Winner sits on open mixed-grass prairie in south-central South Dakota, where the dominant vegetation is a mix of mixed-grass prairie, wheat fields, and shelterbelt cottonwood, shaping the local pollen profile across the seasons. Local parks and open ground tend to see higher pollen counts than the denser urban core. The mix of native and introduced species here is fairly typical for this part of the country.

Does pollen in Winner 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 Winner 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 Winner, 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.
