Fayetteville sits in the Ozark region of Northwest Arkansas, where wooded landscapes, pastures, and urban lawns provide varied pollen sources. Seasonal weather supports cedar and juniper pollen in late winter, hardwood pollen in spring, and grass and weed pollen through summer and fall. Overlapping seasons can make it difficult to identify what is triggering symptoms. This guide explains Fayetteville’s main allergens, seasonal patterns, daily reporting options, and practical ways to manage exposure.
A pollen count describes the concentration of airborne pollen, usually measured by collecting and identifying grains from sampled air and reporting grains per cubic meter. Some Fayetteville reporting services publish category ratings or indexes instead of numerical concentrations, so their labels are not necessarily comparable. When relevant pollen levels rise, sensitive people may experience sneezing, congestion, a runny nose, and itchy or watery eyes.
Fayetteville’s main pollen concerns are cedar and juniper, spring hardwoods, grasses, and ragweed. In research checked October 20, 2026, the latest dated Hedberg Allergy & Asthma Center report, from October 19, listed moderate ragweed, moderate grass, low tree pollen, and low other weed pollen. It also reported very high mold, which is a separate airborne allergen.
A March 2025 Northwest Arkansas report citing Climate Central identified 13 additional freeze-free days since 1970, based on temperature analysis through 2024. This suggests a longer potential growing and allergy season, but does not establish 13 additional days of measured pollen. An accessible, continuous Fayetteville pollen record was not available to support a reliable local percentage increase.
Use these approximate seasonal ranges for planning, remembering that weather can shift pollen activity by several weeks.
Use the Pollen Count & Alerts App for daily monitoring and real-time tracking of tree, grass, and weed pollen, alongside mold spores as a separate allergen category. Check each update’s date and available location details, and compare reports with your known sensitivities. Local category ratings and forecast indexes should not be treated as equivalent to directly measured pollen concentrations.
Combine current allergen information with simple exposure-reduction habits and care tailored to your symptoms.
The Pollen Count & Alerts App brings together monitoring, alerts, forecasts, and educational information to support your daily allergy routine.

Pollen season in Fayetteville can begin in January with cedar and juniper, with eastern redcedar typically strongest in February–March. Spring tree pollen runs mainly from February through May, including elm and maple early in the season and oak peaking around April. Grasses contribute from April through September, sometimes into October, while ragweed is mainly active from August through October until a killing freeze. Trees and grasses often overlap in April–May, and grasses and weeds overlap in August–September, though weather can shift these periods by several weeks.
Important sources include eastern redcedar, typically strongest in February–March, and hardwoods such as American elm, red maple and boxelder, generally strongest in March–April. Post oak, white oak, northern red oak, blackjack oak and mulberry contribute spring pollen, usually peaking around April, while hickory, pecan and black walnut are active in April–May. Cool-season grasses such as tall fescue, orchardgrass, perennial ryegrass and timothy usually peak in May–June; Bermudagrass and Johnsongrass are generally strongest in June–August. Common and giant ragweed, along with pigweed and marsh elder, contribute late-season pollen, with the strongest periods generally in August–September.
Check the date and allergen categories on a Fayetteville-area pollen report before visiting parks, working in the yard or spending time near pastures, and use the Pollen Count & Alerts App to help plan around your sensitivities. When your trigger pollen is elevated, keep windows closed and reduce time near freshly cut grass or weedy roadsides. After outdoor activities, change clothes and shower to help remove pollen.
Fayetteville’s cedar, hardwoods, grasses and ragweed create pollen challenges across much of the year. Understanding their seasonal patterns and using the Pollen Count & Alerts App can help you make informed choices about outdoor activities and daily exposure.
