Beaverton, Oregon sits in the Willamette Valley, a river valley influenced by Pacific Ocean moisture and diverse vegetation. This region experiences some of the highest grass pollen counts in the entire United States, with levels frequently exceeding 950 particles per cubic meter during peak season. This guide covers the main pollen types, seasonal patterns, recent trends, and effective management strategies to help Beaverton residents navigate the challenging 8-month allergy season.
Understanding Pollen Count in Beaverton
Pollen count measures the number of pollen grains per cubic meter of air, indicating allergen exposure levels. When counts exceed 190 particles per cubic meter, conditions are considered very high, triggering symptoms like sneezing, nasal congestion, itchy eyes, coughing, and difficulty breathing. In Beaverton, June grass pollen regularly exceeds this threshold by five times or more, significantly affecting quality of life.
Record-Breaking Pollen Levels in Beaverton
Beaverton faces exceptionally severe pollen challenges due to its location in Oregon's grass seed capital. In June 2024, the Willamette Valley recorded 1,300 particles per cubic meter of grass pollen, the highest measurement in over 25 years. The region produces over two-thirds of global grass seed and nearly all ryegrass seed for U.S. lawns, creating massive agricultural pollen sources that travel for miles.
- Ryegrass Pollen: Dominant allergen from agricultural fields; June levels routinely exceed 950 particles per cubic meter, the highest in the United States
- Tree Pollen: Peak occurs March through April with major contributors including alder, birch, oak, cedar, cottonwood, and Douglas fir
- Ragweed Pollen: Primary fall allergen reaching maximum levels in September, extending the allergy season into late autumn
Climate change has extended the allergy season by 26 days between 1970 and 2021, with earlier spring onset causing plants to produce higher pollen concentrations for longer periods. Allergists at Oregon Health & Science University report seeing more severe allergies every year, with pollen levels consistently breaking historical records.

- Late Winter/Early Spring (January to March): Juniper peaks in late January through March, followed by alder beginning in late February
- Spring (March to June): Peak tree pollen season with oak, birch, maple, ash, cottonwood, and sycamore; May sees overlap of tree and grass pollen making it one of the worst overall months
