How to connect?

Set on the northern edge of the Black Hills, Sturgis's landscape is defined by ponderosa pine alongside bur oak and prairie grassland, the main contributors to seasonal pollen exposure. Exposure varies with proximity to green space versus the more built-up parts of Sturgis. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

How often is the Sturgis pollen forecast updated?

Does pollen in Sturgis 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 Sturgis 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 Sturgis, 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.
