Pullman sits on the rolling wheat country of the Palouse, where the dominant vegetation is a mix of wheat and canola fields, Ponderosa pine on the campus grounds, and native prairie grasses, shaping the local pollen profile across the seasons. Exposure varies with proximity to green space versus the more built-up parts of Pullman. The mix of native and introduced species here is fairly typical for this part of the country.

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