Local Environmental Conditions
The center of Bangor is surrounded mainly by built-up land, which covers around 50% of the nearby area, with a good deal of woodland. So much tree cover makes trees an important source of pollen locally. Grasses and weeds such as plantain and pigweed round out the local mix. Locally, street trees, parks and lawns are the main sources in the built-up parts.
Tree pollen comes first, peaking in mid-spring. Grasses take over in midsummer and keep pollen in the air into early fall. Later, plantain and pigweed keep weed pollen in the air from late spring into early fall. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

Does pollen in Bangor 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 Bangor 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 Bangor, 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. |
