Local Environmental Conditions
The area around this location in Duluth is mostly woodland, with some open grassland and built-up land. A nearby park adds mown lawns and planted trees to the local pollen mix. The allergenic tree mix nearby includes willow and maple. Grass pollen adds noticeably to the overall load. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Willow and maple lead the season in mid-spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by late summer. A smaller weed peak follows from early summer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.

Does pollen in Duluth 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 Duluth 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 Duluth, 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.
