Killeen's pollen season opens with cedar and elm from January, with mountain cedar producing intense early-season pollen through February. Oak follows through March and April, with grass peaking through May and June. Ragweed extends the season into October. The flat to gently rolling Central Texas landscape allows pollen from surrounding prairie and farmland to disperse widely across the city under prevailing southerly winds.

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

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 Killeen, 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.
