Local Environmental Conditions
The center of Baytown sits among a blend of woodland and built-up land, plus some open grassland. With the Jacinto River nearby, riverside vegetation along its banks contributes to the local mix. Allergenic trees nearby include oak, juniper and elm. Grass pollen is plentiful, while ragweed leads among the weeds.
First to flower are juniper and elm, in midwinter. Oak follows in early spring, as temperatures climb to around 20°C, and tree pollen reaches its peak. Then come the grasses, strongest in mid-spring and fading by mid-fall. The season closes with ragweed from late summer into mid-fall. In warm, humid weather through spring, mold spores add to the mix, especially after rain.

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.

Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
