Local Environmental Conditions
Downtown Alice, the city's small downtown in South Texas brush country, shares its vegetation profile with the broader Alice area, so pollen exposure here tracks the same regional sources found across the city. Exposure here depends mainly on how much tree and lawn cover surrounds the immediate site.
Downtown Alice tracks Alice's broader pollen pattern, with mountain cedar appearing from December before oak and elm peaks during March. Grass pollen then peaks through April and May, and ragweed extends the season into October. Mountain cedar's December-through-February peak is one of the most intense tree pollen events in the US, consistent with the wider Alice area.

How often is the Alice pollen forecast updated?

Does pollen in Alice 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 Alice 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 Alice, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
