Austin's Hill Country fringe vegetation, anchored by Zilker Park and the Colorado River corridor, features oak, cedar, and pecan as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Texas Hill Country and prairie grasslands contribute substantial grass and tree pollen, while the flat to gently rolling landscape allows pollen to disperse readily under prevailing southerly winds.

How often is the Austin pollen forecast updated?

Does pollen in Austin 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 Austin 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 Austin, 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.
