Local Environmental Conditions
Farmland and open water share the area around this location in Sleepy Eye, plus some woodland. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. In the immediate area, the woodland makes trees an important source; open grassland and farmland add grass and weed pollen.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

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 Sleepy Eye 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 Sleepy Eye, 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.
