Gillette's setting on the coal-country plains of northeast Wyoming supports shortgrass prairie, sagebrush flats, and cottonwood windbreaks as the leading local vegetation, all factoring into the pollen count through the year. Counts here rise and fall with the same broad rhythm as other places sharing this setting. Allergy sufferers in Gillette generally plan around this same recurring seasonal rhythm.

How often is the Gillette pollen forecast updated?
The Gillette pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Gillette 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 Gillette 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 Gillette, 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.
