Local Environmental Conditions
Surrounding Northamptonshire farmland contributes substantial grass and tree pollen, moving into town when winds blow from the west. On top of that, oak and beech are the two species driving most tree pollen in Woodford Halse, especially around parks and green corridors. It's a pattern shared by plenty of similarly sized towns nearby, shaped more by geography than anything unusual locally.
Want to know what triggers spring allergies in Woodford Halse? Start with oak, then beech. Expect oak pollen roughly from April to May, then beech carries on from April until May. Grass pollen then stretches from May into September, with the worst of it typically landing in June and July. Good to know if you're planning anything outdoors that time of year.

Does pollen in Woodford Halse 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 Woodford Halse 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 Woodford Halse, 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. |
