Baytown's parks and the San Jacinto River corridor feature oak, pine, and introduced palm as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Houston metropolitan woodland and coastal prairie contribute substantial tree and grass pollen, while the Galveston Bay position means onshore Gulf breezes can periodically disperse urban pollen.

The Galveston Bay position means onshore Gulf breezes can periodically disperse pollen, while surrounding Houston metropolitan woodland and coastal prairie contribute substantial tree and grass pollen under prevailing southerly winds throughout the extended season.
How often is the Baytown pollen forecast updated?

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

Does pollen in Baytown 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 Baytown 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 Baytown, 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.
