Residents in Bangor dealing with hay fever usually point to ash and alder as the culprits, particularly in spring near parks and gardens. Fields and hedgerows just outside town push grass pollen counts up noticeably once inland breezes from the surrounding countryside set in. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.

How often is the Bangor pollen forecast updated?

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.
