Local Environmental Conditions
This site in Winona is surrounded mainly by woodland, which covers around 50% of the nearby area, with some wetland and open grassland. A stream or river nearby means riverside vegetation is part of the local pollen picture. The allergenic tree mix nearby includes oak, maple and mulberry. Beyond the trees, grasses matter a great deal, and ragweed is the main weed source.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, maple and mulberry are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Ragweed brings a final peak from late summer into mid-fall. Mold spores join in through summer, when damp, warm spells let them thrive. By late fall, pollen levels are low again.

Does pollen in Winona 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 Winona 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 Winona, 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.
