Local Environmental Conditions
Beaumont's San Gorgonio Pass setting at the junction of the Inland Empire and Coachella Valley features California live oak, chaparral scrub, and introduced ornamental olive as the main pollen sources, with the pass's strong wind corridor shaping local dispersal. Mild, dry conditions allow an extended pollen season, while desert-adjacent grasses contribute through summer.
Beaumont's East Texas Gulf Coast setting produces a season opening in late January with pine and oak before grass from surrounding Gulf Coast farmland peaks through April and May. Mugwort and nettle extend exposure into September, while the flat, humid Gulf Coast setting allows pollen to disperse widely and the warm, wet climate advances the season compared to more northern Texas cities throughout.

How often is the Beaumont pollen forecast updated?

Does pollen in Beaumont 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 Beaumont 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 Beaumont, 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. |
