Yellowstone National Park is a volcanic plateau with lodgepole pine forest and geothermal meadows. Pine pollen is significant in June and July. Meadow grasses around the geyser basins add to the mix. High elevation compresses the season into just two months.

How often is the Yellowstone pollen forecast updated?

Does pollen in Yellowstone 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 Yellowstone 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 Yellowstone, 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.
