Glens Falls's Adirondack foothills Hudson Valley setting features paper birch, maple, and oak as the main tree pollen sources, with exposure varying between the wooded Adirondack foothills residential areas to the north and west and the more built-up Hudson River valley commercial areas. The Hudson River corridor channels airflows, while the Adirondack Park boundary nearby creates a distinct forested-urban pollen gradient throughout the season.

Does pollen in Glens Falls 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 Glens Falls 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 Glens Falls, 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.
