Local Environmental Conditions
Built-up land and woodland share the area around the center of Hendersonville, plus some open grassland. The allergenic tree mix nearby includes oak and maple. Grasses are a major source, with ragweed adding to the weed pollen load. In the immediate area, planted trees and mown lawns are the main sources in the built-up parts.
Oak and maple lead the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in late spring and easing off by early fall. Ragweed brings a final peak from late summer into mid-fall. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

How often is the Hendersonville pollen forecast updated?

Does pollen in Hendersonville 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 Hendersonville 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 Hendersonville, 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. |
