Local Environmental Conditions
Tree pollen in Headcorn comes mostly from oak and birch, with parks and mature gardens standing in contrast to the more built-up centre. The nearby local common land adds further grass and tree pollen exposure, particularly under inland breezes from the surrounding countryside. This mix of urban and rural influence gives Headcorn a fairly typical pollen pattern for the wider region.
Ask anyone with allergies in Headcorn and they'll tell you it's oak and birch that cause the trouble. Grass then takes over from May right through September, peaking around June and July for most people. Oak gets going around April and tapers off by May, before birch takes over, usually March to May. Good to know if you're planning anything outdoors that time of year.

Does pollen in Headcorn 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 Headcorn 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 Headcorn, 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. |
