Spokane, located in Eastern Washington, experiences a continental climate with four distinct seasons that create year-round pollen cycles. The city's warm, dry summers and diverse flora contribute to significant pollen challenges, particularly during spring and summer months. In 2026, Spokane ranked 9th on the Allergy Capitals report, a dramatic jump from 82nd place the previous year. This article covers Spokane's key pollen types, seasonal patterns, recent trends, and effective strategies for managing your allergies.
Pollen count measures the concentration of pollen grains per cubic meter of air, indicating allergy severity for residents. In Spokane, data is obtained from automated particulate sensors using neural network algorithms to identify individual pollen species. When pollen counts are high, common symptoms include sneezing, congestion, itchy eyes, and asthma exacerbations.
Spokane has experienced dramatic changes in pollen levels and patterns in recent years. After a wet winter in 2024-2025, trees produced unusually heavy pollen loads in spring 2025, with the Pacific Northwest facing the highest grass pollen levels in the country. Climate change projections suggest pollen production in North America could be 200% higher by the end of the century, with Spokane's spring pollen season potentially starting 10-40 days earlier.
Weather phenomena including atmospheric rivers, warmer temperatures, and extended growing seasons have contributed to the recent pollen explosion in Spokane. Suburban areas experience higher pollen counts than urban zones due to more green spaces and less pollution to trap airborne particles.
Spokane's four distinct seasons create predictable pollen cycles throughout the year.

Spokane experiences year-round pollen activity due to its four distinct seasons, with the highest levels from spring through fall. Tree pollen peaks in early spring (March-April) with alder, birch, willow, and oak, followed by intense grass pollen during summer months (June-August) featuring Timothy grass and ryegrass. Weed pollen, including ragweed and sagebrush, dominates the fall season (September-October), while winter (November-February) sees minimal pollen activity.
Spokane's primary allergens include tree pollen from willow, mulberry, pine, oak, cedar, alder, and birch peaking in spring; grass pollen from Timothy grass, ryegrass, Bermuda grass, orchard grass, and fescue dominating the summer months; and weed pollen from ragweed, sagebrush, Russian thistle, wormwood, pigweed, and nettles prevalent in fall. Timothy grass is considered the primary allergen during Spokane's peak summer pollen season, while sagebrush is particularly important in Eastern Washington's continental climate.
Pollen counts in Spokane peak during late morning to early afternoon, so outdoor activities are best scheduled for early morning or evening hours. Rising humidity, weak winds, and precipitation in the afternoon and evening help wash pollen from the air, making these times safer for allergy sufferers. The Pollen Count & Alerts App can provide real-time updates to help you plan your outdoor activities during lower pollen periods.
Living in Spokane means facing unique pollen challenges throughout the year, especially with the city's dramatic jump to 9th place on the 2026 Allergy Capitals report.
