Local Environmental Conditions
Aylsham's parks and green spaces feature oak and beech as the main tree pollen sources, with exposure varying between these greener areas and the more built-up town centre. Fields and hedgerows just outside town push grass pollen counts up noticeably once the dominant maritime airflow set in. Locals with allergies tend to plan around two peaks a year rather than one long stretch.
If you're wondering when hay fever kicks off in Aylsham, it's mostly down to oak and beech. Oak gets going around April and tapers off by May, with beech picking up between April and May. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Not a bad idea to stock up on antihistamines before it all kicks off.

Does pollen in Aylsham 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 Aylsham 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 Aylsham, 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. |
