Richland's Columbia Basin Washington setting features sagebrush, cottonwood, and Russian olive as the main pollen sources, with exposure varying between the irrigated residential and Columbia River shoreline areas and the surrounding native shrub steppe. The Columbia River corridor is a particularly significant local source, while the stark contrast between the irrigated city vegetation and the surrounding sagebrush steppe landscape creates the most pronounced local pollen variation of any Washington State city.

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