On 16 July 2026, Grass is the dominant pollen source in Asheville. ambrosia are also present but at lower levels. oak, willow, alder, artemisia, birch, and cypress are not currently active.

Asheville's pollen season opens with oak and birch from late February, followed by pine through March and April. Grass pollen peaks through May and June, with ragweed extending the season into October. The Blue Ridge Mountain valley setting channels airflows and concentrates pollen, while surrounding Appalachian woodland contributes substantial tree pollen. Frequent mountain rainfall provides regular interruptions to exposure throughout the season.

The Asheville 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 Asheville, 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.
