Local Environmental Conditions
U.S. Space & Rocket Center is a tennessee Valley city with oak-hickory forest on surrounding ridges. Tree pollen is significant from March through May. Valley topography concentrates pollen on calm mornings. Ragweed is a serious late-summer issue.
The pollen season at U.S. Space & Rocket Center mirrors Huntsville overall, starting with cedar and elm in February with oak following close behind through March and April. A grass pollen peak follows through April and May; ragweed extends the weed season into September. Mild winters across the Southeast push the pollen calendar earlier than in most of the country, a pattern felt across this part of Huntsville.

Does pollen in Huntsville 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 Huntsville 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 Huntsville, 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. |
