Georgetown's Texas Hill Country suburban setting features cedar, oak, and elm as the main tree pollen sources, with exposure varying considerably between the cedar-covered Hill Country terrain to the west and the more built-up commercial corridors along Williams Drive. The San Gabriel River corridor provides locally significant green space, while the transition between Hill Country cedar and Blackland Prairie oak creates distinct local pollen zones.

Does pollen in Georgetown 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 Georgetown 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 Georgetown, 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.
