Blacksburg's Virginia Appalachian ridge and valley setting features oak, hickory, and maple as the main tree pollen sources, with exposure varying between the extensively forested Appalachian ridges surrounding the town and the more open New River valley floor university and commercial areas. The topographic setting creates distinct pollen gradients between the densely forested ridge slopes and the more open valley areas throughout the season.

Grass from surrounding Virginia farmland peaks through May and June before mugwort and nettle extend exposure into September. The New River valley setting concentrates pollen under calm conditions, while the elevated Appalachian setting means the season begins slightly later than in lower Virginia cities.
How often is the Blacksburg pollen forecast updated?

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

Does pollen in Blacksburg come from nearby or far away?

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.

Are pollen levels in Blacksburg based on measurements or forecasts?

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 Blacksburg, 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.
