earlier than in more southern US cities.

When is pollen season in Burnsville?
How often is the Burnsville pollen forecast updated?
The Burnsville pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Burnsville 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 Burnsville 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 Burnsville, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
