Local Environmental Conditions
The area around Chapel Hill is mostly open grassland, with a good deal of woodland. With a stream or river close by, riverside trees such as willow contribute to the local mix. Ash heads the list of allergenic trees nearby, ahead of olive and maple. Grasses and weeds such as plantain and pigweed round out the local mix.
Tree pollen peaks in early spring, when the weather warms to around 15°C and ash, olive and maple are in full flower. Grass pollen follows, peaking in late spring and easing off by early fall. Plantain and pigweed flower through much of the warmer half of the year. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Chapel Hill 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 Chapel Hill 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 Chapel Hill, 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. |
