Local Environmental Conditions
In Annan, rowan and alder dominate the local tree pollen picture, with parks and tree-lined residential streets offering more exposure than the compact centre. The local common land nearby is a notable secondary source, feeding pollen into town whenever the wind shifts to the the coast. Hay fever sufferers here typically notice symptoms peaking in late spring, then again during the summer grass season.
Pollen season in Annan really gets going with rowan, followed not long after by alder. Rowan pollen typically runs from May to June, while alder follows on from January to April. On top of that, grass pollen runs May to September and tends to hit hardest in June and July. Useful to know if you tend to feel it every spring.

How often is the Annan pollen forecast updated?

Does pollen in Annan 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 Annan 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 Annan, 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. |
