Bentonville's Northwest Arkansas Ozark setting produces a season opening in late January with cedar and elm before oak peaks through March and April. Grass from surrounding Arkansas Ozark farmland peaks through May and June before mugwort and nettle extend exposure into September. The Cedar Creek corridor channels airflows, while the cedar season from December through February is locally significant and the Ozark setting concentrates pollen in valley locations.

The Bentonville pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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 Bentonville, 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.
