Austin's pollen season opens with mountain cedar from December, one of the most intense early-season tree pollen events in the US. Oak follows through March and April, with grass peaking through May and June. Ragweed extends the season into October. The Texas Hill Country to the west is a major cedar source, while the flat to rolling landscape allows pollen to disperse widely across the city under prevailing southerly winds.

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 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.
